Communication blocks Siemens

Область применения



WirelessHART communication blocks are used where SIMATIC automation systems communicate with WirelessHART devices via the IE/WSN-PA Link gateway.

Обзор



The WirelessHART communication blocks implement the communication between S7/PCS 7 automation systems and WirelessHART field devices. They communicate via the IE/WSN-PA Link using the Modbus TCP/IP protocol. Configuration is made easy by virtue of prefabricated communication building blocks. Symbols and face plates are included in the delivery for use with WinCC.

Функции



The function blocks cyclically communicate with the IE/WSN-PA Link via Modbus TCP/IP. Process values of WirelessHART devices as well as their status are read and made available at the building block outputs. Furthermore, selected status information of the IE/WSN-PA Link is also made available at another building block. This information includes connection status, condition of the wireless network and other diagnostics.

Precondition of the usage of these communication blocks is a TCP/IP connection, engineered in NetPro in the Engineering Station of Simatic PCS 7. Currently this requires a CP343 or a CP443-1.

Конфигурация



The standard S7 or PCS7 engineering tools CFC, KOP, FUP can be used for communication block engineering. Connection planning is done in NetPro. A configuration example for configuring the IE/WSN-PA Link makes it easy to assign the WirelessHART devices to the communication blocks which need to be engineered.

Особенности



A library, which can be installed, offers pre-fabricated blocks and hence an easy way to integrate WirelessHART devices into the SIMATIC automation world.

Simple configuration thanks to:

  • Prefabricated function blocks for IE/WSN-PA Link and WirelessHART devices
  • SIMATIC PCS 7 OS or SIMATIC WinCC symbols and face plates are included
  • Planning help for IE/WSN-PA Link in line with function blocks
  • Output of quality codes for respective process values
  • Analysis of IE/WSN-PA Link diagnostic information
