Enable gain scheduling on existing PIDCONA in AC450
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 PC18.104.22.168.110: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?
