I built a SCADA using IWS v8.1 InduSoft Web Studio. I've added several trending screens which started out running fine. Over the course of several weeks, the trends work rather randomly. Some points start and stop at random times. Some just stopped on their own, no rhyme or reason why... I was told that it might be because of corrupt historical files so I deleted them and over time, same results.
I an using the proprietary setting with a 1 second trigger. I had started out using both the 1 second trigger and the Save on Tag Change option with a deadband. Either setup seems to get the same sporadic result.
Anyone else experience this?
