Number 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 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.
