4. In the Output Error Latch Time field, 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 more reliable diagnostics. 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 is based on the RPI, the safety task
watchdog, and other application-specific variables.
