PROBLEM TO BE SOLVED: To simplify handling of a wiring system for independently sending out instruction signals or the like from a high order control system to be a base point to a plurality of low order control systems, and to easily perform wiring work, maintenance work, or the like.SOLUTION: Common relay boards 208A-208D of the almost same structure are disposed at appropriate positions (for instance, four corners) of a set board 210, and a performance control board 152 and the plurality (for instance, four pieces) of common relay boards 208A-208D are connected in a daisy chain manner. In addition, by storing an intrinsic address in the common relay boards 208A-208D and making it possible to specify a device to be controlled on the basis of address information from the performance control board 152, the device to be controlled disposed most nearby is made connectable to the respective common relay boards 208A-208D, handling of harnesses 220, 222, and 224 is simplified, and wiring work and maintenance work can be facilitated. |
