Introduction
Product Overview
The FIELDVUE DVC6200 SIS digital valve controller is designed to control the pneumatic actuator of a safety 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 safety valve is measured by the DVC6200 SIS travel
sensor as its primary feedback. The name plate is located on the bottom side of the DVC6200 SIS 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 DVC6200 SIS product literature, available from Emerson Process Management.

Product Interfaces
Control Valve Interface
The DVC6200 SIS digital valve controller is mechanically attached to the valve’s actuator by means of a mounting
bracket. The valve's position is conveyed to the travel sensor of the DVC6200 SIS digital valve controller by means of
the feedback bracket and magnet assembly attached to the actuator’s stem.

AND MAGNET ASSEMBLY
X0381-1
Pneumatic tubing connected to the DVC6200 SIS brings instrument supply air to the DVC6200 SIS and takes
controlled output air from the DVC6200 SIS to the actuator. Pressure sensors in the DVC6200 SIS measure these
pressure signals and present them as device variables
Host interface
The input to the DVC6200 SIS can either be twowire 4to20 mA current loop (in pointtopoint mode) or 24 VDC (in
multidrop mode). This input is connected in the DVC6200’s terminal box on two terminals marked “LOOP +” and
“LOOP ”. Refer to the DVC6200 Series quick start guide for connection details.
Pushbutton Calibration
A pushbutton near the wiring terminals in the terminal box provides a quick means to autocalibrate the travel of the
instrument. The button must be pressed for 3 to 10 seconds. Autocalibration will move the valve through the full
range of travel whether the Instrument Mode is In Service or Out of Service. However, if the Write Protection is
Protected, this button will not be active. To abort, press the button again for 1 second. The calibration button is
disabled by default.

Internal Jumpers And Switches
The input to the DVC6200 SIS is determined by the PtPt/MultiDrop switch on the printed wiring board.
The DVC6200 SIS also has a pair of “Output” terminals that can either function as a position transmitter or a discrete
switch. Electronic configuration of the output circuit requires the proper setting of a DIP switch on the DVC6200’s
printed wiring board. Additionally, the functional operation of the output circuit must be configured with the user
interface.

SELECTION
The DVC6200 SIS has an analog shutdown circuit built into the electronics construction. This circuit enables the
DVC6200 SIS to perform the safety function through electronics hardware, independent from the device firmware.
This function is controlled by two DIP switches:
One switch enables or disables the hardware shutdown feature.
The other switch to choose either to deenergizetotrip (labeled “Trip Current Low (DETT)”) or energizetotrip
(labeled “Trip Current High (ETT)”).
The cutoff point is 12 mA +/ 5% and is not configurable. DETT is the standard configuration for direct acting
applications. Energizetotrip (ETT) is the standard configuration for reverse acting applications.
Refer to the DVC6200 SIS instruction manual for additional details on the settings of the selection switches.
Write Protection
There are two Write Protection states for the DVC6200 SIS: 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 press a button inside
the terminal box when directed by the software as a security measure.

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 Name of Status Bit Meaning
7Field 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.
6Configuration 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.
5Cold Start
Set by the firmware whenever a RESET sequence is executed or at initial
device power up. Cleared by the first HART command. Two such bits exist
internally, one for each HART master.
4More Status Active when any bit in command 48 is active.
3Analog Input Fixed
Active if the Instrument Mode of the DVC6200 SIS is in the “Out Of Service”
condition or if the Control Mode of the DVC6200 SIS is in one of the digital
set point modes.
2Analog Input Saturated The loop current reading is beyond sensor limits.
1Internal Sensor Out of Limits
(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.
0Variable Out of Range Set when any variable 0, 1, 2, 3, 5, 8 or 10, is saturated.

Command 15: Read Primary Variable Output Information
This command returns the upper/lower range values for the primary variable which is defined to be the loop current
signal. These are the loop current values for the ends of physical travel, and are used to derive set point from the loop
current. It reports the range supplied in Command 35.
For example, the lower range, for an increase to open valve, will be the current which will produce a 0% set point.
However, for an increase to close valve, the lower range will be the loop current for a 100% set point.
The range values can be changed via Command 35.
The DVC6200 SIS assumes 0% = 4mA and 100% = 20mA.

Command 35: Write Primary Variable Range Values
In the DVC6200 SIS, the Primary Variable is defined to be the Analog Input (loop current).
This command is used to write the ranging values reported in Command 15. It controls how the DVC6200 SIS
interprets the loop current when creating the Travel Target. The upper range must be greater than the lower range.
This command does units conversion, accepting range values in milliamps or percent. If the primary variable is not
configured to use the same units as supplied in this command, the supplied ranges will be converted to PV units before
being applied. Range values are validated against those reported in Command 14 to assure that they are within the
allowable range and are separated by a minimum span.
If the range values are in percent, then they are assumed to be percent of 420 mA. For example, to range an increase
to open unit from 8 mA to 16 mA, but using percent range numbers, specify lower_range = 25% and upper_range =
75%.
This ranging is done in conjunction with the zero power condition. For an IncreasetoOpen valve, the lower range is
the 0% setpoint level (valve plug in the valve seat), while the upper range is the 100% setpoint level. An
IncreasetoClose valve is exactly opposite.
This command will be accepted when the DVC6200 SIS’s Instrument Mode is In Service but will be rejected if Write
Protection is in effect.

Command 42: Perform Master Reset
This reset command has two options. If no data bytes are supplied, respond immediately and then perform a “warm”
reset. This is not equivalent to power up in that restart modes and default IVP are not adopted and the realtime clock
is not reset. All other data is read from nonvolatile memory and put into effect. The second option is hard reset. This
requires two data bytes set as described below. If this form is received, the unit will save modes and counters, then
execute a hard reset by exercising the watchdog timer. The next response will have the “cold_start” bit set.
A “soft reset” command will be honored while the DVC6200 SIS Instrument Mode is in the “In Service” condition.
A “hard reset” command requires the DVC6200 SIS Instrument Mode be in the “OutofService” condition.

Command 44: Change Primary Variable Units Code
This command is issued to change the units of the Primary Variable, which is defined in the DVC6200 SIS as the Analog
Input (loop current). The choices for units are Percent (code 57) or Milliamps (code 39). This command will cause
variable 0 (loop current), and the response to Command 14, to be reported in the new units.
In addition to changing the units code, execution of this command will also change the DVC6200 SIS’s Analog Input
Upper and Lower Range values to reflect the new units. (For example: When the DVC6200 SIS’s Analog Input is
configured as “420 mA” and Command 44 with request Data Byte 57 is executed, the DVC6200 SIS’s Analog Input
units and range values will change to “0100%”. Likewise, when the DVC6200 SIS’s Analog Input is configured as
“0100%” and Command 44 with request Data Byte 39 is executed, the DVC6200 SIS’s Analog Input units and range
values will change to “420 mA”).
This command will be accepted when the DVC6200 SIS’s Instrument Mode is In Service, but will be rejected if Write
Protection is in effect.

Annex B DVC6200 SIS Parameters as part of a Rosemount 1410 /
1420 WirelessHART Gateway
A FIELDVUE DVC6200 SIS 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 DVC6200 SIS from
application software and as an independent master issuing commands periodically to the wired device pertaining to
it’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.
For HART 7 devices up to 8 variables can be mapped.
Configure the THUM as follows:
HART 5 - select PV, SV, TV, and QV
HART 7 - select Process Variables with Variable Status
Choose Variables 0, 1, 2, 4, 6, 8, 9, and 10
Select Yes if changes are required
Both HART 5 and HART 7 - select Device Status
Navigate to Configure > Manual Setup
