What to establish before troubleshooting
Define the complete data path before changing anything: client, tag, shortcut, controller, FactoryTalk Directory scope, data server, and the workstation or server that owns the connection.
A path that works from an engineering laptop does not prove the runtime path. Validate from the HMI server, data server, or Gateway host where the failure actually occurs.
Capture FactoryTalk Diagnostics, shortcut targets, driver configuration, service state, and recent application or controller changes before restarting services.
Abbreviated worked example
Example: development tags work but runtime shows bad quality
A FactoryTalk View project browses the controller from an engineering workstation, while the runtime client displays question marks or stale values.
- 1Identify whether the runtime uses a Local or Network FactoryTalk Directory and which server owns the data path.
- 2Compare the runtime shortcut target, controller identity, IP address, and slot with the path used in development.
- 3Review diagnostics on the runtime host before restarting Linx or editing the shortcut.
Result: The comparison shows whether the failure is in the runtime directory or shortcut path rather than in the controller tag itself.
Caution: Back up the application and communication configuration before reassigning shortcuts or restarting production services.
