Introduction
Product Overview
The FIELDVUE DVC5000 digital valve controller is designed to control the pneumatic actuator of a process control
valve. It receives a current signal from a host and uses instrument air supply to create a metered pressure output signal
to the pneumatic actuator. Movement of the actuator as it positions the process control valve is measured by the
DVC5000 travel sensor as its primary feedback. The name plate is located on the side of the DVC5000 master module
assembly and indicates the model name, individual product serial number, and any applicable third party approvals.
Purpose of this document
This specification is designed to be a technical reference for HART capable host application developers, system
integrators and knowledgeable end-users. It also provides functional specifications (e.g., commands, enumerations
and performance requirements) used during field device development, maintenance and testing. This document
assumes the reader is familiar with HART Protocol requirements and terminology. Additional product information is
available in the DVC5000 product literature, available from your Emerson sales office
or Local Business Partner.

Variables which represent nonvolatile values of manufacturinginitialized data or userspecified
configuration information. These variables cannot be enumerated via Command 54 and as such
stand on their own with no associated units or range information.
Measured variables that are exposed to HART and can be enumerated using Command 54.
Generally there are variables whose ID is in the range of 0 to 10 and are associated with units
codes, status, and range values.
Named Variable – a logical point inside the device, hardmapped to a given MV as the source of
NV data.
A term that applies to diagnostic data packets. It is defined as a collection of periodically sampled
variables captured at a single instant in time. It does not include the “Monitor” point.
A special form of characters defined by HART in which 6bit ASCII characters are packed into byte
data.
A proprietary 16bit integer format for numerical values used by some of this device’s Device
Specific commands.

Product Interfaces
Control Valve Interface
The DVC5000 digital valve controller is mechanically attached to the valve’s actuator by means of a mounting bracket.
The control valve's position is conveyed to the travel sensor of the DVC5000 digital valve controller by means of the
feedback bracket attached to the actuator’s stem and the rotating travel sensor.
MOUNTING
BRACKET
Pneumatic tubing connected to the DVC5000 brings instrument supply air to the DVC5000 and takes controlled
output air from the DVC5000 to the actuator. The pressure sensor in the DVC5000 measures the output pressure and
presents it as a device variable.
Host interface
The input to the DVC5000 can either be twowire 4to20 mA current loop (in pointtopoint mode) or 24 VDC (in
multidrop mode). This input is connected in the DVC5000’s terminal box on two terminals marked “LOOP +” and
“LOOP ”. Refer to the DVC5000 instruction manual for connection details.

Write Protection
There are two Write Protection states for the DVC5000: Not Protected or Protected. Protected prevents configuration
and calibration changes to the instrument. The default setting is Not Protected. Protection is controlled under
software control. Write Protection can be enabled remotely. However, to disable Write Protection to Not Protected,
you must have physical access to the instrument. The procedure will require you to short the AUX terminals inside the
terminal box when directed by the software as a security measure.
Firmware Upgrade
The firmware of a DVC5000 printed wiring board assembly cannot be upgraded.

Status Information
Device Status
The Field Device Status Byte is the only status byte defined in the HART protocol. The order and meaning of each of the
eight bits within the byte are fixed by the protocol. This byte is one of the status bytes included with each HART
response. It is not part of the Command 48 data.
Bit Device Revision Name of Status Bit Meaning
Set / cleared by the firmware based on self test results.
7 2, 3 Field Device Malfunction
6 2, 3 Configuration Changed
5 2, 3 Cold Start
4 2, 3 More Status Active when any bit in command 48 is active.
2 Not Used
3
2
1 2, 3 Internal Sensor Out of Limits
0 2, 3 Loop Current Out of Range Set when any variable 0 (Analog Input) is saturated.
3 Analog Input Fixed
2 Analog Input Saturated
3 Not Used
This bit is set if the pressure, position or temperature
sensors provide invalid readings.
Two such bits exist internally, one for each HART master.
Both copies are set when any variable, HART message,
tag, descriptor or date are changed from HART. Cleared
by command 38, separately for each master. This bit
survives loss of power.
Set by the firmware whenever a RESET sequence is
executed or at initial device power up. Cleared by the
first HART command.
Active if the Instrument Mode of the DVC5000 is in the
“Out Of Service” condition or if the Control Mode of the
DVC5000 is in one of the digital set point modes.
Active if the Instrument Mode of the DVC5000 is in the
“Out Of Service” condition or if the Control Mode of the
DVC5000 is in one of the digital set point modes.
(This bit is named “NonPrimary Variable Out Of Limits”
in the HART documentation for transmitters. It has been
renamed to reflect the fact that these variables are
INTERNAL INPUTS to FIELDVUE products). The firmware
sets this bit when any sensor (pressure, position,
temperature) exceeds its operating limits.
