Profile takes readings from the RTU at a regular interval and records the readings in its own internal database. Profile keeps all stored data indefinitely.
The historical data interval is set by the system administrator and can be anywhere between 1 hour and 1 day.
Fields that are being recorded will be displayed on the chart. The legend for the chart is shown next to the fields.
The chart on the Process Data page defaults to showing the last 24 hours.
If none of the fields on the screen have historical data, then the chart will not be shown.
