Abstract

In order to create a system configuration chart indicating the configuration of a constructed PLC system, a PLC system construction assistance program causes a computing terminal to function as the following functional units: an image acquisition unit (21) that acquires image data (400) of an image of the PLC system; a system configuration identification unit (22) that creates system configuration information (700) including the arrangement information (500) and the selection unit information (600); a system configuration diagram generation unit (24) that creates a system configuration diagram (800) on the basis of the system configuration information (700); and a system configuration chart editing unit (25) that performs display processing for displaying the system configuration chart (800) on a display unit.

Description

technical field [0001] The present invention relates to a PLC system construction assistant program, an arithmetic terminal-readable storage medium, and a PLC system construction assistant for creating a structure diagram of a PLC system for an actually constructed programmable logic controller (hereinafter, simply referred to as "PLC") system device. Background technique [0002] A PLC system used as a control device of an industrial machine or the like is constructed by combining desired units. The units that construct the PLC system include, for example, a power supply unit that is a power supply source, a CPU unit that controls the PLC system, an input unit that inputs signals from switches, sensors, etc. installed in equipment, etc., and a control output to the An output unit for output from an actuator, etc., a communication unit for connection to a communication network, and the like. A PLC system is constructed by, for example, mounting each unit on a base plate ha...
