PRELIMINARY Product Safety Advisory 2017-06-002 – RSLogix 5000 / Studio 5000 V24 through V30 Safety Configuration Signature when using Generic EtherNet/IP Safety Module Profile (201706002)


This PRELIMINARY Product Safety Advisory informs you of an anomaly that exists with RSLogix 5000 and Studio 5000 Logix Designer V24 through V30.  This anomaly only affects 1756 GuardLogix projects, developed using a version prior to V24 that have been upgraded to version V24 through V30 and use the Generic EtherNet/IP Safety Module profile.  This profile is typically used for CIP Safety devices such as robots.  If your GuardLogix project does not use this profile you are not affected and no action is required on your part.


The Generic EtherNet/IP Safety Module profile does not properly handle an online change made to the Safety Configuration Signature ID on the Safety page of the profile.  The changed Safety Configuration Signature ID does not result in the Safety connection closing.  This causes the configuration in the GuardLogix controller to be different than the configuration of the CIP Safety device, resulting in potential unexpected operation.


Rockwell Automation is currently investigating this anomaly and will provide updated information in the near future.  Customers who may be affected by this anomaly are advised to delete the CIP Safety devices using the Generic EtherNet/IP Safety Module profile in their GuardLogix project and recreate them.  This will result in future online changes to the Safety Configuration Signature ID to cause the Safety connection to close.


If you have any questions or concerns please contact your System Integrator or Rockwell Automation Technical Support.  The Knowledgebase article will be updated when additional information is available at
