Hello Rajkiran; In the suggested links found in last years thread, you have this list of failsafe equiment, including failsafe CPUs: http://support.automation.siemens.com/WW/view/en/27832836 Any one can support the communication interfaces you request (with extra CPs) and all can support the number of IOs you request, either on the PLC rack or through Profibus-DP. The attachment illustrates this. So select one you are familiar with for the standard part of the program, and read the manuals for failsafe programming, such as: SIMATIC Industrial Software Safety Engineering in SIMATIC S7 You will need to determine which of these IOs are failsafe (for the failsafe program), this will have great impact on your selection of modules and your programming. Hope this helps, Daniel Chartier |
