Most applications work by acquiring and calculating data at regular intervals, defined in seconds, minutes, or hours. iFIX can perform any combination of time-based processing. This allows you to balance system resources between data that needs to be acquired quickly and data that can be acquired over longer intervals.
SAC can perform time-based processing in:
- Subseconds (0.05 seconds to 0.95 seconds)
- Seconds
- Minutes
- Hours
The frequency with which SAC retrieves data is called the scan time. For more information on scan times, refer to the Building a SCADA System manual.
