Process Control Instructions
Rockwell Automation Publication 1756-RM006K-EN-P - November 2018 141
TimingMode DINT Selects timing execution mode.
0 = Period mode
1 = Oversample mode
2 = Real time sampling mode
For more information about timing modes, see
Function Block Attributes.
Valid = 0 to 2
Default = 0
OversampleDT REAL Execution time for oversample mode.
Valid = 0 to 4194.303 seconds
Default = 0
RTSTime DINT Module update period for real time sampling
mode
Valid = 1 to 32,767ms
Default = 1
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 Total overflows.
Total REAL The totalized value if In.
OldTotal REAL The value of the total before a reset occurred.
You can monitor this value to read the exact
total just before the last reset.
ProgOper BOOL Program/operator control indicator. True when
in Program control. False when in Operator
control.
RunStop BOOL The indicator of the operational state of the
totalizer. True when the TOT instruction is
running. False when the TOT instruction is
stopped.
ProgResetDone BOOL The indicator that the TOT instruction has
completed a program reset request. Set to true
when the instruction resets as a result of
ProgResetReq. You can monitor this to
determine that a reset successfully completed.
Cleared to false when ProgResetReq is false.
TargetFlag BOOL The flag for Total. Set to true when Total
Target.
TargetDev1Flag BOOL The flag for TargetDev1. Set to true when Total
Target - TargetDev1.
TargetDev2Flag BOOL The flag for TargetDev2. Set to true when Total
Target - TargetDev2.
LowInCutoffFlag BOOL The instruction low input cutoff flag output. Set
to true when
In £ LowInCutoff.
DeltaT REAL Elapsed time between updates. This is the
elapsed time in seconds used by the control
algorithm to calculate the process output.
