from the HMI department...
Problem in Citect( redundancy HMI)
Two systems are used as Primary and standby system (redundant HMI).
All things are right only sometimes (once per 40-45 seconds) I have #COM in each tag for 2 or 3 seconds and then the data are shown valid.
I checked all setting and they are OK.
Of course when primary system is shutdown, the tags of stand by system became #COM and after about 4-5 minutes, the tags take valid data and HMI shows correct data
