Configuring S7400F/FH with ET200M & SM300 in Simatic Manager

Hello Arian-A;

Time yo show us a screenshot of your hardware configuration  I guess.

To set up a redundant ET 200M station  you need a S7'400H system (2 redundant CPUs on a split rack  for example), then you should be able to drop 2 IM 153-2 in your ET 200M redundant station.

Physically  you have to use specialized hardware jn the redundant ET 200M (even though you will not configure them in HWConfig): you must create the equivalent of a CPU backplane for all the modules in the ET 200M, using active bus modules, one IM/IM bus modules plus up to 6 active bus modules for your I/O cards, all 12 of them. And the regular S7-300 rack will not work with active bus modules, so firz redundant ET 200M you need a special redundancy rack.

This is all described in these ET 200M manual extracts:

And the video below shows how a redundant ET 200M is introduced in the St-400H Hardware configuration (around 5:30).

Hope this helps,

Hello Arian-A;

Sorry to announce this to you, but in your screenshot you have correctly set up a redundant ET 200M to work with a S7-400H system.

Whe you want to configure a redundant ET 200M with a S7-400H system, in HWConfig you only insert one IM 153-2 (HF, if you want), connected  both S7-400 Profibus interfaces. This is what you have in your configuration, and that is what you needed to do. There is no need for a second IM 153-2 in your configuration.

I suggested you look at the Youtube video earlier, specifically at time setting 5:30, to see how the Youtube programmer did it. You seem to have omitted to examine this, so I have attached a screenshot from that video, beilow.

I am also attaching a pdf print of 2 sections of the following manual "Configuration of Redundant I/O Modules in SIMATIC PCS 7". I have included only the sections fefering to the setup of redundant IM 15-32 modules, so you do not confuse this with the PCS 7 redundant I/O issues. 

The isuue with the part number for the redundancy rail  did not exist with the versions of PCS 7 I worked with, I do not believe it is something that could lead to a problem.

Hope this helps clarifying things,

Daniel Chartier
