METHOD AND DEVICE FOR MONITORING INFORMATION TRANSMISSION BETWEEN THE CENTRAL UNIT OF A PROGRAMMABLE COMPUTER AND THE INPUT/OUTPUT CIRCUITS CONNECTED TO THE SENSORS AND/OR ACTUATORS OF THE CONTROLLED PROCESS

摘要

The device according to the invention comprises on input/output cards (4) a plurality of electronic circuits (300, 400, 500) forming the logic interfaces between the connection bus with the central unit on one hand and the sensors or actuators (9, 7) connected to each track on the other hand. This device further comprises means for monitoring the good transmissions of logic signals between the central unit and the input/output cards (4). The invention applies particularly to programmable computers.
