Engineering apparatus, control method of engineering apparatus, and program for generating executable code for controlling target hardware

A control method of an engineering apparatus for generating executable code from a control application, created in a first programming language, for controlling target hardware, the executable code causing the target hardware to operate, the control method comprising:

• converting control logic included in the control application into control logic code expressed in a second programming language;
• expressing a type definition code in the second programming language and outputting the type definition code, the type definition code corresponding to a data block structure of data held by a function block included in the control application;
• expressing a memory allocation code in the second programming language and outputting the memory allocation code, the memory allocation code allocating an instance of the function block included in the control application to memory in the target hardware;
• and
• using at least one of a compiler or a linker for the target hardware to generate the executable code based on the control logic code, the type definition code, and the memory allocation code,
• wherein when generating the executable code, the control method further comprises using the compiler/linker to link a communication service program, a control service program, and a library that are precompiled for the target hardware,
• wherein the communication service program is configured to transmit and receive information to and from the engineering apparatus when the executable code is executed on the target hardware,
• wherein the control service program is configured to schedule execution of the executable code when the executable code is executed on the target hardware,
• wherein the control method further comprises transmitting an ID of an instance of the function block to which data to be debugged belongs and an offset position from top address of the instance of the function block to the communication service program, and
• wherein the communication service program is configured to refer to data within the instance of the function block corresponding to the received ID of the instance of the function block.

A non-transitory computer-readable storage medium with an executable program stored thereon, wherein the program controls an engineering apparatus for generating executable code from a control application, created in a first programming language, for controlling target hardware, the executable code causing the target hardware to operate, the program causing the engineering apparatus to:

• convert control logic included in the control application into control logic code expressed in a second programming language;
• express a type definition code in the second programming language and output the type definition code, the type definition code corresponding to a data block structure of data held by a function block included in the control application;
• express a memory allocation code in the second programming language and output the memory allocation code, the memory allocation code allocating an instance of the function block included in the control application to memory in the target hardware;
• and
• use at least one of a compiler or a linker for the target hardware to generate the executable code based on the control logic code, the type definition code, and the memory allocation code,
• wherein when generating the executable code, the program causes the engineering apparatus to use the compiler/linker to link a communication service program, a control service program, and a library that are precompiled for the target hardware,
• wherein the communication service program is configured to transmit and receive information to and from the engineering apparatus when the executable code is executed on the target hardware,
• wherein the control service program is configured to schedule execution of the executable code when the executable code is executed on the target hardware,
• wherein the program causes the engineering apparatus to transmit an ID of an instance of the function block to which data to be debugged belongs and an offset position from top address of the instance of the function block to the communication service program, and
• wherein the communication service program is configured to refer to data within the instance of the function block corresponding to the received ID of the instance of the function block.
