OPERATION
Each F
OUNDATION
fieldbus host or configuration tool has different ways of
displaying and performing operations. Some hosts will use Device
Descriptions (DD) and DD Methods to complete device configuration and will
display data consistently across platforms. The DD can found on
www.rosemount.com. There is no requirement that a host or configuration tool
support these features.
The information in this section will describe how to use methods in a general
fashion. In addition, if your host or configuration tool does not support
methods this section will cover manually configuring the parameters involved
with each method operation. For more detailed information on the use of
methods, see your host or configuration tool manual.
Master Reset Method
To perform a master reset, run the Master Reset Method. If your system does
not support methods, manually configure the Resource Block parameters
listed below:
1.
Set the RESTART to one of the options below:
a. Set Run to nominal state when not restarting (default)
b. Resource is not used by device
c. Defaults set all device parameters to FOUNDATION Fieldbus
default values
d. The Processor does a software reset of the CPU
Sensor Transducer Block
Sensor Calibration, Upper and Lower Trim methods.
In order to calibrate the transmitter, run the Upper and Lower Trim Methods. If
your system does not support methods, manually configure the Transducer
Block parameters listed below.
1.
Set MODE_BLK.TARGET to OOS.
2.
Set CAL_UNIT to supported engineering units in the Transducer
Block.
3.
Apply physical pressure that corresponds to the lower calibration
point and allow the pressure to stabilize. The pressure must be
between the range limits defined in PRIMARY_VALUE_RANGE.
4.
Set values of CAL_POINT _LO to correspond to the pressure applied
to the sensor.
5.
Apply pressure, upper cal point.
6.
Set CAL_POINT_HI.
NOTE
CAL_POINT_HI must be within PRIMARY_VALUE_RANGE and greater than
CAL_PO CAL_MIN_SPAN
7.
Set SENSOR_CAL_DATE to the current date
8.
Set SENSOR_CAL_WHO to the person responsible for the
calibration
9.
Set SENSOR_CAL_LOC to the calibration location
10. Set SENSOR_CAL_METHOD to User Trim
11. Set MODE_BLK.TARGET to AUTO
