Abstract

PURPOSE:To prevent an operation error by providing a discrimination information memory for storing the information by which the kind of signal is discriminated, on a process input/output device. CONSTITUTION:A discrimination information memory 8 constituted of an ROM, for storing the information which discriminates the kind of signal to be inputted and outputted between a process input/output unit 3 and an external process is provided on the unit 3 which transfers a control data to the process, or inputs a data from the process and inputs the data to an electronic computer 1. Also, a readout instruction of the memory 8 is provided on the kind of instruction which is transferred to a control units 2 from the computer 1. In case the computer 1 outputs a data to the process or inputs a data from the process, it is prevented from inputting or outputting an erroneous data, by inserting a signal which is the same as information stored in the memory 8, into an instruction word, outputting it, reading out the corresponding contents of the memory 8, and collating whether both of them coincide or not.
