LOAD CONTROL SYSTEM USING MULTIPLEX TRANSMISSION

摘要

PURPOSE:To obtain a system in which a load device is forcibly controlled or forcible control is inhibited by having only to connect a controller externally without a control program for the load control system and a control table written in a load controller are not rewritten in the load control system using multiplex transmission. CONSTITUTION:The load control system is a system utilizing multiplex transmission by connecting plural loads and operation switches or the like as terminals 50 to a load controller 30 via a multiplex transmission line 41. A forced controller A is interposed to the multiplex transmission line 41 toward the load controller 30, and the forced controller A is used to decode and process a control signal sent from the load controller 30 or a control command signal sent from the terminals 50 thereby driving a specific load or inhibiting the drive.
