Enable gain scheduling on existing PIDCONA in AC450
Hi!
We have several control loops which suffer due to shifting operational domains.
Due to this shifting, which introduces nonlinearities, I would like to enable gain scheduling for a selection of these controllers.
Since the controllers are operational, I need to enable the gain scheduling feature while online.
However, when trying to do this by using the MV command on the call parameter C6 of the PIDCONA block I get the message "NOT CHANGEABLE; TYPE <, >, ! or CR".
Example for a chosen PIDCONA: "#mv PC35.5.1.100.110:C6" returns the message mentioned above.
This is where I don't get any further.
Is there another way to enable gain scheduling on existing PIDCONAs while online?
Best regards,
Andy

Unfortunately you need to remove the PC element PIDCONA and add it again with the right call parameters selected (C1 -C6).
It can not be changed online in any other way.
