Abstract
A programmable controller having self-diagnosis unit 60 (70) for self-diagnosis, wherein the self-diagnosis unit 60 (70) comprises data storage unit 61 (71) for storing data pertaining to an inspection unit for which the inspection is completed, and inspection start unit 62 (72) for starting the inspection from the next inspection unit of the inspection unit for which the inspection is already completed at the time before the power is turned on, when performing a self-diagnosis that occurs after the power is turned on, based on the data stored in the data storage unit 61 (71).
Claims12
A programmable controller comprising:
- a storage device that has a plurality of memory areas being allocated with individual addresses;
- and a self-diagnosis unit that performs self-diagnosing whether or not the storage device is normal by sequentially inspecting the plurality of memory areas by inspection units of a plurality of inspection units, said plurality of inspection units being within said plurality of memory areas,
- wherein the self-diagnosis unit includes:
- a data storage unit that stores data pertaining to an inspection unit for which inspection is completed;
- and
- an inspection start unit that starts the inspection from a next inspection unit relative to the inspection unit for which the inspection is already completed at a time before a power is turned on, when performing a self-diagnosis after the power is turned on, based on the data stored in the data storage unit.
