Programmable logic controller, moving image management device, moving image management system, and method for managing moving image

Abstract

A programmable logic controller or PLC () includes a clock element (), a log recorder () that records a log together with a record time into a storage device () based on a clock signal output from the clock element, an image data acquirer () that acquires moving image data indicating a moving image captured by an imaging device from the imaging device, a frame rate measurer () that measures a frame rate of the moving image indicated by the moving image data based on the clock signal output from the clock element (), a corrector () that corrects a time to be affixed to the moving image indicated by the moving image data based on the frame rate, and an image storage () that stores, into the storage device (), new moving image (DM) data indicating a moving image affixed with the time corrected by the corrector ().
