Hi Prakash_Chennai, This fault is due to DP slaves which does not get initialised/configured during PLC startup. U should again perform Master-slave changeover by putting PLC0 in stop mode. Now if CPU1 is without external fault, then the problem is with monitoring times 1. Finished message from modules 2. Transfer of parameters to modules[CPU properties-Startup. |
