PROBLEM TO BE SOLVED: To provide a testing device and a testing method for automatically testing the validity of the process input/output signals of a board to be tested to which a CPU with a built-in microcomputer is mounted. SOLUTION: By performing constitution by a reference board 5 for inputting and outputting reference value signals corresponding to the process input/output signals of the board 6 to be tested for inputting and outputting process signals for which a pressure, a flow rate and a temperature, etc., are converted to electric signals so as to control a plant and a controller 15 for judging the validity of the process input/output signals by comparing the reference value signals with the process input/output signals and registering and editing a judged result, automatic testing is made possible. |
