Support device, method, and recording medium for simplifying control program changing operation

A method executed in a support device for supporting development of a control program executed in a control device that controls a control target, the method comprising the steps of:

• computing identification information in accordance with details of each unit program with respect to each unit program constituting a first program;
• transferring a unit program and identification information associated with the unit program to the control device;
• generating a changed unit program in accordance with a change operation on any one unit program constituting the first program;
• transferring the changed unit program to the control device in operation on condition that the same identification information as identification information associated with a unit program constituting the control program is present in the control device;
• generating a changed variable table in accordance with a change operation on a variable table referring to the control program;
• transferring the changed variable table to the control device, wherein the variable table includes a plurality of variables that are referred to from the control program, and all values the plurality of variables of the variable table before the change operation are included in the changed variable table;
• transferring a variable table of a transfer target and one or more unit programs in a predetermined order or a designated order;
• and
• determining the transfer order of the variable table of the transfer target and the one or more unit programs in accordance with a characteristic value of the control device of a transfer destination.

A non-transitory recording medium storing a support program for implementing a support device for supporting development of a control program to be executed in a control device that controls a control target, the support program causing a computer to:

• compute identification information in accordance with details of each unit program with respect to each unit program constituting a first program;
• transfer a unit program and identification information associated with the unit program to the control device;
• generate a changed unit program in accordance with a change operation on any one unit program constituting the first program;
• and
• transfer the changed unit program to the control device in operation on condition that the same identification information as identification information associated with a unit program constituting the control program is present in the control device,
• wherein the support program causing the computer to generate a changed variable table in accordance with a change operation on a variable table referring to the control program, and transfer the changed variable table to the control device, wherein the variable table includes a plurality of variables that are referred to from the control program, and all values the plurality of variables of the variable table before the change operation are included in the changed variable table,
• the support program causing the computer to transfer a variable table of a transfer target and one or more unit programs in a predetermined order or a designated order, and
• the support program causing the computer to determine the transfer order of the variable table of the transfer target and the one or more unit programs in accordance with a characteristic value of the control device of a transfer destination.
