<p>PURPOSE:To ensure the stable and sure check of a programmable controller PC with a simple operation by applying a check signal to the checking subject PC from a control means via a connection means that can be freely attached and detached for decision of the checking result and then printing out this result. CONSTITUTION:A worker puts a work 21 serving as a PC on a contact pin group 23 to check the PC and secures a sure electrical connection between the group 23 and the input/output terminal of the work 21 via a fixture 22. Then, an FA computer 25 sends a self-diagnostic start command to the work 21 via a communication port 44 when a key 26 is operated. The work 21 decodes the received command and performs a self-diagnosis. Then, the work 21 sends the checking result received from a communication port 37 to the computer 25. The computer 25 decodes the received data to decide the validity or invalidity of this data to show this deciding result on a CRT 27. If the validity of the data is confirmed, the data is printed by a check totalizing printer 29. If not, a defect occurrence sheet is printed by a compact printer 28 and stuck onto the work 21.</p> |
