Note
Do not use the following raw travel
input indication for calibrating the
travel sensor. The following should
only be used for a relative indication to
be sure the travel sensor is working
and that it is moving in the correct
direction. Perform the Travel Sensor
Adjust procedure in the Calibration
section to calibrate the travel sensor.
 Raw Travel Input—Raw travel input indicates
the travel sensor position in analog-to-digital converter
counts. When the travel sensor is operating correctly,
this number changes as the valve strokes.
 View Number of Days Powered Up—Indicates
in hours or days the total elapsed time the instrument
has been powered up.
 Number of Power Ups—Indicates how many
times the instrument has cycled power.
Device Information (3-7)
The Device Information menu is available to view
information about the instrument. From the Online
menu, select Overview and Device Information. Follow
the prompts on the Field Communicator display to
view information in the following fields:
 Hart Tag—A HART tag is a unique name (up to
eight characters) that identifies the physical
instrument.
 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.
Table 6-2. Functions Available for Instrument Level
Functions Available
Communicates with Field Communicator and ValveLink software.
Provides: travel cutoffs and limits, minimum opening and closing
times, input characterization (linear, equal percentage, quick opening,
and custom), trending with ValveLink Solo, and the following alerts:
travel deviation; travel alert high, low, high high, and low low; drive
signal; auxiliary terminal; cycle counter; and travel accumulation. With
ValveLink Software, all offline diagnostic tests (dynamic error band,
drive signal, step response, and valve signature) plus online trending
and partial stroke test
 Manufacturer—Identifies the manufacturer of
the instrument.
 Model—Identifies the instrument model.
 Device Revision—The revision number of the
software for communication between the Field
Communicator and the instrument.
 Firmware Revision—The revision number of the
firmware in the instrument.
 Hardware Revision—The revision number of the
electrical circuitry within the instrument printed wiring
board.
 Instrument Level—Indicates the instrument
level − SIS
Table 6-2 lists the functions available instrument level
SIS.
 HART Univeral Revision—The revision number
of the HART Universal Commands which are used as
the communications protocol for the instrument.
DD Information (3-8)—DD Information contains the
device description in the Field Communicator. To
access DD Information from the Online menu, select
Overview and DD Information.
