Hello, there are for all technology objects the "PIDSelfTune.SUT.State" and "PIDSelfTune.TIR.State" in the instance DB. When it is 9900, the pre-/fine tuning was successful. You will get the best PID parameters when you are running the pre-tuning first and then the fine tuning. Please have a look at the following links: SIMATIC S7-1200, S7-1500 PID control |
