Abstract
In a programmable logic controller, a flag data update receiver receives an update of flag data indicating whether activation of a second execution element is permitted or prohibited. An interrupt receiver receives an interrupt instruction indicating a request for activating the second execution element independently of whether a transition condition is satisfied. An interrupt preventer maintains, when the interrupt instruction is received and latest flag data indicates that the activation of the second execution element is prohibited, an inactive state of the second execution element and outputs an interrupt invalidation error indicating that the interrupt instruction is invalidated. An executor activates the second execution element when the interrupt instruction is received and the latest flag data indicates that the activation of the second execution element is permitted.
