Configure and Replace Safety Modules Chapter 7
General Category
The General category appears first when you create a module. The parameters in
this category are the same for all FLEX 5000 digital I/O modules.
You use this category to complete the following tasks:
• Name the module.
• Assign a node number.
• Describe the module.
• Access the Module Definition.
Safety Network Number
The Logix Designer application automatically assigns a Safety Network Number
(SNN) to FLEX 5000 safety I/O modules as they are added to the project.
The SNN is a time-based number that uniquely identifies subnets across all
networks in the safety system. All FLEX 5000 safety I/O modules in a same
system use the same SNN and are automatically assigned the same SNN by
default.
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,
publication 1756-RM012
