Considerations When
Replacing POINT Guard I/O
Modules
When POINT Guard I/O modules are connected to a GuardLogix or
SmartGuard controller, consider the following when replacing the modules.
The topic of replacing a safety I/O module that sits on a CIP safety network is
more complicated than standard devices because of the safety network number
(SNN). The module number and SNN make up the safety module’s identifier.
Safety devices require this more complex identifier to guarantee that duplicate
module numbers do not compromise communication between the correct safety
devices.
