• If you selected a Listen-Only communication format when you created the
module, this tab is not available.
• If HART is not enabled for this channel, Channel Not HART Enabled is
displayed.
• If HART is enabled, but the HART Field Device is not responding,
HART initializing is displayed.

Parameter Description
Channel Click a channel to display the parameters for the corresponding channel.
Refresh Click to update all attributes displayed on this tab for the corresponding channel.
Tag Displays the tag name of the HART Field Device. The tag name is entered into the Field Device to
indicate its location and purpose in the plant.
Message Displays the text that was entered in the Message parameter of the HART Field Device. The use
of this parameter can vary. One possible use is to store information such as who last calibrated
the device, or reference to documentation.
Descriptor Displays the Descriptor field from the HART Field Device. The Descriptor is a text message that
can be stored in the device to help identify the device or it can be used for other plant specific
purposes.
Date Displays the date entered in the device. This date is often used to record the last calibration
date, but it is up to the end user to maintain it. It is displayed in the format selected for your
computer using the Regional and Language settings on the Control Panel.
Write Protect Displays a Yes or No indicating if the HART Field Device is write protected. If a device is write
protected, some parameters cannot be changed via HART communication. Note that
sometimes devices do not indicate that the configuration changed when their write-protect
setting changes. This causes the previous value to remain displayed here. You can inhibit/
uninhibit the HART module to refresh this.
Manufacturer ID Displays the manufacturer name (for example, Allen-Bradley or Endress + Hauser) or the
numeric value for the manufacturer. Use the Company Identification Code table as a guide, as
shown in Appendix E.
Device Type Displays the device type for Endress + Hauser devices or a numeric value for all other
manufacturer devices. Device type indicates the manufacturer's type of the device, or product
name. For example, Cerabar S pressure transmitters from Endress + Hauser have Device Type 7.
Device ID Displays a number that represents the device ID. Device ID is a serial number assigned by the
manufacturer that is unique among all devices produced by that manufacturer.
Final Assembly Displays a number that represents the final assembly number. The Final Assembly Number is
Number used for identifying the materials and electronics that comprise the field device. It is normally
changed when electronics or other components are upgraded in the field. In some instances,
this number references a drawing number.
