FACILITY CONTROL SYSTEM

PROBLEM TO BE SOLVED: To provide a facility control system that can restrain apparatus cost from becoming high, by restraining reduction in operation efficiency of a facility apparatus, without maximally stopping operation of the facility apparatus, even when abnormality is caused in a first layer computer for commanding an apparatus operation command on the facility apparatus to an apparatus controller.SOLUTION: This facility control system includes a selecting means for selecting whether a first layer program executed by the first layer computer is executed by a second layer computer by artificial operation, when the abnormality is caused in the first layer computer for executing the first layer program for commanding an apparatus operation command to the apparatus controller in response to a work command, includes a substitutive command output means for outputting a substitutive command in response to selection information selected by the selecting means, and is constituted so that the second layer computer executes the first layer program executed by the first layer computer of causing the abnormality based on the substitutive command output by the substitutive command output means.
