PID_Compact

Hello guys, so i have a S7 1212C DC/DC/DC and i have written a program in SCL with a PID_Compact and some controll software to a VFD. When i try to simulate the PID the input value never changes. I have it configured to Input_PER and i have the analogic tag correctly inserted. I was wondering if this has something to do with the simulation.

Im using TIA Portal v16 Update 4 if that helps

Thanks in advance

Hello chourico;

Have a look at the pdf document accompanying this Application Note:

https://support.industry.siemens.com/cs/ww/en/view/100746401

This quote should be interesting to you:

"4.3 CPU simulation with PLCSIM

You can simulate the technology object "PID_Compact" V2.x for CPU S7-1500 with PLCSIM. The simulation of PID_Compact V2.x with PLCSIM for CPU S7-1200 is not supported.

Hope this helps,

Damn, wierd but it´s TIA haha. Thanks for the help.

Thanks for the help
