Abstract
The present invention provides a technology for invoking a non-periodic-execution function module from a periodic-execution control program. A control system that comprises first and second control parts (C1, C2) and a storage device that stores control programs (210, 211) for a controller. The control programs (210, 211) include a periodic-execution function module (55B) that invokes a non-periodic-execution function module (55A). The first control part (C1) reflects the value of an input variable for the periodic-execution function module (55B) in an argument for the non-periodic-execution function module (55A) and outputs an execution start command for the function modules to the second control part (C2). The second control part (C2) outputs a return value for the non-periodic-execution function module (55A) to the first control part (C1). The first control part (C1) reflects the return value in an output variable for the periodic-execution function module (55B).
