<p><P>PROBLEM TO BE SOLVED: To provide an operation panel at low costs by making a constitution with a high degree of freedom of distribution of a parallel signal line and a serial signal line between the operation panel and a control device for a general purpose to commonly use the operation panel for various equipment. <P>SOLUTION: An operation panel 30 has a switch part 16 comprising a plurality of switches actuating equipment, and is connected to a PLC 40 controlling an actuation of the equipment. The operation panel 30 comprises: a parallel signal line 42 for parallely connecting signals of the switch part 16 to the PLC 40; a communication control part 11 for converting the parallel signals of the switch part 16 to be connected into serial signals; serial signal lines 31, 41 for connecting the communication control part 11 and the PLC 40; and a switching part 14b for switching some of the signals of the switch part 16 connectable to any of the parallel signal line 42 and the communication control part 11. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
