RatioLLimit < 0 or RatioHLimit < RatioLLimit.
CVProg < 0 or CVProg > 100, or CVProg < CVLLimit or CVProg > CVHLimit
when CVManLimiting is true. The instruction limits the value for CV.
CVOper < 0 or CVOper > 100, or CVOper < CVLLimit or CVOper > CVHLimit
when CVManLimiting is true. The instruction limits the value for CV.
CVOverride < 0 or CVOverride > 100. The instruction limits the value for CV.
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.
Invalid CVEU span. The instruction uses a value of
CVEUMax = CVEUMin.
CVLLimit < 0, CVHLimit > 100, or CVHLimit < CVLLimit. If CVHLimit <
CVLLimit, the instruction limits CV using CVLLimit.
CVROCLimit < 0. The instruction disables ROC limiting.
FF < -100 or FF > 100. The instruction uses the limited value for FF.
FFPrevious < - 100 or FFPrevious > 100. The instruction uses the limited value
for FF
n-1.
HandFB < 0 or HandFB > 100. The instruction uses the limited value for CV.
PGain < 0. The instruction uses a value of PGain = 0.
IGain < 0. The instruction uses a value of IGain = 0.
DGain < 0. The instruction uses a value of DGain = 0.
ZCDeadband < 0. The instruction disables zero crossing deadband.
PVDeadband < 0. The instruction limits PVDeadband to zero.
PVROCPosLimit < 0, PVROCNegLimit < 0, or PVROCPeriod < 0.
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.
Deviation deadband < 0. The instruction uses a value of DevDeadband = 0.
Timing status of the function block.
Invalid TimingMode value.
For more information about timing modes, see Function Block Attributes.
Only used in real time sampling mode. Set to true when
ABS | DeltaT - RTSTime | > 1 (.001 second).
Invalid RTSTime value.
Invalid RTSTimeStamp value.
Invalid DeltaT value.
