AtuneCVLimitsFau
lt
BOOL CVLimitsInv and CVManLimiting are True at
start of Autotuning or during Autotuning.
When True, Autotuning is not started or is
aborted.
Bit 5 of
AtuneStatus
AtuneCVInitFault BOOL CVInitializing is True at start of Autotuning
or during Autotuning. When True,
Autotuning is not started or is aborted.
Bit 6 of
AtuneStatus
AtuneEUSpanChan
ged
BOOL CVEUSpan or PVEUSpan changes during
Autotuning. When True, Autotuning is
aborted.
Bit 7 of
AtuneStatus
AtuneCVChanged BOOL CVOper is changed when in Operatior
control or CVProg is changed when in
Program control or CV becomes high/low
or ROC limited during Autotuning. When
True, Autotuning is
aborted.
Bit 8 of
AtuneStatus
AtuneTimeout BOOL Elapsed time is greater then
AtuneTimeLimit since step test is started.
When True, Autotuning is aborted.
Bit 9 of
AtuneStatus
AtunePVNotSettle
d
BOOL The PV is changed too much to Autotune.
When True, Autotuning is aborted. Wait
until PV is more stable before autotuning.
Bit 10 of
AtuneStatus
Status1 DINT Bit mapped status of the function block.
Status2 DINT Additional bit mapped status for the
function block.
InstructFault BOOL Function block has generated a fault.
Indicates state of bits in Status1 and
status2.
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.
Bit 0 of Status1
PVFaulted BOOL Process variable PV health bad. Bit 1 of Status1
CVFaulted BOOL Control variable CV faulted Bit 2 of Status1
HandFBFaulted BOOL HandFB value health bad Bit 3 of Status1
PVSpanInv BOOL The span of PV invalid, PVEUMax <
PVEUMin.
Bit 4 of Status1
SPProgInv BOOL SPProg < SPLLimit or > SPHLimit. Limit
value used for SP.
Bit 5 of Status1
SPOperInv BOOL SPOper < SPLLimit or > SPHLimit. Limit
value used for SP.
Bit 6 of Status1
SPCascadeInv BOOL SPCascade < SPLLimit or > SPHLimit. Limit
value used for SP.
Bit 7 of Status1
SPLimitsInv BOOL Limits invalid: SPLLimit < PVEUMin,
SPHLimit > PVEUMax, or SPHLimit <
SPLLimit. If SPHLimit < SPLLimit, then
limit value using SPLLimit.
Bit 8 of Status1
RatioLimitsInv BOOL Ratio high-low limits invalid, low limit < 0
or high limit < low limit.
Bit 9 of Status1
RatioProgInv BOOL RatioProg < RatioLLimit or > RatioHLimit.
Limit value used for Ratio.
Bit 10 of Status1
