PROBLEM TO BE SOLVED: To provide a programmable logic controller which can immediately reflect a change of input/output in processing. SOLUTION: This programmable logic controller captures input data by an input module, performs operation by a CPU module, and outputs output data from an output module. An input notification section which notifies the CPU module that input data is stored in an input data storage is prepared in the input module, and an output notification section which notifies the output module that output data is sent to an output data storage is prepared in the CPU module.
