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.
HighAlarm BOOL High limit alarm indicator. When Out
HighLimit, HighAlarm is set and the output is
limited to the value of HighLimit.
LowAlarm BOOL Low limit alarm indicator. When Out
LowLimit, LowAlarm is set and the output is
limited to the value of LowLimit.
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.
IGainInv (Status.1) BOOL IGain > maximum or IGain < minimum.
HighLowLimsInv (Status.2) BOOL HighLimit LowLimit.
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 (.001 second).
RTSTimeInv (Status.29) BOOL Invalid RTSTime value.
RTSTimeStampInv (Status.30) BOOL Invalid RTSTimeStamp value.
DeltaTInv (Status.31) BOOL Invalid DeltaT value.
