8.8 Use of Two Final Storage Areas – Saving Data
Prior to Event
One of the uses of two Final Storage Areas is to save a fixed amount of data be-
fore and after some event.
In this example, the output of a load cell is measured every second. It is assumed
that at some random interval the load will exceed 11.4kg for less than 10 seconds.
Exceeding 11.4kg is the event to be captured. The data from the 10 seconds
before the event and 10 seconds after the event is to be saved (21 seconds
including the scan in which the load first exceeds 11.4kg).
Every second the output of the load cell is measured; hours-minutes, seconds and
the load are output to Final Storage Area 2 (four values with the Array ID).
