Abstract

PURPOSE: To obtain a trouble discriminating method having a simple constitution by applying standard input to an input point which is used for process control and considered to be basic and obtaining the output response of analogue calculation element in each stage and judging operation characteristics.
CONSTITUTION: A process control apparatus 1 consists of arithmetic amplifying circuits 1-1 - 1-n connected in multistage, and as its input 11, process controlling input signal 21 or trouble diagnosing standard input signal 22 is provided through a switch 2. In diagnosis, the voltage value E stored in the data memory 31 of a microcomputer 3 is added as standard signal, and the output response of each arithmetic amplifying circuit is selected through an input multiplexor 6 and taken in as digital signals. Thus, troubles are discriminated from the comparison with the response signal in normal state.
