Introduction
1 Introduction
1.1
Documentation content
This documentation describes how you can use intelligent Ethernet I/O modules, Ethernet and a
standard protocol such as TCP/IP to carry out even complex, “rapid” measuring tasks or signal
processing (such as determining average values) simply, reliably and cost-effectively via a PLC.
You can find detailed information about the respective MSX-Exxxx modules 1 in the ADDI-DATA
product catalog or in the relevant manuals.
Chapter 3.1 of this first part contains an overview of the compatible MSX-E modules.
1.2
Documentation structure
The documentation is divided into 3 parts:
Part 1: MSX-Exxxx and PLC: Principles
The first part of the documentation describes the principles of combining PLC and MSX-E modules.
Part 2: Connection to a PLC SIMATIC S7
Part 2 answers the following questions:
Which requirements are necessary to connect an MSX-E module to a PLC (hardware etc.)?
How are PLC and MSX-E modules parameterised?
Which settings generally have to be made and for what reason?
What do I have to be aware of when connecting one (or more) MSX-E modules to a PLC?
Part 3: Web interface description
The third part of the documentation explains in more detail the interface of the module website
(MSX-E3011 and MSX-E37xx) including the relevant settings.

The combination principle
2 The combination principle
2.1
More powerful PLC using intelligent Ethernet I/O modules
High flexibility and good value components have helped the PLC concept to reach its triumphant
success. Alongside control and regulation, PLCs are increasingly taking over other tasks such as alarms,
visualisation and data logging. Sensors and actuators ceased to be discrete some time ago, but can be
combined directly with the PLC at reduced wiring costs. Ethernet networks have proven themselves in
office IT for a long time now. The link between office IT and manufacturing IT meets the information,
monitoring and security requirements of modern management simultaneously.
Working in series makes programmable logic controllers slower than hardwired programmed logic
controllers. But demanding tasks such as the simultaneous reading of several channels or the
simultaneous acquisition of several signal types which originate from inductive/digital transducers,
shaft encoders or analog inputs are carried out using high- performance electronic measuring
equipment. Examples of this are an acquisition of several measurement values in a buffer in order to
make data available later or a very rapid acquisition and assessing of values independent of the PLC
cycle.

They can be cascaded and synchronised in the μs area.
¾ Simultaneous acquisition of different measurement values, e.g. inductive transducers and
position of the test item
Extended temperature range from -40 °C to +85 °C
Degree of protection IP 65: protection against jet water and dust

Parameterisation and monitoring via web server
¾ Measurement values directly on the screen of the technician's PC
¾ Saving of time, in particular when setting up measuring facilities, and flexibility
Easy connection to the PLC via TCP/IP
¾ Problem-free forwarding of measuring data to the IT level
¾ Remote maintenance with password protection and encryption
On-board RAM for data storage
Software updates can be easily installed at any time on the MSX-E modules.
Complex computing tasks (such as calculating several sensors in one result) can be realised as
required.
The MSX-E modules are available for different signal types:
• Digital I/O, 24 V
• Analog inputs, voltage or current, 16 bit
• Analog outputs, voltage or current, 16 bit
• Inductive transducers (HB, LVDT, Mahr-compatible)
• Incremental shaft encoders and transducers
• Sin/cos signals (1Vpp/11μApp) for shaft encoders or digital transducers
• Etc.
The mode of operation for all MSX-E modules is identical: Each module has a control side and a signal
side. The connection to the control side is the same for all modules.

2.4
Connection of an MSX-E module to a PLC
The MSX-E modules are connected to the PLC via Ethernet. Thus no special lines or communication
buses are needed. Additional modules can be added to the network very easily.
By means of an Ethernet controller, which can manage the TCP/IP protocol, the PLC is able to access the
additional modules. There are both hardware solutions (communication processor – CP) and software
solutions for this, whereas a hardware solution may be more suitable, depending on the application.
A separate hardware controller enables faster communication and reduces the load on the PLC CPU
less than software Ethernet management over the PLC CPU.
Fig. 2-2: MSX-E module: Connection to a PLC
2.5
The connection of an MSX-E module and a PLC
2.5.1 Data acquisition without programming (Autostart)
The actual measuring is parameterised and saved on the modules using the website. You can use the
Autostart function to load the measuring settings when the module is booted and to execute them
automatically. As such, no additional programming is required on the PLC.
Example:
16 analog inputs (8x +/-10 V, 8x +/-5 V), each with a speed of 25 kHz, should be acquired for a total of
0.5 seconds. The measuring should only be started once the test item is in the correct position, that is,
the PLC signals the start of the measuring to the MSX-E module using a digital 24 V output (hardware
trigger).
If the measuring has been previously parameterised and saved on the module, the module boots up
after it is powered on and waits for the hardware trigger.
If it identifies the hardware trigger, the measuring starts and the module acquires the measurement
values for 0.5 seconds. It subsequently waits for the next trigger.
www.addi-data.com
8
Via the receive function (FC6), the PLC can access the values and save these in a data block (DB)
(1 DWORD per channel). Afterwards they can be further processed as required. Due to their own
intelligence (ARM9), the modules can carry out calculations, e.g. of the minimum, maximum and
average values, independently.
Fig. 2-3: SPS: Retrieval of external measurement data
The configuration of the PLC and the MSX-E modules is described in detail in Part 2 of the
Instruction Manuals Ethernet I/O modules: Connection to a PLC SIMATIC S7.
2.5.2 Data acquisition with TCP/IP MODBUS
The acquisition of the measurement values can also be started using TCP/IP-MODBUS. Here, the
measuring or data acquisition is not parameterised on the modules and loaded when they are
powered up; instead, they are called to the PLC through MODBUS functions.
This operation is described in a separate documentation (“MODBUS Interface Description”).

Glossary
Ethernet
Ethernet is a system for connecting a number
of computer systems to form a local area
network, with protocols to control the passing
of information and to avoid simultaneous
transmission by two or more systems.
Trigger
A trigger is a pulse or signal for starting or
stopping a special task. Triggers are often used
for controlling data acquisition.
Counter
A counter is a circuit that counts pulses or
measures pulse duration.
IP address
This is a unique string of numbers separated by
full stops that identifies each computer
attached to the Internet. Usually it also has a
version containing words separated by full
stops.
LSB
= least significant bit
LSB is the lowest order bit in a digital quantity.
MSB
= most significant bit
MSB is the highest order bit in a digital
quantity.
PLC
= programmable logic controller
A PLC is a digital computer used for
automation of electromechanical processes,
such as control of machinery on factory
assembly lines. PLCs are used in many different
industries and machines such as packaging and
semiconductor machines. Unlike generalpurpose computers, the PLC is designed for
multiple inputs and output arrangements,
extended temperature ranges, immunity to
electrical noise, and resistance to vibration and
impact. A PLC is an example of a real-time
system.
Socket
A socket is a bidirectional software interface to
interprocess (IPC) or network communication.
Sockets are a standardised interface (API)
between the network protocol implementation
of the operating system and the actual
application software.

MSX-E module and PLC configuration
1 MSX-E module and PLC configuration
1.1
Prerequisite
The prerequisite for using MSX-E modules with a PLC is that the PLC must have an Ethernet interface
and can open an active TCP connection (TCP sockets).
1.2
Principle structure
Each MSX-E module has a data server that provides the acquired measurement values. The PLC can
access these measurement values using a TCP connection, thereby reading the data.
The acquisition itself can be started either by an external trigger (digital 24 V input) or automatically.

In the PLC, the data is read using the FC6 function (receive function) and then stored in a data block
(DB). From here, it can be further processed as required.

Program overview

OB1: This operation block calls up the receive function (FC6).
FC6: With this function, data is read from a TCP connection (socket) and subsequently saved in a data
block.
1.4
Data conversion
Note that the MSX-E modules send data in the Little Endian format (Intel format), whereas an S7 PLC
works with Big Endian coding (Motorola format).
As a result, the values of the MSX-E modules on the PLC have to be converted into the Big Endian
format (Motorola format). This data coding plays an important role as otherwise the measurement
results will be interpreted incorrectly.
ADDI-DATA provides you with a corresponding conversion function:

Introduction
ADDI-DATA provides a software packet that displays the connection between an MSX-E module and an
S7 PLC. The example is based on a SIMATIC S7 PLC from Siemens.
If you want to use an S7-compatible PLC from a different manufacturer (such as IBH-Softec, Vipa etc.),
then you have to use the relevant manufacturer’s original FCs. You may also have to adapt the data
blocks etc. (Siemens: 9 DWORD; Vipa: 36 bytes).
The example given for the S7 from Siemens is called BasicSample and was developed for the
S7-300’s Ethernet connection with CP343-1. It is used for reading values from the TCP connection
(TCP socket).
2.2
S7 Ethernet configuration
The following configuration is based on an S7-300 with CP343-1. Your PLC may display other menus,
although the settings are the same nevertheless.
Fig. 2-1: SIMATIC Manager: S7 Ethernet configuration
Open the SIMATIC Manager and then the BasicSample project.
To configure the TCP connection, double-click on the “Ethernet” object name.

11
Fig. 2-3: TCP connection properties: General information
So that the S7 can create the connection to the MSX-E module, Aktiver Verbindungsaufbau
[Active Connection Setup] must be selected.
On the right-hand side of the figure above, you see the Bausteinparameter [Block Parameters] that
have to be used together with the FC6 (AG_RECV) function. The connection ID (socket ID) and the
address are specified.
Click on the Adressen [Addresses] tab.
www.addi-data.com
12
Fig. 2-4: TCP connection properties: Addresses
In Lokal PORT [Local PORT] enter the port number of the S7. This must correspond to the
MSX-E module’s port number.
In Partner enter the MSX-E module’s IP address and its port number. The port number must
agree with the one that was defined on the module’s web interface.
To check this, open a web browser (such as Firefox or Internet Explorer) and enter the following
address: http://IP address of the module.

Reading the measurement data
3 Reading the measurement data
3.1
Introduction
As already mentioned in chapter 2, ADDI-DATA provides you with an example of an S7 PLC from
Siemens. The aim of this is example is to demonstrate how the PLC reads the measurement data of an
MSX-E module from a TCP connection.
3.2
Prerequisites
Ensure that the following prerequisites are fulfilled:
•
•
•
•
3.3
Siemens CPU313C-2DP (PLC)
Siemens CP343-1 Lean (Ethernet module for the PLC)
FC6 (AG_RECV) for S7-300 (function for asynchronous communication)
S7 example for STEP7.

3.3.1 FC1: Converting data to the Motorola format
Description:
With the MSX-E modules, the data is displayed in the Intel format, whereas the S7 PLC displays it in the
Motorola format.
If your PLC already uses the Intel format, you do not need this function block. However, if your PLC
works in the Motorola format, you can use this block to convert the values.
Input parameters:
INTEL: Raw value in the Intel format as a DWORD data type that is read from the MSX-E module
Output parameters:
MOTOROLA: Value in the Motorola format as a DWORD data type
Example of the sequence of function calls:

17
3.3.2 FC3: Converting a DWORD data type to a REAL data type
Description:
On the MSX-E modules the measurement values are coded to 4 bytes and sent via the TCP connection
as byte packets. By default the measurement values are sent as raw values.
Example: Module MSX-E3011 with Gain 1 Unipolar
If 10 volts are measured, the module does not send the value 10, but 65535. This value is designated as
a raw value.
65535 is a raw value that is converted to the suitable unit:
((Voltage range/resolution) x raw value) + minimum voltage
((20 / 65535) x 65535) + (-10) = 10 volts
If the modules convert the raw values to the appropriate unit immediately and send them, no
additional conversion is required on the PLC. The values that are read from the TCP connection should
first be displayed correctly and then converted with a type cast to the REAL data type. The type cast is
required, because the values that are received cannot be directly sent and received as a REAL type.
Input parameters:
RAW: Raw value that was converted by the module to the appropriate unit, as a DWORD data type
in the Motorola format
Output parameters:

3.3.4 FC7: Converting to volts or mA
Description:
This function can be used with the MSX-E3011 module to convert raw values into volts.
Input parameters:
RAW: Value as a REAL data type that is already displayed in the Motorola format
(see Functional call sequence)
MIN: Value as a REAL data type that defines the minimum voltage value of the voltage range.
Example: Module MSX-E3011
With Gain 1 Bipolar, this value is equal to -10 volts. With Gain 2 Bipolar, this value is -5 volts.
MAX: Value as a REAL data type that defines the maximum voltage value of the voltage range.
Example: Module MSX-E3011
With Gain 1 Bipolar, this value is equal to +10 volts. With Gain 2 Bipolar, this value is +5 volts.
RESOLUTION: Value as a REAL data type that defines the resolution of the measurement range.
Example: An MSX-E3011 module has a resolution of 16 bit (= 65535 steps).

3.3.5 FC20: Dynamic Reading of a DWORD Value from a Table
Description:
This function block is not absolutely necessary. It enables a DWORD value to be read from a DWORD
table (which is located in a data block). Instead of a fixed definition of the table index, the latter can
be dynamically managed using this block. However, FC20 does not involve any error management
(such as error = index > table width).
Input parameters:
INDEX: Index as an INT data type to be read from the table cell
PDB: Data block in which the table is located as a DWORD data type
Output parameters:
DATA: The value that is read as a DWORD data type

3.3.6 FC21: Dynamic writing of a REAL value to a table
Description:
This function block is not absolutely necessary. It enables a REAL value to be written from a REAL table
(which is located in a data block). Instead of a fixed definition of the table index, the latter can be
dynamically managed using this block. However, FC21 does not involve any error management (such as
error = index > table width).
Input parameters:
INDEX: Index as an INT data type to be written to the table cell
PDB: Data block in which the table is located as a REAL data type
DATA: Value to be written as a REAL data type
www.addi-data.com
22
3.3.7 FC6: Reading data from a network connection
Description:
This function block was created by Siemens and enables data to be read from a network connection.
Input parameters:
ID: 1 is the number of the communication identifier.
LADDR: The value W#16#0100 is the address of the function block.
Fig. 3-2: TCP connection properties
www.addi-data.com
23
RECV: This is the indicator in which the data has to be saved; in this case, in DB101.
P#DB101.DBX0.0 BYTE 36 means that an indicator to the offset 0 is passed to the DB101 data
block (RAW_DATABLOCK) and 36 bytes (9 DWORD) are expected. The number of bytes expected
may change as required. Ensure that the table in which the values are saved is sufficiently wide.
The number of bytes always corresponds to a data packet.
The size of a data packet is specified in the module’s web interface.
On the web interface, click on the Acquisition/Autostart menu option.
Select the Auto-Refresh or Sequence mode.
In the Binary data packet structure or Binary data frame packet structure section, size of a
packet in bytes displays the size of the data packet.
Fig. 3-3: Acquisition/Autostart: Binary data packet structure
www.addi-data.com
24
If the function block received the values from the MSX-E module, you will see the values in the
following sequence in the table for the target data block:
RAW[0]: contains the value “counter”
RAW[1]: contains the value “channel 1”
…
The following example is based on an S7 screenshot (Binary data packet structure) and a data block
containing the RAW table as a DWORD data type with a width of 36 bytes.
Fig. 3-4: Data block with the RAW table
Fig. 3-5: RAW table in the data block
Output parameters
NDR: If the number of bytes are read and NDR equals 1, then no error occurred. If NDR equals 0,
then check ERROR and STATUS to find the errors that are displayed.
LEN: This is the number of read bytes. The number must be 36 (= 9 x 4 bytes).

Please configure networks 1-3 according to the description in the following chapters.
4.1
Configuring the module using the web interface
This chapter lists only those steps that are necessary to apply the programming example BasicSample
to a module.
For a detailed description of the web interface, see Part 3 of the Instruction Manuals Ethernet I/O
Modules: Web interface description.
You can use the default settings of the BasicSample to configure an acquisition in auto-refresh or
sequence mode.
You must ensure that, in the sequence mode, the value of the sequence counter is not transmitted by
default, whereas in auto-refresh mode this value is always available. For this reason, you have to select
the relevant setting on the web interface (see chapter 4.1.2).
4.1.1 Auto-refresh mode
On the web interface, from the left-hand side menu, select the Acquisition/Autostart option.
In the Type of acquisition section, click on the Auto refresh acquisition mode.
From the list below, select the transducer type that is used. It is the same for all channels.

Define the division factor.
In the Channels to acquire area, select the channels you want to acquire.
Optional:
The module can calculate an average value. You can select the calculation type in the Average mode
list. This calculation can be carried out per sequence or per channel.
With the per sequence calculation, all selected channels are acquired at once for each sequence.
Average value is the value that is used to calculate the average values.

S7: Example description
4.2.1 OB1: Main block
Description:
OB1 (organisation block 1) is executed periodically. As soon as it ends, it starts again. To obtain a
simple overview of the entire source code, all function blocks are called from OB1 in BasicSample.
4.2.2 Network 1: Definition of the number of values to read
Description:
Enter the number of values to read.
In this example, 9 values are read. The first value can be a value of the sequence counter, or a value of
the 8 channels. If a sequence counter value is expected, set the COUNTER_AVAILABLE variable. If not,
this variable should be reset.
www.addi-data.com
34
Simple S7 example
4.2.3 Network 2: Selecting the appropriate conversion unit
Description:
Before the BasicSample is transmitted to the S7, you need to define in network 2 the conversion unit
using the CONVERT_IN variable.
CONVERT_IN = 0: The module does not return any raw values, only the converted values (type cast is
executed).
CONVERT_IN = 1: The module returns raw values. With the MSX-E37xx module, these are converted
by the PLC into the unit millimetres.
CONVERT_IN = 2: The module returns raw values. With the MSX-E3011 module, these are converted
by the PLC into the unit volts.
As already mentioned, you can determine on the module’s web interface that the measurement values
are converted into the appropriate unit (see chapter 4.1.2: Other information in data packet
section).
4.2.4 Network 3: Reading the measurement values from the TCP connection
Description:
FC6 attempts to read 36 bytes from the MSX-E module from the TCP connection ID 1 and ADDR
W#16#100. If no connection errors occurred and the 36 bytes are available, the RCV_NDR variable is set
to “true”.
The RECV (P#DB101.DBX0.0) input parameter is a pointer to the data.
DB101 is a data block to which the 36 bytes are copied (36 bytes = 9 x DWORD). RECV can be adapted
as required. If the number of bytes to read was changed, you should also check whether the number of
elements in the DB101 and DB102 data blocks is sufficient.
For more information, see chapter 3.3.7.
www.addi-data.com
35
Simple S7 example
4.2.5 Network 4: Initialising the index
Description:
The program uses two data structures.
The RAW_DATABLOCK (DB101) structure contains a DWORD table in which the raw values that were
read are available.
The data structure REAL_DATABLOCK (DB102) contains a REAL table in which the converted raw values
are saved as a REAL data type. The INDEX variable is set to 0. INDEX is used to manage the table index
dynamically.
www.addi-data.com
36
Simple S7 example
4.2.6 Network 5: Display in Motorola format
Description:
From the RAW_DATABLOCK table, a raw value is read from the relevant cell in the INDEX. This value is
converted from the Intel format (MSX-E module) into the Motorola format (PLC).
4.2.7 Network 6: Managing the sequence counter value
Description:
If the sequence counter value is expected and the INDEX is 0, then the value is a sequence counter
value. The program then jumps into the network that contains the CPT marking. The sequence counter
value is always the first value in the table.
www.addi-data.com
37
Simple S7 example
4.2.8 Network 7: Type cast instead of conversion
Description:
As the module already returns converted values, no additional conversion is required.
MOVE copies the DWORD raw values into a variable of the data type REAL (type cast). Afterwards, the
program jumps into the network with the marking SAVE.
4.2.9 Network 8: Converting to millimetres
Description:
The module returns raw values. With FC3, the DWORD raw values are converted to the REAL data type,
and with FC4 they are converted into the unit millimetres. Subsequently, the program jumps into the
network with the marking SAVE.
www.addi-data.com
38
Simple S7 example
4.2.10 Network 9: Converting to volts
Description:
The module returns raw values. With FC3, the DWORD raw values are converted to the REAL data type,
and with FC7 they are converted into the unit volts. The program then jumps into the network that
contains the SAVE marking.
4.2.11 Network 10: Processing the sequence counter value
Description:
The sequence counter value is converted as a DWORD data type into REAL. Afterwards, the program
jumps into the network with the marking SAVE.
www.addi-data.com
39
Simple S7 example
4.2.12 Network 11: Save and check
Description:
FC21 saves the value in the REAL table. ADD_I increases the INDEX variable so that the next raw value
can be read. CMP < I checks whether all raw values were read. If not, then the program jumps into the
network with the marking LOOP.

Auto-refresh and sequence mode
i
IMPORTANT!
The PLC requires a certain time to read the values from the TCP
connection (PLC cycle > acquisition cycle) if you do not configure
an average value calculation in the auto-refresh mode, or a delay
in the sequence mode. This is also the case if a small “division
factor” is configured in both modes.
This can result in a delay between the actual status of the channels
and the measurement values that are read.
If the packets from the TCP connection are not read quickly
enough, there may be a FIFO overrun which causes the module to
terminate the connection to the PLC.

Trigger
5.2.1 Introduction
With the MSX-E modules, the measurement can be started by a trigger.
For more information, see Part 3 of the Instruction Manuals Ethernet I/O Modules: Web interface
description.
The following information describes how the acquisition start can be controlled using a hardware
trigger. Each time that a rising edge is identified at the MSX-E module’s trigger input, the module
sends a packet with a sequence counter value and 8 measurement values.
www.addi-data.com
43
Recommendations
5.2.2 Module configuration
The configuration described in chapter 4.1.1 (auto-refresh mode) or chapter 4.1.2 (sequence mode) can
be used as a basis for defining the following trigger configuration:
5.2.3 BasicSample: Example of trigger enhancement
To start the acquisition, you can set a digital output (A124.0) for the module in network 2. This has to
be connected with the module’s digital trigger input (Trig/Sync In).

5.3
Querying the current measurement values in auto-refresh mode
5.3.1 Introduction
The PLC has the option of querying one or more current measurement values asynchronously (without
a hardware trigger). This method can be used if only one or several current measurement values of the
module are required at a certain time.
The following chapter describes how a current packet containing a sequence counter value and eight
measurement values is read. The BasicSample is adapted accordingly for this purpose
(see chapter 5.3.3).
Note that the transmission time is extended if several PLCs access an MSX-E module simultaneously.
5.3.2 Module configuration
The configuration described in chapter 4.1.1 (auto-refresh mode) or chapter 4.1.2 (sequence mode) can
be used as a basis.
On the web interface under Dataserver, in the Blocking TCP/IP transfer section, for activate
blocking TCP/IP transfer? select the option yes.
For TCP/IP transfer timeout? you can set a timeout of 2 seconds so that the data server does not
permanently block the data.

In the Action section, click on Save and then on Restart.
Fig. 5-3: Web interface: TCP port number
5.3.3 BasicSample: Adjustment example for querying the measurement values
So that you can read the current values, two data packets have to be acquired. Only the second packet
is taken into account, as the first packet contains previous measurement values.
The BasicSample is adjusted as follows:
In network 3, copy function block FC6 and insert it to the right of the original block.

Connecting several modules to a PLC
You can connect several MSX-E modules to a PLC. In this case, for each module you have to create a
new TCP connection (socket).
To do this, follow the instructions in chapter 2.2 and enter a different port number in the field
Eigenschaften – TCP-Verbindung for each module.

2.2.3
Average setup (Calculation of the Average Value)
The module can calculate an average value. You can select the calculation type in the Average mode
list (see Fig. 2-3). This calculation can be carried out per sequence or per channel.
With the per sequence calculation, all selected channels are acquired in one go for each sequence.
Average value (see Fig. 2-3) is the value that is used to calculate the average values.
Fig. 2-3: Auto-Refresh Mode: Average setup
Example
The module is parameterised with the average mode per sequence and acquires channels 1 to 8.
Average value contains the value 10. This means that a sequence consists of eight channels and it is
acquired ten times. (As such, each channel is also acquired ten times.)
Fig. 2-4: Average mode: Acquisition per sequence
A sequence consists of one or more channels, but for
each acquisition it consists of the same number of
channels. Here, for example, it consists of eight
channels.

value channel 1) / 10
Average value of channel 2 = (sequence 1, value channel 2 + sequence 2, value channel 2 + … + sequence 10,
…
Average value of channel 8 = (sequence 1, value channel 8 + sequence 2, value channel 8 + … + sequence10,
www.addi-data.com

Acquisition modes
The network client will not receive ten sequences, but only one data packet with the average values
from channels 1 to 8.
With the per channel calculation, each selected channel is acquired as often as corresponds to the
value of the Average value.
Fig. 2-5: Average mode per channel
Example
The module is parameterised with per channel and acquires channels 1 to 8. Average value contains
the value 10. This means that each channel is acquired ten times.

Channels to acquire (Channel Selection)
In the Channels area, select the channels you want to acquire.
You can define the sequence of the channels. A channel can be acquired several times per sequence.
2.4
Delay (Wait Time)
In the Delay section you can define the wait time between the individual sequences. There are two
modes, which are explained below.
Fig. 2-7: Sequence Mode: Delay
With time unit you can define the unit of the delay in milliseconds (ms) or seconds (second). Enter
the value of the delay in the Delay value. The minimal delay value displays the minimal value of
the delay.
For mode, if you select option none, no delay is used.

Acquisition modes
Mode 1
The time between the start of two subsequent sequences is defined as the delay.
Example
After the start of the acquisition (see the “Start” button in the Start/stop acquisition section), the

Number of sequences to acquire (Number of Sequences)
Fig. 2-8: Sequence Mode: Number of sequences to acquire
You enter the number of sequences to acquire in the sequences to acquire field.
If this value is 0, the acquisition is continuous. If it is a value between 1 and 4294967295, the number of
sequences is predefined.
Example
To acquire four sequences, the sequences to acquire field must contain the value 4. As a result, when
you start (see the “Start” button in the Start/stop acquisition section), four sequences are acquired.

www.addi-data.com
17
Acquisition modes
In the sequences before sending field, you define the maximum number of sequences that have to
be acquired before the measurement values are sent to the target system. If the module does not have
sufficient memory to store the required number of sequences, the measurement values are sent earlier,
that is, before the maximum number of sequences to be acquired is reached.
sequences before sending is used to reduce the network traffic load and the CPU resources of the
MSX-E modules.
Example
When you start (see the “Start” button in the Start/stop acquisition section), the acquisition begins.
If two sequences are acquired, the measurement values are sent to the client.

Acquisition Mode of Common Parameters
3 Acquisition Mode of Common Parameters
3.1
Trigger configuration
The acquisition can be started by an external signal. This can be a digital input signal or a
synchronisation signal.
For Trigger source, if the option disabled is selected, the trigger is not used.
For Trigger source, if the option hardware is selected, the hardware trigger takes place using the
module’s trigger input. The hardware trigger enables the start of the acquisition to be controlled with
a digital signal (24 volt).
The digital output of a PLC can start one or more acquisitions on the module. The hardware trigger
input can also be used to synchronise the MSX-E module with another module.
The hardware trigger signal can be passed from one module to another.
www.addi-data.com
19
With Trigger mode, if the one-shot trigger mode is selected, only one acquisition starts.
With Trigger mode, if the option sequence (= multi-shot) is selected, a defined number of
acquisitions starts.
Hardware trigger count defines the number of edges after which an acquisition is started.
In the sequence trigger mode, Number of sequence(s) per trigger defines the number of
sequences that are acquired after a trigger.
The Hardware trigger active edge field defines the type of edge with which the module identifies a
trigger.
Examples of edges
Rising: Rising edge

Examples of hardware triggers with one-shot
1) To start the one-shot acquisition after three rising edges, you can use the following
parameters:
After the start (see the Start button in the Start/stop acquisition section), the module waits for
three rising hardware edges. Once the three edges have been identified, the acquisition starts.
Start enable
Acquisition
2) With Hardware trigger active edge, rising is selected again, and the value 1 is entered for
Hardware trigger count.
The trigger starts only one acquisition, which begins with the first hardware edge after you start (see
the Start button in the Start/stop acquisition section).

3) With Hardware trigger active edge, both is selected, and the value 3 is entered for Hardware
trigger count.
After you start (see the Start button in the Start/stop acquisition section), the module waits for
three rising and falling hardware edges. Once the three edges have been identified, the acquisition
starts.
Start enable
Acquisition
4) With Hardware trigger active edge, both is selected again, and the value 1 is entered for
Hardware trigger count.
If several edges occur after you start (see the Start button in the Start/stop acquisition section), the
acquisition is started (triggered) with the first edge. The subsequent edges are ignored.
Start enable
Acquisition

Examples of hardware triggers with sequence
1) To start each acquisition after one rising edge, you can use the following parameters:
Start enable
Acquisition
2) For Hardware trigger active edge, both is selected and Hardware trigger count contains the
value 3.
After you start (see the Start button in the Start/stop acquisition section), the acquisition is started
after three rising and falling edges. At the end of this sequence, the next sequence is started after
three rising and falling edges, and so on.

Synchro trigger
In contrast to a hardware trigger, a synchro trigger is created from a different MSX-E module. As a
result, several MSX-E modules can be acquired in parallel. You can select one-shot and sequence
trigger modes, just like with the hardware trigger.
3.2
Digital trigger input filter (Digital Filter)
To suppress interference from external trigger signals, you can use a digital filter which is configured
via software. You can define filter times of 250 ns to 16.38 ms. If the filter is activated, each positive or
negative impulse that is less than the defined filter time is suppressed. Value 1 corresponds to a filter
time of 250 ns.
no deactivates the filter; it is activated with yes.
Example 1
Filter value contains the value 65535.
The calculation is as follows: 65535 x 250 ns = 16.38 ms.
This time corresponds to a frequency of approximately 30.5 Hz. If the trigger signal is faster than 30.5
Hz, it is suppressed.
Example 2
The acquisition should be triggered after a rising edge.

15ms
The trigger signal always lasts longer than 10 ms. However, as it is not clean and bounces, this creates
short spikes of ~4 ms. So that these bouncing signals are no longer identified as triggers, a filter of 10
ms is configured.
3.3
Trigger signal duration > 10 ms:
Trigger identified as a trigger
Trigger signal duration < 10 ms:
Trigger is ignored
Autostart (Automatic Acquisition Start)
As soon as the MSX-E modules are switched on, they can load a predefined configuration and execute
it. In other words, the acquisition is started automatically when the module is powered up.
You can also use the current configuration as the autostart configuration.
www.addi-data.com
26
3.4
Action on current configuration (Save the Configuration)
The Check button tests the current configuration. If a configuration parameter is not correct, an error
message is displayed.
Save saves the current configuration on the module.
Reload saved loads the saved configuration.
The Display running configuration button restores the module’s current configuration on the
website.
f
i
IMPORTANT!
The configuration determined on the web interface is saved locally, that
is, only on the module itself.
However, it is possible to read the configuration from the module using
a computer using the direct access sample
MSX-E Common\ Direct Access Samples\Visual C++ 6.0\AutoConfig
and to save it to a file on the computer or a different storage medium.
The externally saved configuration can also be loaded back onto the
module using the same sample.
www.addi-data.com
27
3.5
Other information in data packet / Data frame (Additional Data)
By default, only the acquisition values are sent to the client. However, if you activate the following
options, it can also receive additional information.
In sequence mode, the sequence counter counts the number of sequences that were already acquired.
If Send sequence counter is activated, the sequence counter’s value is sent in addition to the data.
Send time stamp with data: A time stamp is sent that contains the date of the acquisition.
Convert data in… or Data in analogue format: With this option, the module can convert the raw
values immediately to the correct unit. The unit depends on the module type. For a MSX-E37xx
module, the unit is millimetre (mm); for a MSX-E3011 module volts or amps. As the conversion affects
the MSX-E CPU to a certain extent, this can result in slower send speed times.
Invert value inverts the value signs, for example -5 is sent instead of 5.
www.addi-data.com
28
3.6
Binary data packet structure / Binary data frame packet structure
(Packet Format)
The module sends the data over the network to one or more clients. So that the client can interpret
the values correctly, the values are formatted. This format is defined as Binary data packet structure
or Binary data frame packet structure (the name depends on the module type). All measurement
values and the additional data such as the time stamp form a group of values that are called a packet.
The packet size is displayed in size of a packet in bytes.
i
IMPORTANT!
The module sends the packets in the Intel format (Little Endian).
Example
A packet consists of a counter value and eight measurement values. The module always sends one or
more of these packets. The data client should be programmed in such a way that it can receive a
packet and interpret it correctly.

MSX-E370x: Specific Information
4 MSX-E370x: Specific Information
The following information can be found under the Acquisition/Autostart menu option.
4.1
Transducer type (Transducer Selection)
From the list below, select the transducer type that is used. This is the same for all channels.
4.2
Division Factor (Switching Time)
The division factor specifies the number of periods that are required by the A/D converter to switch
from one channel to another, that is, to switch from the voltage level of the first channel to the
voltage level of the second channel.
The duration of a period is calculated from the transducer’s scanning frequency. The higher the
division factor, the more precise the result, although this slows down the measurement.

MSX-E3011: Specific Information
5 MSX-E3011: Specific Information
The following information can be found under the Acquisition/Autostart menu option.
5.1
Conversion time
Conversion time determines the switching time that is required from one to the other channel.
The unit of this conversion time can be defined as microseconds, milliseconds or seconds.
The range in which the conversion time can lie is based on the unit that is selected:
Microseconds: 10 to 65535
Milliseconds: 1 to 65535
Seconds: 1 to 65535
If only one channel is selected, this parameter is insignificant.
www.addi-data.com
32
5.2
Configure polarity (Polarity Selection)
For each channel that is selected, you can define the polarity. Unipolar and Bipolar are available
options.
With Unipolar, the module measures only the values in the positive range from 0 volts or amps.
With Bipolar, the values in the negative range are also measured.
The size of each relevant measurement area depends on the selected gain (see the following
chapter 5.3).
In the figure above, channels 11 to 16 are missing.
5.3
Configure gain (Gain Selection)
The Gain enables the measurement to be adapted to the input voltage range or the input current
range to achieve greater precision. Two gain types are available.
The size of each measurement area depends on the gain and the polarity:
Gain 1 Unipolar: 0 to +10 volts or 0 to 20 mA
Gain 1 Bipolar:
www.addi-data.com
-10 to +10 volts or -20 mA to +20 mA
Gain 2 Unipolar: 0 to +5 volts
or 0 to 20 mA
Gain 2 Bipolar:
or -20 mA to +20 mA
-5 to +5 volts
33
Example
Gain 1 in Unipolar 16 Bit:
(10 / 65535) = 1 Bit (corresponds to approx. 0.0001525 V)
Gain 2 in Unipolar 16 Bit:
(5 / 65535) = 1 Bit (corresponds to approx. 0.00007695 V)
i
IMPORTANT!
We recommend using gain 2 for current measurements.

Network (Network Parameters)
Weboberflächen-Beschreibung
6 Network (Network Parameters)
Using this menu option on the web interface, you can change your module’s network configuration.
6.1
Network configuration
In the Network address of the module field, enter an IP address in the form 127.0.0.1 and click
on Save. The new value is used when the module is restarted.
In the Network hostname field you can enter up to 64 characters. This change takes immediate
effect when you click on Save.
6.2
Syslog (Network Logging)
The module can send logging information to a system in the network by using the syslog protocol.
In the Syslog Target field, enter the IP address of the system that receives the information and
click on Save. If the Syslog Target field remains empty, this function is deactivated.
The Syslog Port field contains the port number (UDP) that should be used. This is between
1 und 65535. 514 is defined as the default value.
The new configuration takes effect when the module is restarted.
www.addi-data.com
35
Data server
7 Data server
The data server is the network service that delivers the acquired data to clients via TCP/IP or UDP
sockets.
7.1
Network protocol
The data server supports both TCP/IP and UDP/IP protocols.
TCP/IP mode
This mode is based on the client/server programming model. Clients have to be first connected to the
server and read data on the socket. This protocol guarantees the packet delivery; otherwise the
connection will fail.
In the TCP port number field, enter the port number that is used to create the connection with the
module. The default port number is 8989.
i
IMPORTANT!
A maximum of five clients can be connected to the server
simultaneously. This applies to all MSX-E modules from firmware
revision 3230.
UDP/IP mode
The UDP/IP mode is based on the programming model of separated data streams.
The data server sends data packets to the defined network client(s). The client has to open a socket
and read data. The delivery of data packets is not guaranteed, since the data server cannot check
whether the delivery was successful. You have to specify UDP/IP clients precisely to the data server in
the UDP/IP network targets field.
In the UDP/IP network targets, enter a character string of the IP address and port number, separated
by a blank space, as shown below: IP1:PORT1 IP2:PORT2 ... IPn:PORTn.
Example: 192.168.99.2:8080 192.168.99.3:8888
www.addi-data.com
36
Data server
7.2
Blocking TCP/IP transfer
In this mode you can define a TCP/IP timeout in the form s.μs.
With the value “1.0", the timeout is 1 second, that is, the server waits one second for a read
confirmation from the data client. At the same time, it blocks the reading of the acquired data. If it
does not receive the client’s confirmation after a second, the connection to this client is broken. If it
does, then the data server continues with calling up the acquired data.
With the value “0.0”, the server would permanently block the data as it would wait constantly for a
read confirmation from the data client.
If the option yes is selected for activate blocking TCP/IP transfer, although the data server’s
throughput rate is reduced, this is an advantage if the connection with the client is unexpectedly
blocked.
If for activate blocking TCP/IP transfer the option no is selected, the actual TCP/IP timeout
corresponds to the protocol’s permitted minimum. In this mode, network problems are easier to
identify than with the yes mode; moreover, the server’s throughput rate is higher.
www.addi-data.com
37
Data server
7.3
Data caching )
i
IMPORTANT!
You can only use the cache in TCP mode.
By default, the values that are acquired by the MSX-E module are lost unless at least one client is
connected that reads them.
The data server can cache the data so that no data is lost. If a client is connected, it first receives the
cached data and only then does it receive the newly acquired data.
Data caching mode
The data server can work in either Volatile mode or in Persistent mode.
Volatile: In this mode, the data is cached in the RAM buffer. However, this data is lost when the
module is switched off. A high throughput rate is reached in Volatile mode.
Persistent: The data is cached internally in a file. If the module is restarted, the previously acquired
data is still available.
i
IMPORTANT!
The storage method means that you achieve a lower throughput rate
with the Persistent mode than with the Volatile mode.
Read mode
The data server can delete or keep data if a client is connected.
Delete mode: The cache is not used in this mode. Newly acquired data is not cached, but sent via
TCP/IP directly to the connected clients
Keep mode: Data is systematically cached in the cache without being deleted there.
www.addi-data.com
38
Data server
Write mode
The data server can work in Simple mode or in Circular mode. These modes define the procedures
in the event of a cache overrun.
Simple mode: Newly acquired values are ignored if the cache is full.
Circular mode (ring buffer): If the cache is full, the oldest values are overwritten by the newest
ones. If a client is connected, it receives the older values first. This mode is recommended if you use a
time stamp.
Example with a ring buffer containing a maximum of 7 values:
1) Data 0 is the oldest
measurement value and Data
6 the newest. The ring buffer
is full.
If a client is connected,
then the data is sent from
Data 0. The next value

Data server
Cache size in bytes
An additional parameter is the cache size. This is the number of bytes that the cache can handle. The
maximum value depends on the number that is available to the storage medium. To avoid the risk of
the system crashing, the server allocates at most 80% of available resources, that is, 20% of the
memory remains free.
Note that in persistent mode, 16 bytes are used for saving metadata. To maintain the actual memory
size for data, this has to be deducted from the cache memory size.
7.4
Action (Save and Restart)
If you click on Save, the module saves your new configuration. This is reused each time the system
starts.
The Reload button reloads the website with the saved configuration. Any changes that were not
saved will be lost.
Click on Restart to restart the data server.
If you click on Restart & reset, the data server is restarted. If the data server was configured in
Persistent mode, the content of the cache file is deleted.
i
IMPORTANT!
If you have changed the configuration, you first have to save it by clicking on
Save and then click on Restart & delete to restart the data server and to empty
the cache.
