3.3 Configuration possibilities for PROFIBUS DP
3.3.2 Passing on parameter assignment data from the PD / PC with IM 153-2
Example configuration with IM 153-2 and a HART module
You can use HART modules in the ET 200M In this application, the ET 200M HART is a
master for HART slaves (intelligent field devices) in the Ex area. The IM 153-2 passes on
parameter assignment data from the PD / PC via the HART analog input module to the
intelligent field devices and back again (the thick line indicates the communication path). For
a detailed description, please refer to "S7-300 Automation Systems, ET 200M Ex I/O
Modules (http://support.automation.siemens.com/WW/view/en/1096709)" in the device
manual.
