1. 1

   Verify the user's login credentials and associated security privileges within the Rockwell Automation software (e.g., Studio 5000 Logix Designer) on the engineering workstation.

2. 2

   Check the PLC controller's security settings and user access control configuration (e.g., in Controller Properties) to ensure the attempted operation is permitted.

3. 3

   Inspect the network configuration and connectivity between the engineering workstation and the PLC to rule out communication issues affecting authentication.
