Explanation
DisplayDataandEventData
There are two file types: display data and event data.
Display data can be likened to the conventional recording on the chart sheet and are useful
for long-term recording.
In the case of display data, the GX/GP records the maximum and minimum values from the
measured values within each recording interval (Instantaneous data in each scan interval).
Event data is useful when you wish to record the measured data in detail.
In the case of event data, the GX/GP records the measured values at every recording
interval (Instantaneous data in each scan interval).
