Scope of Manual
This instruction manual includes specifications,
installation, operating, and maintenance information
for the DVC6200f digital valve controller.
This manual describes device setup using the 475 or
375 Field Communicator. For information on using
Fisher ValveLink software with the instrument, refer to
the appropriate user guide or help.
Do not install, operate, or maintain a DVC6200f digital
valve controller without being fully trained and qualified
in valve, actuator, and accessory installation,
operation, and maintenance. To avoid personal injury
or property damage, it is important to carefully read,

Instrument Description
DVC6200f digital valve controllers for F
OUNDATION
fieldbus are communicating, microprocessor-based
instruments. In addition to the traditional function of
converting a digital signal to a pneumatic output
pressure, the DVC6200f digital valve controller, using
F
OUNDATION
fieldbus communications protocol, gives
easy access to information critical to process
operation as well as process control. This can be done
using a DeltaV
console, another F
OUNDATION
fieldbus
system console, or with ValveLink software version
10.2 or later.
Using a compatible fieldbus configuration device, you
can obtain information about the health of the
instrument, the actuator, and the valve. You can also
obtain asset information about the actuator or valve
manufacturer, model, and serial number. You can set
input and output configuration parameters and
calibrate the instrument.

Mounted on a Fisher Sliding-Stem Valve Actuator
Using the F
OUNDATION
fieldbus protocol, information
from the instrument can be integrated into control
systems.
DVC6200f digital valve controllers can be mounted on
single or double-acting sliding-stem actuators, as
shown in figure 1-1, or on rotary actuators. It can also
be integrally mounted to the Fisher GX control valve
and actuator system, as shown in figure 1-2. The
DVC6200f mounts on most Fisher and other
manufacturers’ rotary and sliding-stem actuators.
DVC62000f digital valve controllers are available with
several selections of control and diagnostic capability.
Control selections include:
Standard Control (SC)— Digital valve
controllers with Standard Control have the AO, PID,
ISEL, OS, AI, MAI, DO, and four DI function blocks in
addition to the resource and transducer blocks.
Fieldbus Control (FC)—Digital valve controllers
with Fieldbus Control have the AO function block in
addition to the resource and transducer blocks.
Fieldbus Logic (FL)—Digital valve controllers
with Fieldbus Logic have the DO, and four DI function
blocks, in addition to the resource and transducer
block.
The diagnostic capabilities include:
Performance Diagnostics (PD)
