Closed-loop PID control
MICROMASTER has a technology controller (PID controller, enabled using
P2200); this can be used to execute basic, higher-level control functions.
The technological setpoints and actual values can be entered via the PID
motorized potentiometer (PID-MOP), PID fixed setpoint (PID-FF), analog inputs
(ADC, ADC2) or via serial interfaces (USS on BOP link, USS on COM link, CB on
COM link) (refer to the example). The appropriate parameterization of the BICO
parameter defines which setpoints or actual values are to be used (refer to Fig.
3-54).
