S7-400 CPU416 Redundant System

[aabcam75]

Any one can help me how to configure the redundant system of S700-400 CPU 416 and 10 unit of ET200M run via profibus.

Thank you.

Hello aabcam75;

Configuring ET200M modules as slaves to a S7-416-2DP is straightforward, using Step 7's Hardware Config. Use the Profibus-DP library to select the IM153 comm. module you are using, bring it on the Profibus line, give it a Profibus address and complete with the S7-300 I/O modules you will need. Then use the S7 addresses selected by the Hardware Config editor to access the I/O modules from your program.
What makes your request special is your use of the word "redundant"; please specify what you mean by that term, as the CPU 416 is not a redundant processor in the Siemens family (only S7-414H and S7-417H are considered redundant). Do you intend to implement redundancy at the fieldbus level, and if so, in what circumstances. Then we can talk about the How.
Hope this helps,
