Considerations When Replacing Guard I/O Modules

GuardLogix Controllers versus SmartGuard Controllers
There is one major difference in functionality between the GuardLogix and
SmartGuard safety controllers that affects the replacement of safety I/O
modules. GuardLogix controllers retain I/O module configuration on-board and
are able to download the configuration to the replacement module. SmartGuard
controllers do not retain I/O module configuration so you need to use
RSNetWorx for DeviceNet software to download the configuration to the
replacement module.
Replacing an I/O Module
When Using a SmartGuard
Controller
Follow these steps to replace an I/O module when using a SmartGuard controller.
1. Set the rotary switches of the replacement module to match the node
number of the original module.
2. In RSNetWorx for DeviceNet software, open your project.
