Don't really understand - what does the PID at the moment? - PID controller pulses the Output_UP. PID controller is in normal run. See the attachments for pv scaling and PID parameters. AttachmentPID parameters&scaling.zip (97 Downloads) |

Yes, the PID controller is used with the inverted control logic. I attach screenshots of the Parameter view and call of the PID controller. The PID controller is called in OB31, with a cycle of 100ms. I partially solved this problem by adding an additional condition after calling the PID controller (highlighted in red in the screenshot), thereby "jumps" on ScaledFeedback are not transmitted to the WinCC Server, and does not appear in the trends on the WinCC Clients.
