The logging rate entry tells the DXN how often to collect data points. The logger memory area has the capacity to store more
than 300 individual files consisting of a maximum of 65,500 points per log file.
The amount of time the logger will collect data depends on the Logging Rate the DXN is programmed for. In general the
logging time is calculated by dividing 65,563 by the number of data points recorded per minute.
