Unable to read '<tag name>' on device ' <channel name/device name>'
Error Type:
Warning
Possible Cause:
A database tag has been created within the iFIX database containing an invalid I/O address.
Solution Steps:
1. Delete the tag from the iFIX database (if not already deleted).
2. Delete the "<server project>_FIX.ini" file.
3. Export the PDB database from the iFIX Database Manager.
4. Re-import the exported file so that "<server project>_FIX.ini" is recreated with the current list of iFIX database
items. This will allow each item that is in the iFIX database to be re-validated with the server.
