Configuration
parameters
The parameters listed in the following table are manufacturer-specific and can be
used to configure the device as described in Chapter 5 and 6. Refer also to Fig.: 3.4.
The transducer block also contains standard profile parameters. Some of these, e.g.
CAL_POINT_HI and CAL_POINT_LO can be changed but have no effect on the
device. If the user desires, however, he can enter data relevant to the calibration in
the SENSOR_CAL_ parameters and enter a tag description for the transducer block in
TAG_DESC.
Parameter Description
MODE_BLK
See description in Resource block.
The possible operating modes of the transducer block are:
AUTO: the block is operating as normal.
MAN: the block is operated with a manually entered primary value.
OOS: the block is out of service.
TAG_DESC
User description of the intended application of the block.
BLOCK_ERROR
Shows the error status associated with the block components
Out-of-Service: the block is in OOS mode.
Simulation active: shows the setting of DIP-switch WP.
Input failure/process variable has BAD status.
Parameter Description
PRIMARY_VALUE
Primary value output by transducer block, here it is pressure or
linearization value
SECONDARY_
VALUE
Secondary value output by transducer block, here it is temperature
Parameter Description
Measured Value *
Indicates the current value measured by the device.
Lower Range
Value
Entry of pressure for lower range-value – zero, (affects bargraph)
Upper Range
Value
Entry of pressure for upper range-value – span, max. turndown 20:1
(affects bargraph)
Set Lower Range
Value
Acting pressure is taken as lower range-value – zero, (affects bargraph)
Set Upper
Range Value
Acting pressure is taken as lower range-value – span,
max. turndown 20:1, (affects bargraph)
Set Bias
Pressure
Entry of bias pressure, parameter "Biased Pressure" adopts the new value.
Operating mode "linear" (pressure): Display correction for parameters
"Measured Value", "Upper Range Value" and "Lower Range Value"
Bias Pressure
Automatically
Acting pressure is taken as bias pressure, parameter "Biased Pressure"
adopts the new value.
Operating mode "linear" (pressure): Display correction for parameters
"Measured Value", "Upper Range Value" and "Lower Range Value"
Set Output
Damping
Sets the damping time for the transducer block output signal (Primary
Value), Range: 0 - 40 s
