OUNDATION
The Measurement Transducer block contains the actual measurement data,
including a level and distance reading. The transducer block includes
information about sensor type, engineering units, and all parameters needed
to configure the transmitter.

Fieldbus Block Information
Parameter
The revision level of the static data associated
with the function block. The revision value
increments each time a static parameter value in
the block is changed.
The user description of the intended application
of the block.
The strategy field can be used to identify
grouping of blocks. This data is not checked or
processed by the block.
The identification number of the plant unit. This
information may be used in the host for sorting
alarms, etc.
The actual, target, permitted, and normal modes
of the block.
Target: The mode to "go to"
Actual: The mode the "block is currently in"
Permitted: Allowed modes that target may take
on
Normal: Most common mode for target
This parameter reflects the error status
associated with the hardware or software
components associated with a block. It is a bit
string, so that multiple errors may be shown.
This alert is generated by any change to the
static data
The block alarm is used for all configuration,
hardware, connection failure or system problems
in the block. The cause of the alert is entered in
the subcode field. The first alert to become active
will set the Active status in the Status parameter.
As soon as the Unreported status is cleared by
the alert reporting task, another block alert may
be reported without clearing the Active status, if
the subcode has changed.
Directory that specifies the number and starting
indices of the transducers in the transducer
block.
Identifies the transducer.
A transducer block alarm subcode.
A directory that specifies the number, starting
indices, and DD Item ID's of the data collections
in each transducer within a transducer block.
