PROBLEM TO BE SOLVED: To easily perform service and maintenance management of a facility.SOLUTION: A processing section of a basic unit of a programmable controller specially permits execution of an input/output control program in the case where board formation setting data is not written into a second memory area of a storage section. The processing section specially permits execution of an input/output control program on the basis of one of the situations among a compatible input/output number range in which input/output numbers of the board formation setting data and board formation current status data coincide with each other, and an unset input/output number range and an unused input/output number range present in one and not present in the other. The processing section permits execution of an input/output control program in the case of being specially permitted even if the board formation setting data and the board formation current status data do not coincide with each other.SELECTED DRAWING: Figure 1 |
