The Redundancy Fault on the CPU, if it is about the REDF LED being on, that is likely due to a mismatch between DP configuration and physical representation. This can be more explained in the Fault Tolerant S7-400 Manual (http://support.automation.siemens.com/WW/view/en/82478488) Not actual CPU to CPU redundancy... _____________________________ This REDF light will not affect the OS and AS communication. What is the history here? Did this function before and not stopped working? Is this initial setup? Phantom is right, we need more information (download logs, screen captures..etc)...
