(h) Checking forced ON/OFF registration and/or cancellation status
The forced ON/OFF registration and/or cancellation (including no-setting) status
can be checked using GX Developer.
The MODE LED can be used for checking the status if at lease one device is
registered. (The MODE LED flashes.)
Note18Note19
The Universal model QCPU can also use the special register (SD840) for
checking the status.
POINT
1. The MODE LED also flashes in green when the Executional conditioned
device test function is used. To check the registration status using the MODE
LED, check the status of the Executional conditioned device test function as
well. (
2. When using SD840 to check the registration and cancel status of forced ON/
OFF, remind that SD840 is used to check the status for the Executional
conditioned device test function as well.
(i) Forced ON/OFF registration from multiple GX Developer
Forced ON/OFF of external I/O can be registered to the same CPU module from
multiple GX Developer connected via network.
When forced ON/OFF registration is performed to the same CPU module from
multiple GX Developer, note that the latest forced ON/OFF status will be
registered in the CPU module.
For this reason, the forced ON/OFF status which is different from the status
actually registered in the CPU module may be displayed on the screen of GX
Developer that executed the Forced ON/OFF function first.
When the Forced ON/OFF function is executed from multiple GX Developer, click
the
button to update the registered data and then execute the
function.

Redundant
The Basic model QCPU does not support the forced ON/OFF registration operation from the
Forced input output registration/cancellation screen (
The Basic model QCPU can forcibly turns ON/OFF external I/O only by executing a device test in
GX Developer.

In the redundant system, the MODE LED of Redundant CPUs in both system flashes.
