Viewing Device Variables and Diagnostics
May 2013
D Temperature—The internal temperature of the instrument is displayed in either degrees Fahrenheit or Celsius.
D Maximum Recorded Temperature—Shows the maximum temperature the instrument has experienced since
installation.
D Minimum Recorded Temperature—Shows the minimum temperature the instrument has experienced since
installation.
D Cycle Counter—Displays the number of times the valve travel has cycled. Only changes in direction of the travel after
the travel has exceeded the deadband are counted as a cycle. Once a new cycle has occurred, a new deadband
around the last travel is set. The value of the Cycle Counter can be reset from the Cycle Count Alert menu. See page
65 for additional information.
D Travel Accumulator—Contains the total change in travel, in percent of ranged travel. The accumulator only
increments when travel exceeds the deadband. Then the greatest amount of change in one direction from the
original reference point (after the deadband has been exceeded) will be added to the Travel Accumulator. The value
of the Travel Accumulator can be reset from the Travel Accumulator menu. See page 66 for additional information.
Note
The following should only be used for a relative indication to be sure the travel sensor is working and that it is detecting movement
of the magnet assembly.
D Raw Travel Input—Indicates the magnet assembly position in analog‐to‐digital converter counts. When the travel
sensor is operating correctly, this number changes as the valve strokes.
D View Number of Days Powered Up—Indicates in hours or days the total elapsed time the instrument has been
powered up.
D Number of Power Ups—Indicates how many times the instrument has cycled power.
Device Information
The Device Information menu is available to view information about the instrument, including; HART Tag, Device ID,
Manufacturer, Model, Device Revision, Firmware Revision, Hardware Revision, Instrument Level, and HART Universal
Revision.
D Hart Tag—A HART tag is a unique name (up to eight characters) that identifies the physical instrument.
D Device ID—Each instrument has a unique Device Identifier. The device ID provides additional security to prevent this
instrument from accepting commands meant for other instruments.
D Manufacturer—Identifies the manufacturer of the instrument.
D Model—Identifies the instrument model.
D Device Revision—Device Revision is the revision number of the software for communication between the Field
Communicator and the instrument.
D Firmware Revision—The revision number of the firmware in the instrument.
