C.4 Register transducer block
The Register Transducer Block allows access to Database registers and Input registers of the Rosemount
™
2240S Multi-input Temperature Transmitter. This makes it possible to read a selected set of register
directly by accessing the memory location.
The Register Transducer Block is only available with advanced service.
Table C-5. Register Transducer Block Parameters
Since the Register Transducer Block allows access to most registers in the Rosemount 2240S, which
includes registers set by the Methods and Configuration screens in the Measurement Transducer Block
(see
“Measurement transducer block” on page 169 ), it should be handled with care and ONLY to be
changed by trained and certified service personnel, or as guided by Emerson Automation Solutions/
Rosemount Tank Gauging support personnel.

Number
Parameter Description
1 ST_REV The revision level of the static Bdata associated with the
function block. The revision value increments each time a
static parameter value in the block is changed.
2 TAG_DESC The user description of the intended application of the
block.
3 STRATEGY The strategy field can be used to identify grouping of
blocks. This data is not checked or processed by the block.
4 ALERT_KEY The identification number of the plant unit. This
information may be used in the host for sorting alarms, etc.
5 MODE_BLK 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
6 BLOCK_ERR 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.
7 UPDATE_EVT This alert is generated by any change to the static data
8 BLOCK_ALM 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.
9 TRANSDUCER_DIRECTORY Directory that specifies the number and starting indices of
the transducers in the transducer block.
10 TRANSDUCER_TYPE Identifies the transducer.
11 TRANSDUCER_TYPE_VER
12 XD_ERROR A transducer block alarm sub code.
