ABNORM_ACTIVE
|
None
|
The indication that a block error condition not selected in BAD_MASK (on the function block level) is True (Active).
|
BAD_ACTIVE
|
None
|
The indication that a block error condition selected in BAD_MASK (at the function block level) is True (Active).
|
BAD_MASK
|
None
|
The set of active error conditions that triggers a user-defined Bad condition. The user selects a subset of block error (BLOCK_ERR) conditions in the BAD_MASK parameter. When any of these conditions are True, the BAD_ACTIVE parameter becomes True. When any of the BLOCK_ERR conditions that are not included in BAD_MASK are True, ABNORM_ACTIVE becomes True.
|
BAL_TIME
|
Seconds
|
Specifies the time for dissipation of the internal balancing bias.
|
BKCAL_IN
|
EU of OUT_SCALE
|
The analog input value and status from another block's BKCAL_OUT output that is used by an upstream block for bumpless transfer.
|
BKCAL_OUT
|
EU of OUT_SCALE
|
The value and status required by the BKCAL_IN input of another block to prevent reset windup and to provide bumpless transfer to closed loop control.
|
BLOCK_ERR
|
None
|
The summary of active error conditions associated with the block. The possible block errors for the Bias/ Gain function block are:
Out of Service.
Local Override
|
CAS_IN
|
EU of PV_SCALE
|
The remote analog setpoint value from another block.
|
CONTROL_OPTS
|
None
|
Use control options to specify control strategy options. The supported control options for the Bias/Gain function block are:
No OUT limits in Manual
Obey SP lim if Cas or RCas
Use BKCAL_OUT With IN_1
Act on IR
Track in Manual
Track Enable
SP Track Retained Target.
|
FRSIRB_OPTS
|
None
|
The supported FRSIRB_OPTS option option is Treat_IN_1 As Wild. When Treat_IN_1 As Wild is true regardless of cascade or non-cascade connection IN_1 is treated as a non-cascade input and if Use_Bkcal_out_With_IN_1 is true Bkcal_out sub-status will be set to keep cascade closed.
|
GAIN
|
None
|
The multiplier applied in GAIN × (SP + IN_1).
|
IN_1
|
Determined by source
|
The input with status to which the bias (SP) is applied.
|
MODE
|
None
|
Parameter used to show and set the block operating state.
|
OUT
|
EU of OUT_SCALE
|
The block output value and status.
|
OUT_HI_LIM
|
EU of OUT_SCALE
|
The maximum output value allowed.
|
OUT_LO_LIM
|
EU of OUT_SCALE
|
The minimum output value allowed.
|
OUT_SCALE
|
None
|
The high and low scale values, engineering units code, and number of digits to the right of the decimal point associated with OUT.
|
RCAS_IN
|
EU of SP_SCALE
|
The remote setpoint value and status. Input provided by a remote device or the output of another block.
|
RCAS_OUT
|
EU of PV_SCALE
|
The output provided for bumpless mode transfer and reset limiting by the source of RCAS_IN. Essentially the equivalent of BKCAL_OUT for RCAS_IN.
|
SHED_OPT
|
None
|
Defines action to be taken on remote control device time out.
|
SP
|
EU of OUT_SCALE
|
The block's setpoint value.
|
SP_HI_LIM
|
EU of OUT_SCALE
|
The highest setpoint value allowed.
|
SP_LO_LIM
|
EU of OUT_SCALE
|
The lowest setpoint value allowed.
|
SP_RATE_DN
|
EU of OUT_SCALE per second
|
Rate of change limit for decreasing setpoint. When SP change violates the limit the effect is a ramp into the working setpoint (SP_WRK).
|
SP_RATE_UP
|
EU of OUT_SCALE per second
|
Rate of change limit for increasing setpoint. When SP change violates the limit the effect is a ramp into the working setpoint (SP_WRK).
|
SP_WRK
|
EU of OUT_SCALE
|
The working setpoint of the block. It is the result of setpoint limiting and setpoint rate of change limiting.
|
STATUS_OPTS
|
None
|
Status options determine how status is processed and handled. The available options are:
Target to Manual if Bad IN
Use Uncertain as Good
IFS if Bad CAS_IN
IFS if Bad IN
|
TRK_IN_D
|
None
|
Discrete input that initiates external tracking.
|
TRK_SCALE
|
None
|
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_VAL
|
EU of TRK_SCALE
|
The input value with status applied to OUT in LO mode.
