<P>PROBLEM TO BE SOLVED: To quickly alternate a ladder program for simulation and a ladder program for normal operation with each other. <P>SOLUTION: A ladder program 111 for normal operation and a ladder program 112 for simulation are executed, and a main memory 100 has a data register 121 for normal operation and a data register 122 for simulation. When the ladder program 111 for normal operation is selected through an input part 203, the ladder program 111 for normal operation controls a device 2 to be controlled using the data register 121 for normal operation, and when the ladder program 112 for simulation is selected through the input part 203, the ladder program 112 for simulation performs simulation using the data register 121 for normal operation and the data register 122 for simulation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
