シーケンスコントローラ。[Claims for Utility Model Registration] 1. In a sequence controller that decodes and executes a user program indicating the operational relationship between input and output, an instruction is provided to specify an operation mode of the sequence controller itself according to an operation factor, and the instruction and a detection means for detecting an operation factor that is a target of this operation mode, the instruction is stored as a user program separate from the user program indicating the operational relationship of the input and output, and the When an operating factor is detected by the detection means, the instruction means decodes and executes an instruction corresponding to the detected operating factor,
A sequence controller characterized in that the sequence controller itself is controlled in an operation mode specified by the instruction. 2. Utility Model Registration In the sequence controller according to claim 1, the command includes a selection/declaration command for selecting/declaring an operation mode, and selection information indicating what kind of selection is to be made,
If the selection/declaration command is not present, a preset operation mode is executed, and if the selection/declaration command is present, the process of the operation mode specified by the selection information is executed. Sequence controller.
