DVC2000 Digital Valve Controller Instruction Manual Supplement D103783X012 August 2014 Introduction Product Overview The DVC2000 digital valve controller is a communicating, microprocessor-based current-to-pneumatic valve positioner. It is designed to replace standard pneumatic and electro-pneumatic valve positioners.

Instruction Manual Supplement DVC2000 Digital Valve Controller D103783X012 August 2014 Product Interfaces Control Valve Interface The DVC2000 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 DVC2000 digital valve controller by means of the feedback bracket and magnet assembly attached to the actuator’s stem or rotating travel sensor.

Instruction Manual Supplement D103783X012 DVC2000 Digital Valve Controller August 2014 Output Options Circuit All three options circuits (transmitter, switch 1 and switch 2) control current from an external power source similar to the operation of a 2-wire transmitter. Limit Switches On units that are supplied with integral limit switches, additional terminals provide the field wiring connection point.

Instruction Manual Supplement DVC2000 Digital Valve Controller D103783X012 August 2014 Dynamic Variables Four Dynamic Variables are implemented. PV SV TV FV Default Meaning Analog Input Travel Setpoint Pressure Travel Units mA, % % PSI, BAR, KPA % Device Variables These variables represent measurements taken by the device, are read only values, and are all in float format. These can be read with Commands 33 and 54.

Instruction Manual Supplement DVC2000 Digital Valve Controller D103783X012 August 2014 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.

Instruction Manual Supplement DVC2000 Digital Valve Controller D103783X012 August 2014 Command 1: Read Primary Variable This command reads the value of the DVC2000’s Primary Variable, which is Analog Input (loop current). The units are either “mA” or “%” as configured in the device by Command 44.
PAGE 11
Instruction Manual Supplement DVC2000 Digital Valve Controller D103783X012 August 2014 Command 3: Read Dynamic Variables and Loop Current This command is used to read the value of Loop Current and the four Dynamic Variables. The four dynamic variables returned depend upon the variable assignment as defined by Command 51 and read back via Command 50. The default Dynamic Variable assignment and the Variable Units Codes are shown on page 6.
PAGE 12
DVC2000 Digital Valve Controller Instruction Manual Supplement D103783X012 August 2014 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.

Instruction Manual Supplement DVC2000 Digital Valve Controller D103783X012 August 2014 CommonPractice Commands The DVC2000 field device supports the following common practice commands: Supported Commands Command 33: Read Device Variables Command 35: Write Primary Variable Range Values Command 38: Reset Configuration Change Flag Command 42: Master Reset Command 44: Change Primary Variable Units Code Command 48: Read Additional Status Command 50: Read Dynamic Variable Assignments Command 54: Read Device
PAGE 14
Instruction Manual Supplement DVC2000 Digital Valve Controller D103783X012 August 2014 Command 35: Write Primary Variable Range Values In the DVC2000, 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 DVC2000 interprets the loop current when creating the Travel Target. The upper range must be greater than the lower range.
PAGE 15
Instruction Manual Supplement DVC2000 Digital Valve Controller D103783X012 August 2014 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.

Instruction Manual Supplement DVC2000 Digital Valve Controller D103783X012 August 2014 Command 50: Read Dynamic Variable Assignments This command returns a list of four device variable codes taken from table DVC Device Variables which are returned in Command 3. These Dynamic Variables are fixed and control the Command 3 response, whether burst or by request.

DVC2000 Digital Valve Controller August 2014 Instruction Manual Supplement D103783X012 Device-Specific Commands The DVC2000 field device supports devicespecific commands. However, these devicespecific commands require use of the ValveLink software application or DD methods and cannot be utilized outside of those controlled environments. Burst Mode This field device supports Burst Mode. Catch Device Variable This field device does not support Catch Device Variable.
