PROBLEM TO BE SOLVED: To visualize a relation between a control algorithm defined in a control program and input/output equipment included in a control system in an easily intelligible format.SOLUTION: A device group extraction part 123 and a portable device extraction part 124 specify which input/output equipment is the target of the input/output of a signal for each variable for signal input/output described in a control program. Thus, a graph generation part 112 is able to generate display information in which nodes express variables, and oriented edges express inter-variable dependence, and a control algorithm defined in the control program is expressed with the connection of the nodes and the oriented edges, and nodes for each variable for signal input/output are expressed in association with the input/output equipment. As a result, a relation between the control algorithm defined in the control program and the input/output equipment included in the control system can be visualized in an easily intelligible format. |
