Abstract: An analysis device according to one aspect of the present invention supplies a definition for a dependency relation between an input parameter and an output parameter of a standard function, which cannot be derived in a dependency analysis of a control program, the definition being supplied by use of function structure information which is external information. In other words, an analysis device according to this configuration identifies a dependency relation between an input parameter and an output parameter of the standard function on the basis of function structure information that defines a dependency relation between the input parameter and the output parameter of the standard function. Therefore, the dependency relation between the input and the output of a standard function becomes clear, so the dependency relations between a plurality of device variables that mediate the standard function can be identified.

Abstract: When user configuration data recorded in a recording medium is written into a PLC, the PLC determines, in accordance with a combination table stored in the recording medium, if a combination of the user configuration data and firmware already stored in the PLC is suitable. In addition, when firmware recorded in the recording medium is written into the PLC, the PLC determines, in accordance with the combination table stored in the recording medium, if a combination of the firmware and user configuration data already stored in the PLC is suitable.
