Learn about error and informational logging (UFL)

Errors and informational messages are sent to standard output and logged to the local PI message log or the interface specific log if the OUTPUT keyword has been set in the .ini file.

Note: The interface logs a maximum of ten identical (consequent) messages if the same error occurs more than ten times.

If an error includes an error number, you can display more details by issuing the command: "%PIHOME%\adm\pidiag" -e error_number.

For more information about interface logging, refer to the AVEVA Knowledge Base article KB00401 - How to read new UniInt 4.5.0.x and later Interface message logs.

Note: When the laboratory mode is activated (by setting the LB or LBS start-up parameters) some run-time errors cannot be recorded with the correct line number (where the error originated). This is because the LB or LBS parameters activate the internal caching and at the time of the run-time error the relation to the respective line number is already lost.
