The idea was to acquire data as fast as reliable and store data in a revolving buffer. Data would be stored and moved into a permanent location for an x amount of time before and after the quench event signal. Normal operation would store or write data at ~1sec interval to the standard historian/archive data stream.<br><br>The algorithm to handle the revolving temporary data stream until an event triggers storing it has not been worked out.<br><br>Thanks<br>Steven<br></div></body></html>
