POINT
(1) Always cancel the registration of the forced input/output after the device test
has been completed.
The REM.LEDs on the remote I/O module for "in device testing" will flash.
Once the device testing has been completed, it is possible to check that the
REM.LEDs have stopped flashing.
If the device test is not cancelled, the remote I/O network could malfunction.
(2) After the device has been cancelled, the module operates with data remaining
from the device test.
• When the Y output is on with GX Developer and the device test is cancelled,
operation is performed in the Y output on status.
• When the X input is on with GX Developer and the device test is cancelled,
operation is performed in the X input on status.
