Using the logging wizard for data logging of flow
measurements
The Logging Wizard is the easiest way to set-up the data logging feature after the main
application is set-up.
As an example, consider data logging of the control unit PV value (D800) every 15
minutes; the control unit PV is a flow measurement in cubic meters per second. When the
flow measurement is at 1 cubic meter per second or more, the Fast Log mode is required
to activate. When the memory is at 90% of capacity, a relay is activated instead of
overwriting old data.
