Trend Date/Variable
I have the following problems with the trend display:
The date/time in the PLC is set to the current date, but the trend time is 01/01/1970.
I tried deleting and re-creating the trend manager and trend controller, but still it doesn't work. By chance, it works after the second attempt.
Why? I don't understand.😂
The second problem:
The variables stored in the FB or global VAT could not be assigned to the curve. The only variables that could be connected to the trend controller are FC/Prg variables.
Thank you fpr your reply
