View or control mode

When you open a schematic, it initially appears in the view mode. In this mode, you can view the screen or (depending on your authorization) control it, that is, write to individual data points.

You can learn about editing schematics in the section Edit mode.

Faceplate: Control the schematic

When you click on a shape in view mode, its faceplate appears. On it, you can view or control the current live values of the underlying data points.


The faceplate of the shape “Pump”

The values of certain properties can be changed and written on the faceplate. The changes are saved immediately. If you made changes and closed the faceplate, you will also be prompted to enter an (optional) comment on the changes made.

The following table explains the different symbols on the faceplate.

Add to chart

Displays the history of measurements of this data point in a temporary chart.

Alarm status

The data point is currently set to alarm.

Show Priority Array

Displays the priority array with all current values. The symbol to its left depicts the status of the present value, depending on how the priority array was configured. More information on how to configure the priority array can be found in Configure priority array.

The present value was written automatically by the automation (PLC).

The present value was set via the Avelon control system and overrides the automation.

The present value was set on site or with a priority higher than the control system and overrides the automation.

The present value was set either by a manual emergency switch on site or by the automation to ensure the protection of the system and the safety of the operators.

The present value was set either by a manual emergency switch on site or by the automation to ensure the protection of the system and the safety of the operators. At the same time, the value was also set via the Avelon control system. The former will always take precedence.

(icon missing)

Based on the current configuration of the priority array, it is not possible to determine a specific state. It is advised to adapt the configuration of the priority array for that Beetle (see reference above).

If the present value was written with the priority preset by the Avelon control system (8 by default), the value can be reset by clicking on Reset. This is possible directly on the faceplate as long as the value is not currently overridden with an even higher priority. Otherwise, the value can be reset using the same symbol in the dialog Priority Array mentioned above.

Put out of service

Sets the “Out of Service” flag of the object to True.

Put into service

Sets the “Out of Service” flag of the object to False.

Alarm Tickets

Using this menu, all alarms related to the data points placed on this shape can be either acknowledged or resolved.


Information displayed on the faceplate is always read directly from the device. In contrast, the information used to animate the shape is usually loaded from the local cache. If you notice differences between the representation of a shape and the information on its faceplate, you should synchronize the data point concerned with the Avelon control system again (see Reconcile BACnet objects or Reconcile OPC UA nodes).


If you click on Add to Chart on the faceplate described above, the measurements of the respective data point are displayed in a temporary chart. You can show or hide this chart at any time using the Chart tab at the bottom of the screen.

Up to 10 different measured data points can be displayed simultaneously in this measurement chart. If you want to display additional series of measurements, you must remove others. However, a maximum of 3000 measurement values can be displayed per data point. For advanced analysis options, please use the chart widgets (see Charts).

You can convert the plots of the temporary chart into a regular chart widget. This will not only allow you to preserve the chart independently of the schematic, but you will also be able to customize it or use it in reports. To convert the chart, click on More in the top right corner of the chart and click on Convert to Widget. The new chart widget will be placed on the same dashboard as the schematic widget.


Clicking on the Tickets tab shows a list of all tickets associated with the schematic or the current system. The list behaves similarly to the ticket list widget. The handling of tickets is described in detail in the chapter Ticket list.


Documents such as data sheets, operating instructions or checklists can be attached to each shape placed on the schematic. These can be displayed and downloaded via the Documents button from the faceplate. The icon will be displayed at the bottom left of the faceplate if there are documents attached to the shape. For more information on how to manage these documents, see section Manage documents.

QR code

You can generate a QR code that you can scan with your mobile device to directly open the current schematic.

To do so, click on More at the top right and then on Download (make sure you’re actually on the fullscreen view of the schematic, not on the dashboard). In the following dialog, either click Download or Print under QR Code to download or print the QR code respectively.

The QR code will be placed on a document measuring 102 × 64 mm, which can be printed on a thermal transfer label for increased durability with a suitable printer (e.g. Zebra), or on regular paper with any printer.
