Abstract

The disclosure provides a control device and a control method capable of properly executing a termination process even in a case where a power shutdown occurs again during the execution of a restart process. A programmable logic controller includes a central processing unit module, a power shutdown detection part, a power supply holding circuit, and a power detection part. The central processing unit module executes the termination process with the power supplied from the power supply holding circuit in a case where the power shutdown detection part has detected the power shutdown, and the central processing unit module executes a reboot process on condition that the power supply holding circuit holds a power amount equal to or greater than a reference amount based on the power detection part in a case where the power shutdown detection part has detected a return of the power supply from the power shutdown.
