3.3 Configuration possibilities for PROFIBUS DP
ET 200M

3.3.3 Configurable FM in a configuration with IM 153-2
Example configuration with IM 153-2 and FM
The following figure shows an example of an ET 200M with IM 153-2 and in each case two
SM and two FM of the S7-300 I/O modules. Via the IM 153-2 the S7 DP master or the
PD / OP can communicate directly with the configured FM (the thick line represents the
communication path). Configurable FM are, for example, the FM 353 / 354 / 355.
The following S7 functions are supported by the IM 153-2:
● Assigning FM parameters via the DP mater CPU
● Commissioning and diagnosing the FM via a PD / PC
● Operating and monitoring the FM via an OP
Refer to the appendix "Compatibilities between the versions of IM 153-2 / -2 FO (Page 243)"
to see if the DP master you are using and the FM also comply with this functionality for
distributed FM.
