Safety Outputs
Section 5-4
Error Latch Time Setting
The time to latch the error state when an error occurs in a safety output circuit
can be set. The error state will continue until the error latch time passes even
if the cause of the error is momentarily removed. When monitoring errors from
a monitoring system, take the monitoring interval into account when setting
the error latch time.
The error latch time can be set in increments of 10 ms between 0 and 65,530
ms. The default is 1,000 ms.
Resetting Errors
All conditions below are necessary to recover from an error that has occurred
in a safety output.
• The cause of the error must be removed.
• Error latch time must have passed.
• The output signals to the output I/O tags from the user application that
correspond to the safety output terminals must go inactive.
Note
If the Dual Channel Mode is set for two outputs to implement redundant cir-
cuits and an error is detected for one of the outputs, the other output can be
made to go inactive without relying on the user program. If the redundant cir-
cuits are implemented using two outputs in Single Channel Mode, the user
program must be used to detect the error (using the External Device Monitor-
ing function block).
