Abstract: To provide a PLC having a data collection function and a data display screen generation function. The PLC includes: a collection section that collects a symbol value stored in a symbol, which is a device or a variable serving as a collection target, according to the application program; a determination section that determines whether or not the symbol value collected by the collection section according to the application program satisfies a normal condition set for the application program to detect a status different from usual regarding the symbol value; and a generation section that generates a display screen including a determination result of the determination section and information indicating the symbol value collected by the collection section according to the application program.

Abstract: A programmable display includes a display data generator that generates display data for pages corresponding to their page identifier, a display portion that displays a page corresponding to the page identifier on its display screen based on the display data that is generated by the display data generator, and a touch detector that detects touch operations on the display screen of the display portion. The display portion generates display data for displaying the device wave of the device that is specified by the subject device settings based on the chronological data, which is stored in the PLC, when the touch detector detects a predetermined second touch operation on the display screen. The display portion displays a second page or a device wave on the display screen based on the display data that is generated by the display data generator.
