hello,
I'm using wincc 7.0 and it is working fine, except for the trending. The trending is only showing values up to 7 days. The client wants a trend history of a least 1 month.
How can i change this.

Thanks.
 
Logging

Hello dmkar,

I've no WinCC at hand, but I remenber that yoiu should go to TagLogging -> SlowLogging. In properties, you can set size of the historical database, maximum number of days amd toher adjustments. Set minimun days to 31 and make the allowed space bigger.

Best regards,
Kelkoon
