PID_INT Controller function philosophy

[JRDARJI]

Dear all,

looking for some sort of support or views on the PID_INT controller functional philosophy. During switching from Auto to manual mode operation of the controller, what the controller output will be and how will it behave. please share detailed functional description of the controller along with the parameters configuration and its usage would be highly appreciable.

Thanks,

Hi..

Normally, At instance of switchover of Auto to manual mode,  PID output at that moment is read and transfererred to Manual setpoint of PID to keep PID output at same value, make switchover a bumpless avoid bumps in outputs and control device  

However this can be again based on the process we are controlling.

Regards
