Claims

[Scope of claim for utility model registration] From an input section composed of a plurality of input modules, two
A programmable controller that receives a signal indicating a value state as input information and executes a sequence program while referring to this input information, comprising: a first memory section that stores the sequence program and information related to processing of the sequence program; , comprising a logic decoding unit that decodes and operates a sequence program, and an input control unit that operates independently of the logic decoding unit and has a second memory that stores human input information from the input unit, and the input control unit operates independently of the logic decoding unit. After the decoding unit once sets the addresses of multiple input modules that need to be read from the input unit to the second memory unit, the address of the input module is set in the second memory unit by the input control unit. A programmable controller characterized in that an operation of reading input data from an input unit to a second memory unit based on the above and an operation of preprocessing a sequence program by the logic decoding unit are executed in parallel.
