When using the sample trigger module in DASYLab what are the differences between Threshold Value exceeded and Greater than threshold? Also what is the difference between threshold value undershot and smaller than threshold?

Threshold value exceeded and Threshold value undershot both require movement of the data with an automatic hysteresis.

To evaluate as true, the value must start below the Threshold Value exceeded parameter, and rise above it. It cannot evaluate as true again until the value has fallen below the threshold. It will trigger only once per threshold event.

The same for the Threshold value undershot - the value must start above the threshold value, and drop below it. It cannot retrigger until the value has risen above the threshold.

Greather than and Smaller than threshold are absolute triggers... it will evaluate as true for each value that is greater than or smaller than the threshold value. It will re-trigger constantly, until the value is below or above the threshold.
