Hello, I suggest reading chapter 13 "Using I/Os in S7–400H " of the following manual: SIMATIC Fault-tolerant systems S7-400H and a sample project embedded in STEP 7 for redundant I/O. I hope this helps Hamid Hosseini

Configuration of Redundant I/O Modules in SIMATIC PCS 7 You can use the above PCS7 document to understand more how redundant IOs work (from hardware perspective). For the software, please read carefully chapter 4 (Function Mechanism). Best regards, H-H
