Configure the Module in a GuardLogix Controller
4.
From the Output Error Latch Time box, enter the time the module holds
an error to make sure the controller can detect it (0…65,530 ms, in
increments of 10 ms - default 1000 ms).
This provides you more reliable diagnostics and enhances the changes that
a nuisance error is detected.
The purpose for latching output errors is to make sure that intermittent
faults that may exist only for a few milliseconds are latched long enough to
be read by the controller. The amount of time to latch the errors will be
based on the RPI, the safety task watchdog, and other application-specific
variables.

Saving and Downloading
Module Configuration
We recommend that after a module is configured you save your work.
If after downloading the program the MS and NS status indicators on the
POINT Guard I/O module are not both solid green, this may be due to loss of
ownership. The ownership is based on the following:
•
POINT Guard I/O module number
•
POINT Guard I/O safety network number
•
GuardLogix slot number
•
GuardLogix safety network number
•
Path from GuardLogix controller to POINT Guard I/O module
•
Configuration signature
If any of these change, the connection between the GuardLogix controller and
the POINT Guard I/O module is lost, and a yellow yield icon in the
RSLogix 5000 tree appears. For more information, see
