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.

Abbreviations and definitions

AR Alert Record

Configuration

Variables

Variables which represent nonvolatile values of manufacturinginitialized data or userspecified

configuration information. These variables cannot be enumerated via Command 54 and as such

stand on their own with no associated units or range information.

Device Variable

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.

Enumeration A pre-defined set of values or text.

MV Measured Variable, a physical input to the instrument.

NV Named Variable – a logical point inside the device, hardmapped to a given MV as the source of

NV data.

Point 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.

Byte An 8bit unsigned integer.

Word A 16bit unsigned integer.

Float Refers to the IEEE 754 floating point format.

Packed ASCII A special form of characters defined by HART in which 6bit ASCII characters are packed into byte

data.

Standard Span

Format

A proprietary 16bit 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 twowire 4to20 mA current loop (in pointtopoint mode) or 24 VDC (in

multidrop 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.

Internal Jumpers And Switches

The input to the DVC5000 is determined by the PtPt/MultiDrop switch on the printed wiring board.

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

72, 3 Field Device Malfunction

Set / cleared by the firmware based on self test results.

This bit is set if the pressure, position or temperature

sensors provide invalid readings.

62, 3 Configuration Changed

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.

52, 3 Cold Start

Set by the firmware whenever a RESET sequence is

executed or at initial device power up. Cleared by the

first HART command.

42, 3 More Status Active when any bit in command 48 is active.

2Not Used

3Analog Input Fixed

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.

22Analog Input Saturated

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.

3Not Used

12, 3 Internal Sensor Out of Limits

(This bit is named “NonPrimary 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.

02, 3 Loop Current Out of Range Set when any variable 0 (Analog Input) is saturated.
