PROGRAMMABLE DISPLAY

摘要

A programmable display includes a display, a volatile memory, a nonvolatile memory that stores control screen data containing screen data, and a controller that loads the control screen data from the nonvolatile memory into the volatile memory at startup and displays a screen on the display on the basis of control screen data loaded into the volatile memory. The controller has a function to store the control screen data received from a screen data creation device in the nonvolatile memory and a function to store the control screen data received from the screen data creation device directly in the volatile memory.

主权项

1. A programmable display comprising:
a display; a volatile memory; a nonvolatile memory to store control screen data containing a plurality of pieces of screen data; and a controller to load the control screen data from the nonvolatile memory into the volatile memory at startup and selectively display a screen corresponding to any one of the plurality of pieces of screen data on the display on a basis of the control screen data loaded into the volatile memory, wherein in a case in which control screen data received from a screen data creation device is not for debugging, the controller stores the received control screen data in the nonvolatile memory, and in a case in which control screen data received from a screen data creation device is for debugging, the controller loads a plurality of pieces of screen data contained in the received control screen data into the volatile memory and stores the received control screen data directly in the volatile memory.
