Hello Everyone,
I am using WAGO 750-8212 PLC with beijer HMI X2 pro. I lost communication in 2 way one is through power on and another time during machine running which is sometime only. I tried with increasing scan cycle and all nothing helps. If I turned off the machine and then turned on again then i have this issue and again i turned off plc and turned ON again PLC meanwhile switch off HMI and ON again then this issue diappear. When this issue happened i have the problem in PLC called Watchdog time of the local bus has expired.Also I want to mention when the issue happened there was version mismatch between PLC V4 and HMI V5.
