, noting that in most cases, you use the
default provided by the Logix Designer application.
The purpose of the safety network number (SNN) is to make sure that
every module in a system can be uniquely identified. We suggest that all
safety modules on a network have the same SNN, to make
documentation easier. During configuration, the Logix Designer
application defaults a safety device’s SNN to match the SNN of the
lowest safety node on each network.
