Using the T100MD888+ to monitor analog and digital inputs along with digital output controls. A 4x20 LCD is also in use to display menus and data.
After running without issue for 6 months, the LCD now appears to turn off on occassion. After cycling power, the LCD functions normally. The LCD backlite stays on with the power. Connections have been tested, a second LCD was tested with the same results. The problem appears to be on the PLC board and not with the LCD (the 2nd LCD unit has only a few hours of run time).
Why does the LCD appear to turn off?
Is there any method other than power off/on to reset the LCD connection?
Has this problem been noted?
Is there any solution?
The LCD data may be monitored from a computer connected via XServer and the data programmed to the screen is updating.
Thank you,
Michael
