TimingMode DINT Selects timing execution mode.
0 = Periodic mode
1 = Oversample mode
2 = Real time sampling mode
Valid = 0 to 2
Default = 0
RTSTimeStamp DINT Module time stamp value for real time sampling mode.
Valid = 0 to 32,767ms
Default = 0
Output Parameter Data Type Description
EnableOut BOOL Indicates if instruction is enabled.
Cleared to false if Out overflows.
Out REAL The calculated output of the
algorithm.
DeltaT REAL Elapsed time between updates.
This is the elapsed time in seconds
used by the control algorithm to
calculate the process output.
Status DINT Status of the function block.
InstructFault (Status.0) BOOL The instruction detected one of the
following execution errors. This is
not a minor or major controller
error. Check the remaining status
bits to determine what occurred.
WLeadInv (Status.1) BOOL WLead < minimum value or
WLead > maximum value.
WLagInv (Status.2) BOOL WLag < minimum value or WLag
> maximum value.
ZetaLeadInv (Status.3) BOOL Lead damping factor < minimum
value or lead damping factor >
maximum value.
ZetaLagInv (Status.4) BOOL Lag damping factor < minimum
value or lag damping factor >
maximum value.
OrderInv (Status.5) BOOL Invalid Order value.
WLagRatioInv (Status.6) BOOL WLag:WLead ratio greater than
maximum value.
TimingModeInv (Status.27) BOOL Invalid TimingMode value.
For more information about timing
modes, see Function Block
Attributes.
RTSMissed (Status.28) BOOL Only used in real time sampling
mode. Set when
ABS (DeltaT - RTSTime) > 1
millisecond.
RTSTimeInv (Status.29) BOOL Invalid RTSTime value.
RTSTimeStampInv (Status.30) BOOL Invalid RTSTimeStamp value.
DeltaTInv (Status.31) BOOL Invalid DeltaT value.
