Status3CV3 DINT Additional bit mapped CV3 status for
the function block. A value of 0
indicates that no faults have
occurred.
InstructFault BOOL The function block has generated a
fault. Indicates state of bits in
Status1, Status2, and Status3CV(n),
where (n) can be 1, 2, or 3.
A value of 0 indicates that no faults
have occurred. Any parameters that
could be configured with an invalid
value must have a status parameter
to indicate their invalid status.
PVFaulted BOOL Process variable PV health bad.
PVSpanInv BOOL The span of PV inValid, PVEUMax <
PVEUMin.
SPProgInv BOOL SPProg < SPLLimit or > SPHLimit.
Limit value used for SP.
SPOperInv BOOL SPOper < SPLLimit or > SPHLimit.
Limit value used for SP.
SPLimitsInv BOOL Limits inValid: SPLLimit < PVEUMin,
SPHLimit > PVEUMax, or SPHLimit
< SPLLimit. If SPHLimit < SPLLimit,
then limit value by using SPLLimit.
SampleTimeTooSmall BOOL Model DeadTime / DeltaT must be
less than or equal to 200.
FactorInv BOOL Entered value for Factor < 0.
TimingModeInv BOOL Entered TimingMode inValid. If the
current mode is not Override or Hand
then set to Manual mode.
RTSMissed BOOL Only used when in Real Time
Sampling mode. Is TRUE when
ABS(DeltaT – RTSTime) > 1
millisecond.
RTSTimeInv BOOL Entered RTSTime inValid.
RTSTimeStampInv BOOL RTSTimeStamp inValid. If the current
mode is not Override or Hand, then
set to Manual mode.
DeltaTInv BOOL DeltaT inValid. If the current mode is
not Override or Hand then, set to
Manual mode.
CV1Faulted BOOL Control variable CV1 health bad.
CV2Faulted BOOL Control variable CV2 health bad.
CV3Faulted BOOL Control variable CV3 health bad.
CV1HandFBFaulted BOOL CV1 HandFB value health bad.
CV2HandFBFaulted BOOL CV2 HandFB value health bad.
CV3HandFBFaulted BOOL CV3 HandFB value health bad.
CV1ProgInv BOOL CV1Prog < 0 or > 100, or <
CV1LLimit or > CV1HLimit when
CVManLimiting is TRUE. Limit value
used for CV1.
