Summary:When executing sequential processing such as a ladder logic, converting a program formed of an instruction set of another processor to a program executable by an own processor in software and then conducting processing lowers the real time property. In a control system, a storage unit stores a program for the own processor and a program for another processor. A processor reads data from the storage unit, executes processing described as a program, and gives an instruction to change over a method for acquiring data from the storage unit, to a conversion instruction unit according to data contents. A changeover unit is connected to the storage unit directly or via the conversion unit to change over the data acquiring method according to an instruction from the conversion instruction unit. The conversion unit converts data read from the storage unit to data executable by the processor, according to a conversion scheme.
