PROBLEM TO BE SOLVED: To solve problems in "a data transfer method and a starting method" between integrated software and an application of a programmable controller, wherein in accessing the integrated software created by a user by means of a general purpose PC as an application of the programmable controller, the integrated software accessed from a plurality of positions such as sub-routines cannot be described, and since the application of the programmable controller and the integrated software are asynchronously operated, the timing of processing, start and completion of the integrated software cannot be grasped from the application of the programmable controller. SOLUTION: A system FB table capable of uniquely accessing a system FB is provided in the programmable controller, and not only a conventional system FB but also a user FB can be registered in the table.
