Diagram Tab

  • Power table: Apparent Power, Active Power and Reactive Power of Grid, Load, Pv, Gen and Battery Converter
  • Storage DC card: storage DC power and SoC
  • Diagram menu: the three-dot icon at the top left of the diagram. Items: Edit, Add device.
  • Save icon: top right of the diagram. Saves the device positions.
  • Edit mode tag: shown on the diagram when Edit is on

The diagram has no zoom control. It changes its size to fit the window.

Diagram Interaction

The diagram has two modes. Edit in the diagram menu changes between them.

View mode:

  • Click on a device: opens the Data window, with live values and setpoints
  • Pointer on a line: highlights all the lines of its AC loop
  • Drag on a touch screen: scrolls the page

Edit mode:

  • Drag a device: moves the device. Click the save icon to keep the new position.
  • Drag from dot to dot: adds a line between two devices. See Add and connect devices in plant control.
  • Pointer on a line: shows a red X. Click the X to remove the line.
  • Double-click on a device: opens the Settings window of the device

Examine a setting before you save it. Plant Control applies a saved setting to live equipment, with no confirmation step.

Device Menu

The three-dot icon on the Plant Control System card, above the tabs, opens these panels:

  • Ctrl Chart: control history chart
  • Control Health: read and write timing of each controlled device
  • PID Tuning: control loop tracking and gains
  • System ID: open-loop bump test
  • AC Loop Overview: grid power against target for each AC loop
  • LOMAC: LOMAC status and timeline. See Set up and arm LOMAC.

Do not start a System ID test on a site in operation without approval from the site owner. The test takes control of the device and changes its power output.
