USE TOUCH PANEL AFTER BACKLIGHT BURNOUT
This option allows the user to enable [ON] or disable [OFF] the touch operation
when the backlight burns out. Setting this item to [OFF] prevents the GLC from
sending input signals to the PLC.
When the Backlight Burns Out:
•
The Status LED’s orange light will turn ON.
•
The System Data Area’s Status bit 10
*
1
will turn ON.
•
If the SYSTEM RESET item is set to ON, only SYSTEM
RESET can still be performed by touch operation.
•
If the GLC is in OFFLINE mode, the touch-panel operation
will become enabled, regardless of the settings.
Normally, the unit detects backlight burnout by monitoring the current.
However, depending on the problem with the backlight, the unit may fail
to detect this condition.
