Creating a Device Placeholder
Device support files must be installed before you can add a device to the segment or create a device placeholder. The DeltaV system includes built-in support for a number of fieldbus devices from different device manufacturers. The files necessary to support these devices are included in the DeltaV install image and are available in the DeltaV Explorer library (DeltaV System / Library / Fieldbus Devices). If a fieldbus device is not included in the DeltaV install image, you must install a set of device support files for that device. Many device files that have been tested with the DeltaV system are available from the main DeltaV website under Resources. If the device files that you require are not available on the website, contact the device manufacturer. Refer to the Device Descriptions and Methods topic for information on how to install device support files.
About Device Placeholders A device placeholder is an electronic representation of a device that exists in the DeltaV database with no associated physical device. You can use a placeholder to configure block parameters offline and have your control strategy in place prior to attaching the device to the segment. When you are ready, you can attach the device to the segment and use the DeltaV system to reconcile any differences between the placeholder and the device when you commission the device.
Note The use of placeholders is optional and depends on the size and requirements of your fieldbus application. However, it is recommended that you use placeholders for large applications. If you do not want to use placeholders, you can attach your devices directly to the segment.
Fieldbus devices often provide error detection for a variety of device conditions. Refer to Device Alarms Overview and Configuring Device Alarms for more information. Select the Alarms and Displays tab in the Fieldbus Device Properties dialog to enable Device Alarms to be reported by the device.
Note The alarms and displays tab is only shown when supported by the DeltaV hardware. Device alerts are supported by Series 2 H1 cards.
Each device can also be configured with a primary control display and faceplate. DeltaV software includes a standard device faceplate.

Commissioning with the DeltaV Explorer and the Device Commissioning Wizard
If the device is not in Standby, select the device in the right pane, click the right mouse button, and select Standby. It may take a minute or so for the device to transition to Standby.
The Device Commissioning Wizard - Start opens.
It may take a little while to commission the device. Several factors contribute to the time it takes to commission. Among these are the number of function blocks and devices and the time it takes for devices to move through the various device states.
Automatically Commissioning Fieldbus Devices
The DeltaV system supports the automatic commissioning of Fieldbus devices when AMS Device Manager is installed. When fieldbus device auto-commissioning is enabled as a DeltaV system property on the ProfessionalPLUS workstation, it is possible to automatically commission a fieldbus device on a segment by simply attaching the device to the segment as long as the device to be commissioned matches the manufacturer, type, revision, and device tag of a configured device placeholder in the DeltaV Explorer. Refer to Creating a Device Placeholder for more information.
Note It is important that the placeholder is created before the device is attached to the segment. The device will fail to commission if it is connected to the segment before the placeholder is created.
To enable automatic fieldbus commissioning, select the active database in the DeltaV Explorer, select Properties from the context menu, and select the Enable Fieldbus Device Auto-commissioning option. The active database is at the top level in the DeltaV Explorer hierarchy. An icon depicting a factory is used to indicate the active database. By default the active database is DeltaV_System.
Was the problem resolved? Did the device appear under "decommissioned devices"? If not I can provide a list of points to check
