RatioLimitsInv
(Status1.11)
BOOL RatioLLimit < 0 or RatioHLimit < RatioLLimit.
CVProgInv
(Status1.12)
BOOL CVProg < 0 or CVProg > 100, or CVProg < CVLLimit or CVProg > CVHLimit
when CVManLimiting is true. The instruction limits the value for CV.
CVOperInv
(Status1.13)
BOOL CVOper < 0 or CVOper > 100, or CVOper < CVLLimit or CVOper > CVHLimit
when CVManLimiting is true. The instruction limits the value for CV.
CVOverrideInv (Status1.14) BOOL CVOverride < 0 or CVOverride > 100. The instruction limits the value for CV.
CVPreviousInv (Status1.15) BOOL CVPrevious < 0 or CVPrevious > 100, or CVPrevious < CVLLimit or CVPrevious >
CVHLimit when in Auto or Cascade/Ratio mode. The instruction limits the value
of CVn-1.
CVEUSpanInv
(Status1.16)
BOOL Invalid CVEU span. The instruction uses a value of
CVEUMax = CVEUMin.
CVLimitsInv
(Status1.17)
BOOL CVLLimit < 0, CVHLimit > 100, or CVHLimit < CVLLimit. If CVHLimit <
CVLLimit, the instruction limits CV using CVLLimit.
CVROCLimitInv
(Status1.18)
BOOL CVROCLimit < 0. The instruction disables ROC limiting.
FFInv (Status1.19) BOOL FF < -100 or FF > 100. The instruction uses the limited value for FF.
FFPreviousInv
(Status1.20)
BOOL FFPrevious < - 100 or FFPrevious > 100. The instruction uses the limited value
for FF
n-1.
HandFBInv
(Status1.21)
BOOL HandFB < 0 or HandFB > 100. The instruction uses the limited value for CV.
PGainInv
(Status1.22)
BOOL PGain < 0. The instruction uses a value of PGain = 0.
IGainInv
(Status1.23)
BOOL IGain < 0. The instruction uses a value of IGain = 0.
DGainInv
(Status1.24)
BOOL DGain < 0. The instruction uses a value of DGain = 0.
ZCDeadbandInv
(Status1.25)
BOOL ZCDeadband < 0. The instruction disables zero crossing deadband.
PVDeadbandInv
(Status1.26)
BOOL PVDeadband < 0. The instruction limits PVDeadband to zero.
PVROCLimitsInv
(Status1.27)
BOOL PVROCPosLimit < 0, PVROCNegLimit < 0, or PVROCPeriod < 0.
DevHLLimitsInv
(Status1.28)
BOOL Deviation high-low limits invalid. Low-low limit < 0,
low limit < 0, high limit < 0, or high-high limit < 0. The instruction uses 0 for
the invalid limit.
DevDeadbandInv
(Status1.29)
BOOL Deviation deadband < 0. The instruction uses a value of DevDeadband = 0.
Status2 DINT Timing status of the function block.
TimingModeInv
(Status2.27)
BOOL Invalid TimingMode value.
For more information about timing modes, see Function Block Attributes.
RTSMissed
(Status2.28)
BOOL Only used in real time sampling mode. Set to true when
ABS | DeltaT - RTSTime | > 1 (.001 second).
RTSTimeInv
(Status2.29)
BOOL Invalid RTSTime value.
RTSTimeStampInv
(Status2.30)
BOOL Invalid RTSTimeStamp value.
DeltaTInv
(Status2.31)
BOOL Invalid DeltaT value.
