LOGIC TRANSDUCER
PARAMETERS
Table C-3. Logic Transducer Parameters and Descriptions
Number Parameter Description
1 ST_ REV The revision level of the static data associated with the function block.
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.
4 ALERT_ KEY The identification number of the plant unit.
5 MODE_ BLK The actual, target, permitted, and normal modes of the block. For further description, see the Mode
parameter formal model in FF-890.
6 BLOCK_ ERR This parameter reflects the error status associated with the hardware or software components associated
with a block. Multiple errors may be shown. For a list of enumeration values, see FF-890, Block_ Err
formal model.
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 attribute. 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
A directory that specifies the number and starting indices of the transducers in the transducer block. For
further information, please refer to the Transducer Block Application Process - Part 1 (FF-902)
specification.
10 TRANSDUCER_
TYPE
Identifies the transducer that follows.
11 XD_ ERROR One of the error codes defined in FF-903 XD_ ERROR and Block Alarm Subcodes.
12 COLLECTION_
DIRECTORY
A directory that specifies the number, starting indices, and DD item IDs of the data collections in each
transducer within a transducer block. For further information, please refer FF-902.
