Iotellect SCADA/HMI provides several ways to view and analyze I/O channel values over time.

The Analytics Console can be used for quick analysis of real-time and historical values. For HMI visualization, charts can be added to dashboards as dashboard components.

If historical values should be displayed, channel history storage must be enabled for the corresponding device variables.

Analytics Console

The Analytics Console is used to view and analyze time-based data, such as I/O channel values, device variables, and historical trends.

The console includes two chart modes:

Regular Chart — displays selected values over a specified time range. It can be used to view recent or historical values and may include real-time data.

Aggregated Chart — displays aggregated values for the selected time range. The aggregation period and aggregation function can be configured, for example to calculate average values over hourly or daily intervals.

Historical values shown in charts depend on device variable history settings.

Enabling Channel History Storage

By default, any I/O channel in Iotellect SCADA/HMI doesn't store its historical values. To enable history storage:

  • Right-click on a device account () in the System Tree.

  • Select Edit Device Properties ().

  • Switch to Device Settings Synchronization Options () tab and set necessary storage time for one or more properties.

  • Click OK to save the settings.

For more information on the above settings, see Device Settings Synchronization Options.

Building Chart Dashboard

In Iotellect SCADA/HMI, charts are dashboard components. See Charts section for comprehensive description of chart data model, properties, and use cases. Creating a chart for displaying historical and real-time channel values can be done by following the tutorial monitoring device parameters using a chart.
