USE TOUCH PANEL AFTER BACKLIGHT BURNOUT
This option designates whether touch-operation is disabled or not when the back-
light burns out. If this selection is set to [OFF], touch-operation will be disabled
when the backlight burns out, which prevents the GP from sending input signals to
the PLC.
• When the backlight burns out, the Status LED's orange light turns ON, and the
System Data Area's "Status" bit 10
*1
will turn ON.
• The GP-2401/2501/2601 series models use two backlights (CCFL). The GP detects
backlight burnout when one of the two backlights burns out, and disables touch-
operations.
• If the [SYSTEM RESET] option is set to [ON], only "System Reset" can still be
performed by touch-operation in case of backlight burnout.
• If the backlight burns out when the GP is OFFLINE, touch-panel operation is
enabled, regardless of these settings.
SETUP LCD (GP-2501L only)
To reverse the screen display colors, touch the SET UP TOUCH PANEL screen'
[SET UP LCD] to change the setting from "NORMAL" to "REVERSE", and then
touch the "SET" key. The display color will be reversed and the previous screen
will reappear.
Normally, the GP unit detects a backlight burnout by monitoring the
backlight's current flow, however, the GP may fail to detect this condi-
tion, depending on the type of backlight problem.
*1 Bit +6 (when using the Direct Access method), and bit +11 (when using the Memory
Link method), will turn ON.
