Parameter Description
1 ST_REV 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.
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 2230 transducer block does not support update of
BLOCK_ALM information, and it does not publish BLOCK_ALM
on segment/FF bus.
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 subcode. Provides additional error
codes related to transducer blocks.
13 COLLECTION_DIRECTORY A directory that specifies the number, starting indices, and DD
Item ID’s of the data collections in each transducer within a
transducer block.
