™
ST_REV
: a read only parameter that gives the revision level
of the static data associated with the block. This parameter
will be incremented each time a static parameter attribute
value is written and is a vehicle for tracking changes in static
parameter attributes.
TAG_DESC
: a user assigned parameter that describes the
intended application of any given block.
STRATEGY:
a user assigned parameter that identifies
groupings of blocks associated with a given network connec-
tion or control scheme.
ALERT_KEY
: a user assigned parameter which may be used
in sorting alarms or events generated by a block.
MODE_BLK
: a structured parameter composed of the
actual mode, the target mode, the permitted mode(s), and
the normal mode of operation of a 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
PV
: Either the primary analog value for use in executing the
function, or a process value associated with it.
OUT
: The primary analog value calculated as a result of
executing the function block.
SIMULATE
: Allows the transducer analog input or output
to the block to be manually supplied when simulate is
enabled. When simulate is disabled, the simulate value and
status track the actual value and status. Please refer to
Section 2.4.5 for additional information.
XD_SCALE
: The high and low scale values, Engineering
Units, and number of digits to the right of the decimal
point used with the value obtained from the transducer for
a specified channel.
OUT_SCALE
: The high and low scale values, Engineering
Units, and number of digits to the right of the decimal
point to be used in displaying the OUT parameter.
GRANT_DENY
: Options for controlling access of host
computers and local control panels to operating, tuning,
and alarm parameters of the block.
IO_OPTS
: Option which the user may select to alter input
and output block processing.
STATUS_OPTS
: Options which the user may select in the
block processing of status.
