Safety Drive in a GuardLogix
System
If you are relying on a portion of the integrated safety system to maintain SIL 3
behavior during drive replacement and functional testing, do not use the
Configure Always feature.
Use the Configure Always feature when you are not relying on the entire routable

-ERS2 servo drive is replaced and the DeviceID of the new
drive matches the original, you can download the configuration from the safety
controller. The DeviceID is a combination of the node/IP address and the safety
network number (SNN), and is updated whenever the SNN is set.
If the project is configured as Configure Only When No Safety Signature Exists,
