Chapter 7 Configure and Replace Safety Modules
The SNN is a time-based number that uniquely identifies subnets across all
networks in the safety system. All Compact 5000 I/O safety modules in a same
system use the same SNN by default.
• Local Compact 5000 I/O safety modules are automatically assigned the
same SNN as the 5069 Backplane SSN in the controller configuration.
• Remote Compact 5000 I/O safety modules are automatically assigned
the same SNN.
The Logix Designer application assigns an SNN to the first safety
module that is added to a remote system. The application assigns the
same SNN to additional safety modules that are added to this remote
I/O system.
For more information on Safety Network Numbers, see the GuardLogix 5580
and Compact GuardLogix 5380 Controller Systems Safety Reference Manual,
