SPC (Setpoint Control)Then the computer was used for setting optimum setpoints on individual controllers.

DDC (Direct Digital Control)And then a single computer is used to executes control computations for controlling multiple control loops.

LoggerAt the initial stage, a computer was used as a logger only for the monitoring and logging.
