Abstract: A PC, which is an information processing device, simulates a control program and displays the result of the simulation on a monitor. The PC acquires a value, and identification information identifying a variable for at least one variable at an arbitrary time during the simulation. The PC modifies the control program in accordance with an instruction from a user. The PC simulates the modified control program with the value of the variable identified by the acquired identification information as the value of the acquired variable. The PC displays the result of simulating the modified control program on the monitor.

Abstract: A controller support program causes an arithmetic unit to execute total execution time acquisition processing of acquiring a total execution time and output processing of outputting the total execution time. The total execution time is an elapsed time until execution of a control program is ended in an execution cycle since the execution cycle is started when a controller executes the control program according to an execution priority and the execution cycle, and the total execution time is also a time measured in the controller or a time estimated in a controller support device.

Abstract: In a Programmable Logic Controller (PLC) simulation system, at least one of a PLC simulator and an external simulator executes processing while checking the status of program execution in the other. For example, the PLC simulator provides a socket interface, and operates upon receiving various commands from the external simulator. The external simulator checks, using a command, whether processing for a program is being executed or the execution is finished in the PLC simulator. The external simulator checks the status of operation of the program in the PLC simulator, and executes processing accompanying writing to a PLC memory or the like, in a case where contention of access to the PLC memory does not occur.

Abstract: A controller support program causes a processor to acquire a first control execution time which is an execution time of a first control program which is an object program generated from a control source program, which is a source program of a control program generated in accordance with an object of control of a user, and operating at the simulator, the first control execution time being measured at the simulator.

Data representing the estimated execution time is output.
