Parameter list
Table 24: Signal Characterizer block parameters
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.
LICENSE_STATUS_SC License status of the function block.
