Hello, Perhaps one of the following points might solve the problem: 1-Check the Back plane between CPU and Rack . 2-Check the connections. 3-Post the diagnostic buffer of the CPU. 4-Perform Master reset for the CPU. 5-Upgrade the firmware of the CPU. Where can you find the latest updates of the operating systems for the CPUs S7-31x, IM15x and BM147? 6-Kindly have a look at the attached file.
