<P>PROBLEM TO BE SOLVED: To provide a controller capable of outputting various monitor signals with high degrees of freedom without providing an exclusive monitor signal terminal. <P>SOLUTION: The controller 20 controls a control object based on a signal to be transmitted via a communication line S, and includes: a mode switching part 20a which shifts from a control mode for controlling the control object to an inspection mode when predetermined signal input is detected; and a communication part 20b which changes a signal form of the signal to be transmitted or received via the communication line from a first signal form to be used in the control mode to a second signal form different from the first signal form to perform communication when the controller shifts to the inspection mode by the mode switching part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
