Abstract

According to the present invention, an input operation unit receives an input related to generation and editing of a ladder diagram program. A partial circuit search unit searches and extracts a partial circuit corresponding to a ladder circuit of an inputted command name when the input operation unit receives the command name of the ladder circuit to be inserted into the ladder diagram program. Adisplay unit outputs an input candidate corresponding to the partial circuit extracted by the partial circuit search unit. A replacement unit receives selection of the input candidate outputted fromthe display unit, and replaces, with the selected input candidate, the ladder circuit, the command name of which has been inputted by the input operation unit.

Description

technical field [0001] The present invention relates to a technology that supports creation and editing of a ladder diagram program executed by a programmable logic controller (Programmable Logic Controller, PLC) (programmable controller) or the like. Background technique [0002] Conventionally, a ladder program executed by a PLC (programmable logic controller) was often created by a general-purpose computer such as a personal computer, and uploaded to the PLC. In a general-purpose computer, there are programs installed (installed) to cause the general-purpose computer to execute the following functions: a creation and editing function for creating and editing a ladder program, an upload function for uploading a ladder program to a PLC, and a download function from a PLC. (download) The download function of the ladder diagram program, etc. [0003] Furthermore, as a device that supports creation of a ladder program, there is a device described in Patent Document 1, for exa...
