General Description
2.2.4 Field Device Handling
The ADM differentiates between "configured" and "unconfigured" field devices. Field devices
are identified based on the device address.
• Configured field devices
The ADM features a list of field devices that are labeled "configured field devices". All field
devices (and the hosts) belonging to the segment are added to the configured field
devices list. Field devices included in this list can have a tag, limits for their signal levels,
as well as alarm settings for field-device-specific alarms. The commissioning wizard auto-
matically includes all field devices that are active during the commissioning procedure in
the configured field devices list. If field devices are active on the fieldbus and are not in the
configured field devices list or devices in the list are inactive (i.e., not communicating), the
ADM issues an alarm.
• Unconfigured field devices
All devices that are active on the fieldbus, but are not in the configured field devices list
are labeled "unconfigured field devices". All measured physical layer data (e.g., signal lev-
els) is shown for this device, but no alarms etc. are associated with this device.
