Hints on operation
1 Hints on operation
Multi-temperature controller version KS800-RS is provided with a serial, bussable RS485 interface which
can be used for transmission of process, parameter and configuration data. Connection is via (a) 9-pole
sub-D socket(s)(connector(s)). The serial communication interface permits connections to supervisory PLCs,
visualization tools, etc.
An RS485/422 hardware interface is realized. The protocol available on this hardware is:
w
the PCI protocol, which is based on an ISO 1745 frame,
Communication is according to the master/slave principle. KS800 is always slave. The software of the serial
interface is implemented as standard in the firmware.
Another standard interface is the PC interface. This interface is used for connecting an engineering tool,
which runs on an external PC.
1.1 Connecting the interface
Version KS800-RS offers an RS485 or RS422 interface. ‘RS422’ as available in this product means an
RS485 4-wire interface. A driver for reception and a driver for sending are available.

If an RGND connection is required with an RS485 adjustment, a 100 Ohm resistor must be mounted across
terminal 5 (RGND) and terminal 5 of the interface converter by the user.
The outputs are galvanically isolated.
The interface mode is half-duplex.
Installing appropriate cables must be done by the user, whereby the general cable specifications according to
EIA RS485 must be taken into account.

2 Interface protocol
2.1 Protocol layer 1
Bus connection is physical:
w
w
via the PC interface as a TTL signal (COM 1)
via an RS485/422 connection (COM 2) with version KS800-RS.
2.1.1 Data format
The following transmission format, fixed, must be used:
w 1 start bit,
w 7 bits ASCII value or 7 bits binary
w 1 parity bit (EVEN)
w 1 stop bit
LSB is transmitted first, MSB is parity bit.
2.1.2 Baud rate
The Baud rate for the serial interface is adjustable. The following Baud rates are available:
w 2400 Baud
w 4800 Baud
w 9600 Baud
w 19200 Baud
2.1.3 Parity
Parity detection is fixed to EVEN.
2.1.4 Addressing
KS 800 can be operated together with KS40, KS50, KS90, KS92, KS94 , KS98, KS4580,
DIGITAL 280/380 and PRO 96 and the ICS 90 and ITS 90 systems at the same bus. Decisive for instrument
selection is the address (2 bytes).
The KS 800 (0...99) address is adjusted via the “KS800 Engineering Tool” (general instrument settings Ä
communication Ä address).
2.2 Protocol layer 2
A fixed master/slave principle is used, whereby KS800 is always slave. Transmission control
(communication start and cancelation by EOT) is always by the master.
Two communication services are available:
q for data sending: SDA (Send Data with Acknowledge)
, acknowledged by KS 800
Data flow direction : master r KS 800
a)
Master
EOT <address> STX <data> ETX BCC

3.1 Message elements
In the following section, some expressions which shall be explained as follows are used:
Element
Description
Address of a participating unit, always 2 bytes long, adjustable on the instruments
<addr>
Data field composed of
a)
fields <identification> a. <value>, separated by character ‘=’
<daten>
b)
a series of successive <value> with several block accesses
identification field composed of
field <code> and
<identification> a)
b)
different selection criteria <selection>
Value of a datum, which is addressed with a key.
<value>
Addressing key of a datum, 2-digit, decimal number range, first digit also ‘B’.
<code>
further addressing field for selection of <function block no.> a. <function no.>
<selection>
Block Check Count. All characters between STX (exclusive) and ETX (inclusive) are
<BCC>
connected bytewisely by an EXOR function and output as 1 byte, always after ETX.
Rem.
A
B
C
D
E
F
Bem. A
Address field
The adress field can be transmitted only after ‘EOT’ and must be generated only by the master. It is two
bytes long. The address number range is 00 ... 99. If the transmitted address corresponds with the one
adjusted in the unit, the message is intended for this unit.
Different address settings are possible for COM1 and COM2.
Bem. B
Data field
The data field contains the parameters and data to be transmitted.
The equality sign is followed by the value of a datum (<valuex>). Several data are separated by a comma.
The data type depends on the access. The last value before ‘ETX’ ends without ‘,’.
With block read access with additional selection criteria, these criteria are specified only once. The data
follow without further identifications. Thus, the message structure becomes more compact.
Bem. C
Identification field
The identification field addesses a defined datum or a data area in the instrument. It consists of a code and of
an additional selection identification with some accesses.
With a data enquiry, the identification field contains information for KS92/94 which data the unit is expected
to send. This is always followed by the address field. In the reply, it is also specified for clear determination
of the datum, followed by the data field with separator „=“.
With data entry, STX is followed by the identification field for addressing the values to be specified.
Connection of the data field is by means of character „=“.
Bem. D
Code
The code identification is two bytes long and the value range is ASCII ‘00’...’99’ and ‘B2’... ‘B3’.

Addition selection criteria
In order to form a purposeful sub-set from the variety of data, additional selection criteria are defined:
q Function block number
A function block is addressed by a function block number. It is within ‘0’ and ‘250’ and is appended to
the code field by means of a comma.‘<code>,<function block no.>’
w

Function block number ranges:
0general data for the overall instrument
1 - 99fixed function blocks
100 - 250variable function blocks
q Function number
A function as a partial address of a function block is addressed with a function number. It is within ‘0’
and ‘99’ and is appended to the function block number by means of a comma.
‘<code>,<function block no.>,<function no.>’
w

Bem. F
Function number ranges:
0 - 99Functions
0Function General, Default, unless a no. is specified
Safety procedure
Correct transmission of a message is supported by two safety procedures:
w check of each message byte by formation of parity (1 bit per 7 data bits)
w Check by Block Check Count : safety section, which connects all characters of a message between STX
(excl.) and ETX (incl.) bytewisely by a logic XOR function; length 1 byte, follows always after ETX.

3.3 Data types
Data values are classified according to data types for transmission. Only characters which can be represented
in ASCII are permitted.
w
BCD
Floating Point number in BCD-ASCII format,
Range: -9999 ... -0.001, 0, 0.001 ... 9999
optional: negative polarity sign and decimal point permitted; exponent representation not permitted.
KS800 controllers with an accuracy of max. 4 digits. With received data, number of digits and decimal
point position are not fixed and depend on the FP resolution. The values are not rounded off.
Switch-off value for BCD data is : -32000
w
INT
positive integer number in ASCII format
Range: 0 ... 32767
Range with configuration words: 0000 ... 9999 (Ä page 14)
Exception: switch-off value ‘-32000’
w
ST1
Status, bit-oriented, 1 byte length
Range: 00H ... 3FH, transmitted: 40H...7FH
Only 6 bits for transmission of information can be used, i.e. bit 0...5 (LSB = bit 0). Bit 6 must always be
set to ‘1’, in order to avoid confusion with the control characters. Bit 7 contains the parity bit.
w

System dentifiction number (code 18)
For instrument identification, instrument type and software code number
3 0 , 1 2 3 4 5 6 7 8 , 1 2 3 4
can be read via code 18. The datum is composed of the following
sections:
Instrument type: (30 =KS800)
SW code number: (the last 8 digits)
Instrument version: 7th to 10th digit of 12NC (4 digits)
Diagnosis access: block 8x
For test purposes, an additional debug access which signals errors of the last write or read access is available.
Presently, reading is possible for:
w error number of last write access; 0 = no error
w position of the faulty datum during the last write access;
0 = no error or error in address
1 = first datum is faulty (also with single accesses)
n = nth datum is faulty (with block accesses)
w error number of last read access; 0 = no error
An independent memory for error messages is available for each interface COM1 and COM2. Presently, the
following error messages are defined:

5.1 Data structure
Due to the variety of information to be processed in KS800, logically related data and actions are grouped in
function blocks. A function block has input, output data, parameters and configuration data. For KS800, 25
function blocks are defined. They are all addressed via fixed block addresses (FB no.). Each block is also
divided into several functions. Functions are addressed via function numbers (Fct-no.). Function number 0
addresses function block-specific data.

6.2 Principles of the function block protocol
A function block comprises input and output data (process data) as well as parameter and configuration data.
It can be addressed via a block number. An allocated block type defines the relevant function.
The various access mechanisms are:
6.2.1 Single access
This access (code xx) can be used for reading or writing a single process value of a function. Single accesses
to parameter and configuration data are not possible.
Example: (message structure with specified data)
Transmission of the absolute output value (Yman) to controller channel 1.
Computer transmits data

6.2.2 Block access (tens block)
This access (code x0) can be used for reading max. nine process values of a function.
Example: (message structure with data request)
Reading of set-points (Wnvol and Wvol) from controller channel 3 .
Computer requests:

6.2.3 Block access (overall block)
This access can be used for reading and writing all parameter (code B2) and configuration data (code B3) of
a function. The following conditions are applicable for this access:
w For writing data with ‘Code B3’, the unit must be switched to configuration mode (Ä see page 14
‘OpMod’). All new configuration data and parameters entered are only effective, when the unit was
switched back to on-line.
w All data of a message must be defined, omissions are not permissible.
w If all parts of a message in the instrument are unused (HW and SW options), the complete message
must be transmitted nevertheless. Checking the non-available data is omitted.
w With faulty block write accesses, the following rule is applicable: A message is answered with NAK, if
min. one datum is faulty. Already valid values are stored.
w If the function number is omitted, function 0 (general) is addressed.
The general structure of a message with block accesses with code B2/B3 is shown below. The exact message
structure (between STX and ETX) for the individual functions can be found below the relevant code table.
