摘要

PROBLEM TO BE SOLVED: To quickly move the specification processing of a control program in a preferential manner regardless of an activity ratio or appearance frequency.;SOLUTION: A PLC 100 includes: a cache memory (140) incorporated in a CPU 110; a program temporary execution part 126 for referring to preload setting information in which the presence/absence of preload setting for preloading the processing components of a control program for controlling external equipment 170 in a cache memory is set for each processing component, and for, when it is determined that the preload setting of each processing component of the control program is present, executing the processing components to preload and lock the processing components in the cache memory during initialization processing; and a program execution part 130 for cyclically executing the control program while referring to the cache memory in a preferential manner after the initialization processing.;COPYRIGHT: (C)2013,JPO&INPIT
