Abstract: Techniques for converting an initial control program code version to a new control program code version are disclosed herein. In at least one implementation, input and output states of an industrial controller are monitored while the industrial controller executes the initial control program code version to operate a machine system and functional design specification for the industrial controller is generated. An instruction set of the industrial controller is converted into a new instruction set for a new industrial controller, and one or more equivalent instructions in the new instruction set that are equivalent to instructions in the instruction set of the industrial controller are identified. The new control program code version is generated based on at least the functional design specification and the one or more equivalent instructions in the new instruction set that are equivalent to the instructions in the instruction set of the industrial controller.

Abstract: Techniques to facilitate generation of controller application code that emulates functionality of an industrial controller are disclosed herein. In at least one implementation, a computing system interfaces with the industrial controller and monitors input and output states of the industrial controller while the industrial controller operates a machine system. The input and output states of the industrial controller used to operate the machine system are analyzed to generate a functional design specification for the industrial controller. The controller application code that emulates the functionality of the industrial controller is generated based on the functional design specification.
