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, 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
BLOCK_ERR: This parameter reflects the error status
associated with the hardware or software components associ-

may be shown.
OUT1: The block output value and status.
OUT2: The block output value and status.
X_RANGE: The display scaling of the variable correspond-
ing to the x-axis for display. It has no effect on the block.
Y_RANGE: The display scaling of the variable correspond-
ing 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.
IN1: The block input value and status.
IN2: 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 configura-
tion, hardware, connection failure, or system problems in
the block.
