Function unit, analog input unit, and programmable controller system

Abstract

A functional unit includes: a parameter reception unit that classifies a parameter as a first parameter or as a second parameter; a first-parameter analysis unit that analyzes the classified first parameter; a second-parameter analysis unit that analyzes the classified second parameter; a first-parameter storage unit that stores therein the first parameter analyzed by the first-parameter analysis unit; a second-parameter storage unit that stores therein the second parameter analyzed by the second-parameter analysis unit; a first processing unit that controls the first function in accordance with the first parameter stored in the first-parameter storage unit; and a second processing unit that controls the second function in accordance with the second parameter stored in the second-parameter storage unit, wherein the functional unit is controlled by a plurality of controllers.
