I have a case of same value of signal for two days
First of all the energy of Apinode was off, then the refresh was automatically, its ok
The problem: the value was the same for two days.
I checked the communication is OK
I checked OPC client, PI DA is OK
I checked ICU, apparently was ok, because It was showed Check . But I reset and Finally the all signal refresh
Somebody could how to help us? I think is important to configurate the ICU.
