It is important to follow the instructions supplied with the device, in particular: . . . • Avoid touching the connector pins (ESD precautions) • Push the module firmly into position (1.5 mm) and check that it is securely in place so that the fine contact pins interlock properly. 2 1 Plug-in unit 1 4 2 Device base 3 . . . 9281z02 3 PXA30-RS… extension module (always to the right) 4 Other extension modules (commonly PXA30-N) Note: The PXA30-T and PXA30-NT also have a D-sub 9-pin connector. However, this is used for the modem connection to DESIGO. 3/8 Siemens Building Technologies PXA30-RS, PXA30-RS1, PXA30-RS2 – Extension modules for RS232 and RS485 CM1N9281en_02 30.03.2007 Engineering Engineering is carried out with the DESIGO TOOLSET (DTS): • The project is created with SYSTEM DESIGN (DTS-SD) • The completed project is exported to DTS-PX Development environment • PX SCL is available for free programming on PXC00-U, PXC64-U and PXC128-U modules fitted with the PXA30-RS… extension module • The PXA30-RS… extension modules do not support software tools for development of custom applications. These individual applications must be developed on the PXE-CRS platform. Commissioning on the BACnet side Commissioning on the automation side (BACnet) is carried out with DESIGO TOOLSET (DTS). • An address is assigned to the device • The application (for the coordination of the HVAC functions at the automation level) and the mapping tables for the field level are downloaded. Addressing Node setup via DESIGO TOOLSET Third-party commissioning Third-party systems are commissioned with the third-party manufacturer’s commissioning tool. Siemens Building Technologies provides a tool, PX OPEN Monitor, for the monitoring and analysis of data traffic on the third-party bus. The connector for this tool is on the front of the automation station. Disposal The device includes electrical and electronic components and must not be disposed of as domestic waste. Current local legislation must be observed. 4/8 Siemens Building Technologies PXA30-RS, PXA30-RS1, PXA30-RS2 – Extension modules for RS232 and RS485 CM1N9281en_02 30.03.2007 . . . . .
