FACILITY MANAGEMENT SYSTEM, SUBORDINATE CONTROLLER, AND COMMUNICATION DIAGNOSTIC METHOD IN SUBORDINATE CONTROLLER

摘要

PROBLEM TO BE SOLVED: To provide a facility management system that can confirm whether control information to be received from superordinate controllers is validly received or not in subordinate controllers.;SOLUTION: A superordinate controller (20) comprises a transmitting unit (21) which transmits control information to at least one subordinate controller (30). The control information controls functions of the subordinate controller (30). The subordinate controller (30) comprises: a receiving unit (31) which receives the control information transmitted from a plurality of superordinate controllers (20); a diagnosis unit (34) which determines whether the receiving unit (31) has redundantly received control information for controlling the same function from a plurality of superordinate controllers (20); and an alarm output control unit (35) which outputs alarm information when the diagnosis unit (34) has determined that the receiving unit (31) has redundantly received the control information for controlling the same function from the plurality of superordinate controllers (20).;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2020,JPO&INPIT
