Siemens SIMATIC PCS 7 Operating Instructions

Sample configuration of a redundant DP-master system and IM 650
The following figure shows an example of a redundant configuration. For the AS 410H, the
ET 200PA SMART is a single-channel switched (distributed) I/O. A detailed description of H-

http://
support.automation.siemens.com/WW/view/en/74736834)".

Compatible versions
If you use the ET 200PA SMART in a redundant configuration, you must use compatible
versions for the two IM 650 modules.
Compatible versions of the IM 650 interface modules can be swapped during "Module
replacement in runtime" without switching off the I/O modules.
For more information, refer to section "Arrangement of the modules for the function "Change
During Operation" and / or "Redundancy" (Page 20)".
Note
The functions that can be used are limited to the respective lower order number or the earlier
version.
AS 410H as DP master
You require PCS 7 as of V8.1
DP master 1 and DP master 2 run the same user program. Both have the same parameter
assignment and configuration for the IM 650 interface modules.
