Problems solved by technology

[0003] Currently, when creating a PLC setting file for a supervisory control system, it is necessary to take into account the correspondence between the PLC and the control devices so that the PLC can be correctly controlled even if the number of control devices increases. It takes a lot of man-hours to generate PLC setting files simultaneously

Abstract

A programmable logic controller setting file generation assistance device, having a programmable logic controller configuration calculation unit (38) for: determining whether or not a programmable logic controller configuration, the input of which has been received by an instrument configuration input unit (32), is compatible with a rule on the basis of specification information about a programmable logic controller, specification information about a control instrument, and specification information about a network; outputting the programmable logic controller configuration, the input of which has been received by the instrument configuration input unit (32), in cases in which the programmable logic controller configuration is compatible; and calculating and outputting a programmable logic controller configuration modified so as to be compatible with the rule in cases in which the programmable logic controller configuration is not compatible. The programmable logic controller setting file generation assistance device also has a programmable logic controller setting file output unit (40) for generating a programmable logic controller setting file pertaining to a programmable logic controller configuration selected from among programmable logic controller configurations displayed on a display device.

Description

technical field [0001] The present invention relates to a programmable logic controller setting file generation assisting device for assisting creation of a setting file downloaded to a programmable logic controller. Background technique [0002] In the supervisory control system, the supervisory computer called SCADA (Supervisory Control And Data Acquisition) gives operation instructions to the programmable logic controller, and each control object as the control object is controlled by the control program stored in the programmable logic controller. The movement of the instrument is controlled. In order for the PLC to control the operation of each control device, it is necessary to store a PLC setting file defining connection information between the PLC and each control device in the PLC. [0003] Currently, when creating a PLC setting file for a supervisory control system, it is necessary to take into account the correspondence between the PLC and the control devices in ...
