WinCC probs

[sparkotronic 0]

Hi all, I'm trying to put in a mod on a wincc project to allow PID adjustment. My problem is that the reset time is in "T#20m" format and I can't seem to get my wincc project to display it. The options on the input/output field don't seem to allow for this format, or am I being dense again! Am I able to change it into a wincc friendly format to allow me to use it. Thanks in advance.

WinCC or WinCC Flexible ?

I don't know! I'll need to check on monday, can you do it with one and not the other?

It is WinCC Flexible

Use DINT for the type of the tag in WinCC Flexible, despite that it is a TIME in the the S7 program. It will then show as milliseconds in WinCC Flex RT. If milliseconds is too fine, you can apply scaling in the tag in WinCC Flex. To get it to show as seconds for example simply specify that when PLC=1000, then HMI=1.

wow, it doesn't mention that in the manual! It worked a treat, thanks a million. Once I work out the best way to tune PID's the job will be a winner! Colin
