PROGRAMMABLE DISPLAY SYSTEM, SAID PROGRAMMABLE DISPLAY AND METHOD FOR PROXY PRESENTATION ON SCREEN

摘要

PROBLEM TO BE SOLVED: To continue operation even in the event of an LCD failure of a programmable display.;SOLUTION: When an LCD failure is detected by an LCD failure detection unit 14, a communication-at-LCD-failure unit 13 communicates with other programmable displays 10 and transmits display data of a monitoring/operation screen when a programmable display for proxy presentation is determined. As a result, on the side of the programmable display 10 for proxy presentation, a communication-at-other-display-failure unit 21 receives the display data and have a display control unit 23 display not only a monitoring/operation screen of own apparatus but also a monitoring/operation screen of the programmable display 10 with the LCD failure.;COPYRIGHT: (C)2014,JPO&INPIT
