ントローラ。[Claim for Utility Model Registration] Means for detecting the cycle time of one cycle of user program execution, the number of service request interrupts made from a programmable controller to peripheral units, and the number of accesses by peripheral units in response to service request interrupts. A means of calculating the access frequency from the above cycle time and access frequency,
Fuzzy control using membership functions allows
A programmable controller comprising: inference means for calculating an interrupt interval of a service request; and means for executing interrupt processing of a service request based on the calculated interrupt interval.
