Air-conditioning system

An air-conditioning system comprising a general-purpose device controller configured to control a general-purpose device connected via one of a general-purpose transmission line and an input/output signal line and an air-conditioning facility connected via a dedicated transmission line, wherein

• the general-purpose device controller includes a processing configuration unit configured to receive a first signal corresponding to the air-conditioning facility and a second signal corresponding to the general-purpose device, and transmit a control signal which controls the air-conditioning facility and the general-purpose device based on the first signal and the second signal,
• the processing configuration unit:
• is configured to designate the air-conditioning facility which is a first control target, with a management address which is included in the first signal and designates the air-conditioning facility,
• is configured to designate the general-purpose device which is a second control target, with an input/output port number which is included in the second signal and designates the general-purpose device, and
• is configured to transmit the control signal which performs ganged control of the first control target and the second control target,
• the general-purpose device controller further includes an interface configuration unit configured to relay various signals transmitted and received between the air-conditioning facility and the processing configuration unit,
• in the interface configuration unit, a first predetermined cycle is set as a timing of collecting the first signal and a second predetermined cycle longer than the first predetermined cycle is set as a timing of supplying the collected first signal to the processing configuration unit, and
• when the first signal is requested to the air-conditioning facility and is returned, the interface configuration unit collects the first signal determined to be collected based on the management address of the first signals flowing on the dedicated transmission line every first predetermined cycle, and
• the interface configuration unit supplies the collected first signal to the processing configuration unit every second predetermined cycle.
