A. From the Safety dialog, click Advanced to see the Advanced
Connection Reaction Time Limit Configuration dialog.
Make sure that input modules are set to match the need. The
smallest input RPI allowed is 6 ms. Selecting small RPI's
consumes network bandwidth and may cause nuisance trips
because other devices can't get access to the network.
As an example, a safety input module with only ESTOP switches
connected to it generally may work well with settings of
50...100 ms. An input module with a light curtain guarding a
hazard may need the fastest response that is possible.
Selecting appropriate RPI's will result in a system with maximum
(best) performance.
You should always analyze each safety channel to determine what is

appropriate. These examples are simply to convey concepts and
should not be used as any kind of official recommendation.
We recommend that you keep
the Timeout Multiplier and
Network Delay Multiplier at
their default values of 2
and 200.
