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.

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.

Instruction Manual Supplement

D103266X012

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

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.

(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.

Annex B DVC5000 Parameters as part of a Rosemount 1410 / 1420 WirelessHART Gateway

A FIELDVUE DVC5000 can join a wireless network through the addition of a Rosemount 775 THUM WirelessHART adapter. The wireless adapter acts both as a HART modem for communications coming to the DVC5000 from application software and as an independent master issuing commands periodically to the wired device pertaining to the device’s status. This independently gathered status information is relayed back to the Rosemount 1410 or 1420 Wireless Gateway and is made available to the user either through viewing the HTML interface or via mapping as “Published Data” parameters via the Gateway’s MODBUS or OPC outputs.

For HART 5 devices the PV, SV, TV, and QV variables can be mapped.

Configure the THUM as follows:

Navigate to Configure > Manual Setup Under the Wired Device tab select Configure HART Polling

Select Yes if changes are required

Wired Device tab

FOR PRIMARY DEVICE INFORMATION:

Select PV, SV, TV, and QV

FOR SECONDARY DEVICE INFORMATION:

Select Device Status
