Replacing an Integrated
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
integrated safety control system to maintain PLe/SIL 3 behavior during the
replacement and functional testing of a 2198-H
xxx-ERS2 servo drive. Drive
replacement is configured on the Safety tab of the GuardLogix controller.
Figure 74 - Setting the SNN with a GuardLogix Controller
Replacement with Configure Only When No Safety Signature Exists
Enabled
When a 2198-H
xxx-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,
follow the appropriate instructions in
Table 80 to replace a 2198-H
xxx-ERS2
drive based on your scenario. Once you have completed the steps correctly and
the DeviceID matches the original, the safety controller is enabled to download
the proper drive configuration and re-establish the safety connection.
