Development support device, development support method, and non-transitory computer readable medium

A development support device supporting development of a control program for a controller, the development support device comprising:

• a storage device that stores a correspondence relationship between a data type usable in a non-periodic-execution programming language and a data type usable in a periodic-execution programming language,
• wherein the storage device further stores definition information including a data type of an argument for a non-periodic-execution function module defined by the non-periodic-execution programming language and a data type of a return value for the non-periodic-execution function module,
• wherein the development support device further comprises a control device generating a periodic-execution function module for invoking the non-periodic-execution function module and is usable in the control program, and
• wherein the control device
• specifies a data type that is in the periodic-execution programming language and corresponds to the data type of the argument based on the correspondence relationship and the definition information, and establishes an input variable for reflecting a value of the argument as an input interface of the periodic-execution function module, the input variable being an input variable of the data type, and
• specifies a data type that is in the periodic-execution programming language and corresponds to the data type of the return value based on the correspondence relationship and the definition information, and establishes an output variable for reflecting the return value as an output interface of the periodic-execution function module, the output variable being an output variable of the data type.

A development support method of supporting development of a control program for a controller, the development support method comprising:

• a step of causing a development support device to acquire a correspondence relationship between a data type usable in a non-periodic-execution programming language and a data type usable in a periodic-execution programming language;
• a step of causing the development support device to acquire definition information including a data type of an argument for a non-periodic-execution function module defined by the non-periodic-execution programming language and a data type of a return value for the non-periodic-execution function module;
• and
• a generating step of causing the development support device to generate a periodic-execution function module for invoking the non-periodic-execution function module and is usable in the control program,
• wherein the generating step includes
• a step of causing the development support device to specify a data type that is in the periodic-execution programming language and corresponds to the data type of the argument based on the correspondence relationship and the definition information, and to establish an input variable for reflecting a value of the argument as an input interface of the periodic-execution function module, the input variable being an input variable of the data type, and
• a step of causing the development support device to specify a data type that is in the periodic-execution programming language and corresponds to the data type of the return value based on the correspondence relationship and the definition information, and to establish an output variable for reflecting the return value as an output interface of the periodic-execution function module, the output variable being an output variable of the data type.
