C Transducer block
This section contains information on the flowmeter transducer block. Descriptions of all
transducer block parameters, errors, and diagnostics are listed. Also, the modes, alarm
detection, status handling, application information, and troubleshooting are discussed.
Quick transducer block configuration guide
Proper configuration of the flowmeter is essential for accurate performance. The following
is a quick configuration guide for those already familiar with magnetic flowmeters.
For most parameters configured in the flowmeter, the transmitter must perform extensive
calculations to derive internal parameters used to accurately measure flow. It is
recommended that each parameter in the Transducer Block be configured and sent to the
transmitter individually. If too many parameter changes are sent to the transmitter at one
time, the transmitter will return an error. The parameters not accepted will have to be re-
sent.

Description
Static Revision. Incremented when parameter changed.
Static Tag. ASCII character string.
Can be used to help group the blocks. Not checked or processed by
the block.
ID number of the transmitter. May be used on the host for sorting
alarms.
Mode of the record of the block. Contains the actual, target,
permitted and normal modes.
Reflects the error status associated with hardware or software
components associated with a block.
Update event
Block Alarm
Directory that specifies the number and starting indices of the
transducers in the transducer block
Identifies the transducer
The version of the transducer identified by TRANSDUCER_TYPE in
the form 0xAABB where AA is the major revision of the transducer
specification on which the transducer is based, and BB is a revision
number assigned and controlled by the manufacturer of the device.
Transducer Error
A directory that specifies the number, starting indices, and DD Item
ID's of the data collections in each transducer within a transducer
block.
