Description

  The present invention relates to an engineering device connected to a host controller that manages and controls a control device via a communication line to which a predetermined protocol is applied.

  As a monitoring system that monitors and controls multiple field control devices in a building, using different open networks such as BACnet (Building Automation and Control networking protocol), different manufacturers such as air conditioning equipment, lighting equipment, electrical equipment, and disaster prevention equipment Multi-vendor compatible systems that connect these systems and perform monitoring and control have become widespread.

  In constructing a monitoring system corresponding to this BACnet, it has become established in Japan as a CSV file in which object information of a control device corresponding to the BACnet specification is separated in advance from each vendor in advance. Then, based on the CSV file obtained by the engineering device, a JOB file in which management information such as control device information managed by the monitoring device, monitoring point information, and object information is recorded is created. Further, the engineering device creates an operation file for operating the host controller managed by the monitoring device based on the created JOB file, and downloads it to the corresponding host controller.

  For example, the engineering apparatus according to Patent Document 1 generates an instance for each object by taking in a CSV file in which object specifications conforming to BACnet are described in CSV format and referring to object parameters prepared in advance for the object specifications. Then, object implementation information is generated from the instance.
