Information processing device, simulation method, and program

A simulation method on an information processing device for simulating a control program executed in a controller that controls operations of a machine for each control cycle, the simulation method with steps comprising:

• simulating the control program;
• displaying the result of the simulation;
• acquiring a value for at least one variable and acquiring identification information identifying said variable at an arbitrary time during the simulation;
• modifying the control program;
• simulating the modified control program while using the value of the variable identified by the acquired identification information as the value of the acquired variable;
• and
• displaying the result of simulating the modified control program.

A program for controlling an information processing device that simulates a control program executed in a controller controlling operations of a machine for each control cycle, the program with steps comprising:

• simulating the control program;
• displaying the result of the simulation;
• acquiring a value for at least one variable and acquiring identification information identifying said variable at an arbitrary time during the simulation;
• modifying the control program;
• simulating the modified control program while using the value of the variable identified by the acquired identification information as the value of the acquired variable;
• and
• displaying the result of simulating the modified control program, the above steps executed on a processor in the information processing device.
