    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.
