(f) Number of registerable devices
Forced on/off can be registered for 32 devices in total.
(g) When output Y contact is used in a sequence program
On/off operations in a sequence program are given priority.
(h) Checking forced on/off registration status
Forced on/off execution status can be checked by:
• reading the forced on/off registration status by GX Developer,
• flashing of the MODE LED (green), (The MODE LED flashes in green when at least one forced on/off is
registered.) or
• the on status of the 1st bit in SD840 (Debug function usage).
●
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. (
●
When using SD840 to check the registration or cancellation status, remind that SD840 is used to check the status of
the executional conditioned device test function as well.
(i) Forcibly turning input or output on/off from multiple GX Developers
Forced on/off can be registered to a single CPU module from multiple GX Developers connected via network.
In this case, the last registration will be effective.
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 registered forced on/off earlier.
When the forced on/off registration is performed from multiple GX Developers, click the "Update status" button
to update the registered data and execute the function.
