Embodiment Construction

[0037] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0038] In this embodiment, a description will be given of a control program maintenance device that registers a product structure tree in advance at the time of the first control program creation, and compares a control program in an executable format with a control program of a comparison target. comparison and comparison, and the change, addition, and deletion of inconsistencies can be easily confirmed visually. The above-mentioned product structure tree is program information for specifying the first control program and the second control program based on the configuration of the control device. The above-mentioned first The control program is stored in the control program maintenance device and becomes a comparison source control program, and the above-mentioned second control program is downloaded from the control program maintenance device and stored in a control d...

Abstract

A control program maintenance device according to an embodiment is equipped with a storage unit, a comparison unit, and a display processing unit. The storage unit stores a first program, which is a generated control program, and a product tree, which is program configuration information that associates the configurations of modules for each control device with the configurations of programs for each module so as to be expanded to the program step level. The comparison unit references the product tree and compares a newest first control program, which is registered as the comparison source, and second control programs, which are control programs uploaded from multiple control devices and used as the comparison destination. As a result of the comparison, the display processing unit displays on a display unit a match or a mismatch between the first control program and the second control programs and, when there is a mismatch, the display processing unit references the product tree, expands the configuration to the lowest level, and displays on the display unit the different locations in the control programs, within a comparison range.

Description

technical field [0001] Embodiments of the present invention relate to a control program maintenance device, a control program maintenance method, and a program. Background technique [0002] Generally, the creation of a control program for controlling a factory is designed based on the factory's required specifications, and the control program is installed in a control device equipped with a plurality of programmable controllers equipped with the control program to confirm that it operates safely. Use the requested function. [0003] However, this control program generates various modification requests such as changes, additions, and deletions based on subsequent changes in the operating conditions of the factory. [0004] For such a modification request of the running control program, the provider of the control program needs to check whether there is no mismatch between the control program managed by the host as the source of supply and the running control program before ...
