On Scan |
|

Data Collected |
At a regular interval. The interval equals the base scan rate for the port on which the device is located multiplied by the scan rate for the point. |
|
Value Updated |
The point's value is updated at the point's scan interval, whether or not the value changes. Because this can increase system load, it is recommended that you use On Scan sparingly or not at all. |
