PROBLEM TO BE SOLVED: To perform the supervision of an execution state of each program and the confirmation of an operation timing in real time and to facilitate program production, editing, etc., by displaying a ladder program and a motion program on the same screen of a programming device. SOLUTION: A dedicated instruction which simultaneously shows a ladder program and a motion program is sent to a CPU module 2 by performing key inputting of a multi-display instruction key that is previously prepared on the side of a system. The module 2 receiving it adds necessary information to the execution state display of the ladder program, a motion module 3 inputs necessary information to the execution state display of the motion program, and it is sent as one-dimensional data to a programming device 1. After the device 1 converts the one-dimensional data into bitmap data, it is simultaneously shown on a monitor. |
