Communication

Detailed Setup

The DVC2000 digital valve controller has the capability to communicate via the HART protocol. This section describes
the advanced features that can be accessed with the Field Communicator. Table 2‐1 lists the default settings for a
standard factory configuration. Table 2‐2 provides the actuator information required to setup and calibrate the
instrument.

Setting Modes

Instrument Mode

You can change the instrument mode by selecting Instrument Mode from the Mode menu, or press the Hot Key and
select Instrument Mode.
Instrument Mode allows you to either take the instrument Out Of Service or place it In Service. Taking the instrument
Out Of Service allows you to perform instrument calibration and also allows you to change setup variables that affect
control, provided the calibration/configuration protection is properly set. See Setting Protection.
Note
Some changes that require the instrument to be taken Out Of Service will not take effect until the instrument is placed back In
Service or the instrument is restarted.

Control Mode

You can change the control mode by selecting Control Mode from the Mode menu, or press the Hot Key and select
Control Mode.
Control Mode lets you define where the instrument receives its set point. Follow the prompts on the Field
Communicator display to choose one of the following control modes: Analog or Digital.
Choose Analog if the instrument is to receive its set point over the 4-20 mA loop. Normally the instrument control
mode is Analog.
Choose Digital if the instrument is to receive its set point digitally, via the HART communications link.
A third mode, Test, is also displayed. Normally the instrument should not be in the Test mode. The Field
Communicator automatically switches to this mode whenever it needs to stroke the valve, for example during
