Error Message
Cause and Solution
RGAA001 Watchdog error
The possible causes are that the operation has entered
an endless loop in the program, or that the program
uses many instructions which wait for logic pro-
grams. With GP-Pro EX, select [Main Unit Settings]
in [System Settings Window], open the [Logic Set-
tings] tab, and set the time for [WDT (Watchdog
Timer) Settings] longer.
