Description
Selects timing execution mode.
0 = Periodic 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
Execution time for oversample mode.
Valid = 0 to 4194.303 seconds
Default = 0
Module update period for real time sampling mode
Valid = 1 to 32,767ms
Default = 1
Module time stamp value for real time sampling mode.
Valid = 0 to 32,767ms
Default = 0
Description
Indicates if instruction is enabled. Cleared to false if Out overflows.
The calculated output of the algorithm.
The maximum limit alarm indicator. Set when the calculated value for Out
HighLimit and the output is clamped at HighLimit.
The minimum limit alarm indicator. Set when the calculated value for Out
LowLimit and the output is clamped at LowLimit.
Elapsed time between updates. This is the elapsed time in seconds used by
the control algorithm to calculate the process output.
Status of the function block.
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.
Gain < minimum positive float.
WLag > maximum or WLag < minimum.
WLead > maximum or WLead < minimum.
ZetaLead > maximum or ZetaLead < minimum.
HighLimit LowLimit.
Invalid timing mode.
For more information about timing modes, see Function Block Attributes.
Only used in real time sampling mode. Set when ABS | DeltaT - RTSTime | > 1
(.001 second).
