Parameter Description
ST_REV The revision level of the static data associated with the function block. The
revision value is incremented each time a static parameter value in the
block is changed.
TAG_DESC The use description of the intended application of the block.
STRATEGY The strategy field can be used to identify grouping of blocks. This data is
not checked or processed by the block.
ALERT_KEY The identification number of the plant unit. This information may be used
in the host for sorting alarms, etc.
MODE_BLK The actual, target, permitted, ad 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
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.
OUT_1 The block output value and status.
OUT_2 The block output value and status.
X_RANGE The display scaling of the variable corresponding to the x-axis for display.
It has no effect on the block.
Y_RANGE The display scaling of the variable corresponding to the y-axis for display.
It has no effect on the block.
GRANT_DENY Options for controlling access of host computers and local control panels
to operating, tuning, and alarm parameters of the block. (Not used by the
device)
IN_1 The block input value and status.
IN_2 The block input value and status.
SWAP_2 Changes the algorithm in such a way that IN_2 corresponds to “y” and
OUT_2 to “x”.
CURVE_X Curve input points. The “x” points of the curve are defined by an array of
21 points.
CURVE_Y Curve input points. The “y” points of the curve are defined by an array of
21 points.
UPDATE_EVT This alert is generated by any changes to the static data.
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 sets the active status in the
status parameter. As soon as the Unreported status is cleared by the alert
reporting task other block alerts may be reported without clearing the
active status, if the subcode has changed.
