Control device and method of controlling the same

A control device, comprising at least a programmable circuit unit and an arithmetic processing unit connected to the programmable circuit unit, capable of executing a user program in the arithmetic processing unit,

• wherein the programmable circuit unit comprises:
• a storage unit, storing configuration data of a functional unit configured in the programmable circuit unit;
• and
• an error detection unit, detecting a soft error of the storage unit,
• the arithmetic processing unit comprises:
• a memory unit, storing map information including position information in the programmable circuit unit corresponding to the functional unit in the programmable circuit unit;
• and
• an abnormality determination unit, determining a correspondence between a position of the soft error detected by the error detection unit and the functional unit on the basis of the map information, and
• the arithmetic processing unit comprises:
• continuing an operation of the control device when the abnormality determination unit determines that the position of the soft error corresponds to an unused portion of the functional unit, and
• executing a predetermined process when the abnormality determination unit determines that the position of the soft error corresponds to a used portion of the functional unit.
