MICROMASTER has an integrated technological controller (PID controller, enabled
via P2200). This can be used to process basic higher-level control functions. These
typically include:
Pressure control for extruders
Water level control for pump drives
Temperature control for fan drives
And similar control tasks
The technological setpoints and actual values can be entered via the PID
motorized potentiometer (PID-MOP), PID fixed setpoint (PID-FF), analog input
(ADC) 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.
3-36).
