3.2 Detecting the configuration variant by means of the IM 153-2

3.2 Detecting the configuration variant by means of the IM 153-2
During start-up, the IM 153-2 automatically detects which structure variant (ET 200M or
DP/PA-link or Y-link) it is being used in. The IM 153 2 determines its functionality in
accordance with this.
Note
The following structure variants ("mixed structures") are not permissible:
• Input / output modules and coupler modules in one structure
• Bus modules BM 2 x 40 / BM 1 x 80 and BM DP/PA / BM Y coupler in one structure

Configuration possibilities for PROFIBUS DP

3.3.1

Distributed I/O with IM 153-1

The IM 153-1 is the interface module of the ET 200M for standard applications.
Sample Configuration
The following figure shows an example of an ET 200M with IM 153-1 and 4 I/O modules of
the S7-300 as a distributed I/O to a CPU 315-2 DP as a S7 DP master.
