ABSTRACT:
A digital controller includes a microprocessor for receiving a signal indicating a process variable from a process and calculating a manipulated variable in accordance with a predetermined algorithm in order to cause the manipulated variable signal to follow a desired setpoint variable. An operation data output system delivers an output signal to the process which holds the operation output value from the microprocessor. The controller also has on an electronic indicator for displaying the process variable, the setpoint variable, and the manipulated variable, and a driver for receiving the process variable signal and the setpoint variable to drive the electronic indicator. The driver further receives the manipulated variable from the operation data output system for driving the electronic indicator, whereby the controller is capable of displaying the manipulated variable on the electronic indicator should the microprocessor fail.
