Abstract
A hard-wired circuit (25) is provided for controlling or for monitoring a plant or process (12). The circuit incorporates means (14) to sense the current state of the process, an input encoder (16) to generate multi-digit binary coded signals representing that sensed state, and an output encoder (18) to generate multi-digit binary output coded signals corresponding to the signals from the input encoder (16), which output signals can be used to control process or plant actuators. Both the input encoder (16) and the output encoder (18) may be PROMs. A complement modulator (20) activated by an oscillator (24) may be used to provide dynamic output signals; and by means of appropriate comparators (26, 38) and watchdogs (28, 40) the input and output coded signals may be verified.
