Transducer Block

This section contains information on the DVC6200f
digital valve controller transducer block. Descriptions
of all transducer block parameters are included. The
transducer block decouples function blocks from the
local output functions required to command output
hardware. The transducer block typically contains
setup and calibration information.

Field Communicator
Instrument Alert Conditions, when enabled, detect
many operational and performance issues that may be
of interest. The alert conditions for each group of
alerts are listed below. If there are no alerts active for
a particular group the group will not be displayed on
the Field Communicator.
D Electronics—if an electronics alert is active it will
appear under ELECT ALERTS
Drive Current
Drive Current Alert—This alert is active when the
difference between the expected Drive Current and
the actual Drive Current has exceeded the Drive
Current Alert Time.
Drive Signal
Drive Signal Alert—The Drive Signal Alert is active if
one of the following conditions exist:
Where Zero Power Condition is defined as closed:
Drive Signal < 10% and Calibrated Travel > 3%
Drive Signal > 90% and Calibrated Travel < 97%
November 2010
Viewing Device Variables and Diagnostics
Where Zero Power Condition is defined as open:
Drive Signal < 10% and Calibrated Travel < 97%
Drive Signal > 90% and Calibrated Travel > 3%
Processor Impaired
Program Memory Alert—This alert is active if a
pending flash or NVM failure is present.
Static Memory Alert—This alert is active when there
is a failure of the FRAM memory where static
parameters are stored.
Processor Alert—This alert is active when there is a
failure of the main processor.
I/O Processor Alert—This alert is active when there
is a failure of the I/O processor.
D Configuration—If a configuration alert is active
it will appear under CONFIG ALERTS
Output Block Timeout
Output Block Timeout Alert—This alert is active if
the output block has not executed for a period of time
longer than the configured timeout.
Blocks Set to Default
Blocks Set to Default Alert—This alert is active if the
resource block has undergone Restart with Defaults.
This will stay active until the transducer block is
changed from Out of Service.
D Sensor—If a configuration alert is active it will
appear under SENSOR ALERTS
Travel Sensor
Travel Sensor—This alert is active if the Travel
Sensor reading is outside the functional range, or the
sensor becomes disconnected.
Pressure Sensors
Pressure A Sensor Alert—This alert is active if the
Port A Pressure Sensor reading is outside the
functional range.
Pressure B Sensor Alert—This alert is active if the
Port B Pressure Sensor reading is outside the
functional range.
Supply Pressure Sensor Alert—This alert is active if
the Pressure Sensor reading is outside the functional
range.
Pressure Fallback
Pressure Fallback Alert—This alert is active if a
travel sensor failure or a gross travel deviation has
resulted in fallback to pressure control.
Temperature Sensor
Temperature Sensor Alert—This alert is active if the
temperature sensor reading is outside the functional
range of the sensor.
D Environment—If an environment alert is active it
will appear under ENVIRO ALERTS
