12 Troubleshooting

The unit has many self-diagnostic options. It monitors itself automatically during operation.

Warnings and error states are displayed even if the display is switched off. Error indications are also
available via IO-Link.

The status signals are classified according to NAMUR recommendation NE107.

If several diagnostic events occur simultaneously, only the diagnostic message of the event with the
highest priority is displayed.

If a process value fails, the other process values are still available. Exception: If the process value for
flow fails, no other process values are output.

Additional diagnostic functions are available via IO-Link
