Abstract
A method for modifying an industrial control program is provided, the industrial control program comprising a first program element having a safety classification and a second program element not having the safety classification. The method comprises: identifying, in program source code of the first program element, a call to the second program element, and generating a modified program source code, comprising replacing, in the program source code, the call to the second program element by an auxiliary program element, the auxiliary program element being compliant with the safety classification.
Claims18
A method for modifying an industrial control program, the industrial control program comprising a first program element having a safety classification and a second program element not having the safety classification, the method comprising:
- identifying, in program source code of the first program element, a call to the second program element;
- and
- generating a modified program source code, comprising replacing, in the program source code, the call to the second program element by an auxiliary program element, the auxiliary program element being compliant with the safety classification.
A computer program comprising computer-readable instructions stored in a non-transitory storage, wherein the computer-readable instructions are adapted, when executed on a computing device, to implement on the computing device a method for modifying an industrial control program, the industrial control program comprising a first program element having a safety classification and a second program element not having the safety classification, the method comprising:
- identifying, in program source code of the first program element, a call to the second program element;
- and
- generating a modified program source code, comprising replacing, in the program source code, the call to the second program element by an auxiliary program element, the auxiliary program element being compliant with the safety classification.
A system for modifying an industrial control program, the industrial control program comprising a first program element having a safety classification and a second program element not having the safety classification, the system comprising:
- a code analysis unit adapted to identify, in program source code of the first program element, a call to the second program element;
- and
- a code modification unit adapted to generate a modified program source code, comprising to replace, in the program source code, the call to the second program element by an auxiliary program element, the auxiliary program element being compliant with the safety classification.
