Click steps to track your progress.

Verify if any other programming workstation (e.g., Studio 5000 Logix Designer) is currently online with the Logix 5000 controller.
- 2
Inspect RSLinx Classic or FactoryTalk Linx communication drivers for active or orphaned connections to the controller.
- 3
Check if any HMI, SCADA, or custom application has established an exclusive lock on the controller program or specific tags.

Attempt to go offline from the current programming session and then reconnect to clear any potentially hung communication sessions.
- 5
Coordinate with other personnel to ensure no other users or applications are attempting simultaneous access to the controller resources.
