b. From the Module Number pull-down menu, choose a unique module
number that corresponds to the module’s position in the chassis.
c. In the Description field, type a description, if desired.
d. In the Safety Network Number field, use the default setting.
For a detailed explanation of the safety network number (SNN), see the
GuardLogix Controller Systems Safety Reference Manuals listed in the
Additional Resources on
page 13 , 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.
