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.
