Parameter Description
BYPASS Used to override the calculation of the block. When enabled, the SP
is sent directly to the output.
CAS_IN The remote setpoint value from another block.
SP_RATE_DN Ramp rate for downward SP changes. When the ramp rate is set to
zero, the SP is used immediately.
SP-RATE_UP Ramp rate for upward SP changes. When the ramp rate is set to
zero, the SP is used immediately.
SP_HI_LIM The highest SP value allowed.
SP_LO_LIM The lowest SP value allowed.
GAIN The proportional gain value. This value cannot = 0.
RESET The integral action time constant.
BAL_TIME The specified time for the internal working value of bias to return to
the operator set bias. Also used to specify the time constant at
which the integral term moves to obtain balance when the output is
limited and the mode is AUTO, CAS, or RCAS.
RATE The derivative action time constant.
BKCAL_IN The analog input value and status from another block’s
BKCAL_OUT output that is used for backward output tracking for
bump less transfer and to pass limit status.
OUT_HI_LIM The maximum output value allowed.
OUT-LO_LIM The minimum output value allowed
BKCAL_HYS The amount the output value must change away from its output limit
before limit status is turned off.
BKCAL_OUT The value and status required by the BKCAL_IN input of another
block to prevent reset windup and to provide bump less transfer of
closed loop control.
RCAS_IN Target setpoint and status that is provided by a supervisory host.
Used when mode is RCAS.
ROUT_IN Target output and status that is provided by a supervisory host.
Used when mode is ROUT.
SHED_OPT Defines action to be taken on remote control device timeout.
RCAS_OUT Block setpoint and status after ramping, filtering, and limiting that are
provided to a supervisory host for back calculation to allow action to
be taken under limiting conditions or mode change. Used when
mode is RCAS.
ROUT_OUT Block output that is provided to a supervisory host for a back
calculation to allow action to be taken under limiting conditions or
mode change. Used when mode is RCAS.
TRK_SCALE The high and low scale values, engineering units code, and number
of digits to the right of the decimal point associated with the external
tracking value (TRK_VAL).
TRK_IN_D Discrete input that initiates external tracking.
