Commissioning With Manual Pid Parameters V1 - Siemens SIMATIC S7-1200 Function Manual

Procedure
Proceed as follows to carry out "fine tuning":
1. Select the entry "Fine tuning" in the "Tuning mode" drop-down list.
2. Click the "Start" icon.
– An online connection will be established.
– Value recording is started.
– The process of fine tuning is started.
– The "Status" field displays the current steps and any errors that may have occurred.
Result
The PID parameters will have been optimized if fine tuning has been executed without
errors. PID_3Step changes to automatic mode and uses the optimized parameters. The
optimized PID parameters will be retained during power OFF and a restart of the CPU.
If errors occurred during fine tuning, PID_3Step will change to "inactive" mode.

The progress bar indicates the progress of the current step.
Note
Click the "Stop" icon in the "Tuning mode" group when the progress bar has reached
100% and it is to be assumed the controller tuning function is blocked. Check the
configuration of the technology object and, if necessary, restart controller tuning.
