Device description for field devices
Derating

Device name
Before an IO device can be addressed by an IO controller, it must have a device name.
An IO device is delivered without a device name. An IO device can only be addressed by the
IO controller after it has been assigned a device name via the PG/PC or via the topology, e.g.
for the transfer of configuration data (such as IP address) during startup or for the exchange of
user data during cyclic operation.
Diagnostics
Monitoring functions for the recognition, localization, classification, display and further
evaluation of errors, faults and alarms. They run automatically during plant operation. This
increases the availability of plants because commissioning times and downtimes are reduced.
Diagnostics Missing Supply Voltage
Diagnostics for missing or insufficient supply voltage L+.
Diagnostics Short-Circuit to Ground
Enable diagnostics (for one DIQ channel or all DIQ channels).
You can enable diagnostics for an activated digital output.
The diagnostics monitors the digital output and signals when a short-circuit of the digital output
to ground occurs.
A short-circuit to ground is only recognized for an output value = 1 (output is switched on).
Note on short-circuit signal
If the output is deactivated during an active short-circuit (output value = 0), the diagnostics
"Short-circuit to ground" is reset.
Diagnostics Short-Circuit to L+
Enable diagnostics (for one DIQ channel or all DIQ channels).
You can enable diagnostics for an activated digital output.
The diagnostics monitors the digital output and signals when a short-circuit of the digital output
to L+ occurs.
