The task of building charts for I/O channel values comprises two steps:

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.
