Sample Configuration of a Redundant DP Master System and the IM 153-2
Figure 3-6 shows an example of a configuration on an S7-400H. For the S7-400H,
the ET 200M is a single-channel switched (distributed) I/O module. You will find a
detailed description of H systems in the S7-400H Programmable Controller,
Introduction to the System Manual.

Identical Versions
If you use the ET 200M in a redundant configuration, you must use compatible
versions of the IM 153-2 and IM 153-2 FO.
You can replace compatible versions of the IM 153-2/IM 153-2 FO in the case of
configuration modification in RUN without switching off the I/Os. Compatible
versions are:
IM 153-2BA00 and IM 153-2AA02, as of version 05
IM 153-2BB00 and IM 153-2AB01, as of version 04.
Note: The usable range of functions is limited to the lower order number and lower
version number in each case.
S7-400H as DP master
You need STEP 7 (V 5.0 or higher) and the software package
SIMATIC S7 H Systems to configure the S7-400H system.
The DP master 1 and DP master 2:
Process the same user program.
Have the same parameter assignment and configuration for the IM 153-2.
