Output Parameters
Output Parameter Data Type Description
DeltaT REAL Elapsed time between updates. This is the elapsed time in seconds used by the control algorithm to
calculate the process output.
Periodic: DeltaT = task scan rate if task is Periodic task, DeltaT = elapsed time since previous
instruction execution if task is Event or Continuous task
Oversample: DeltaT = OversampleDT
Real Time Sampling: DeltaT = (RTSTimeStamp
n
- RTSTimeStamp
n-1
)
Status DINT Status of the function block.
TimingModeInv
(Status.27)
BOOL Invalid TimingMode value.
RTSMissed (Status.28) BOOL Only used in real time sampling mode. Set when ABS | DeltaT - RTSTime | > 1 (.001 second).
RTSTimeInv (Status.29) BOOL Invalid RTSTime value.
RTSTimeStampInv
(Status.30)
BOOL Invalid RTSTimeStamp value.
DeltaTInv (Status.31) BOOL Invalid DeltaT value.
