1. From the Device tab, click . The system opens a guided configuration process to define the new device.

2. Configuration steps:

   2.1. Define Device and Electrical Characteristics, by filling the following fields,

   Element	Description
   Select protocol	Select the protocol: Modbus TCP Modbus RTU P1 Virtual (see Virtual device)
   Select device	Chose a device that is connected
   Device name	Define the device name that appears in the card

   2.2. Define System Type and Number of Loads*,

   2.3. Activate/deactivate each single load and assign a label name*

   *Note: the available parameters depend on the selected model and protocol.

3. Click Save .

After saving, the Web App automatically opens the Product overview page that summarizes the device’s characteristics and current status.

Each device is represented by a card showing an icon and the device name. Cards allow:

• Access device panoramic by clicking on the card or on , the user is redirected to the Product overview page

• Edit device features by clicking on and selecting , the user is redirected to the procedure described in Add a new device.

• Delete the device, by clicking on and selecting .

  *Note: user accessibility to this function is managed by the type of user permissions.

The Product Overview page provides a graphical summary of the selected device. It displays general device information, real-time variables, diagnostic messages, and configuration parameters. The layout is composed of two main cards and a navigation menu at the top of the page.

Area	Element	Description
A	Device Information Card	This fixed card displays general information about the device, such as name, model, communication type, and connection status. By clicking on and selecting , the user can edit the device feature, being redirected to the procedure described in Add a new device.
B	Dynamic Data Card	This card changes content depending on the selected menu tab (see below) By clicking on , user can send reset commands, described in the table below: Command Description Total reset It resets the total energy meters and the total run hour counters Partial reset It resets the partial energy meters and the partial run hour counters Reset tariff It resets the tariff settings to the default
C	Navigation tabs	At the top of the page, a horizontal menu allows switching between different tabs: Overview, a series of Variables groups, Diagnostics , and Settings . Selecting a tab updates the content of the dynamic data card accordingly.

Note: the available information and commands on the cards depend on the selected model and the user permission.

The Virtual Device is a special type of device that does not correspond to a physical instrument. Instead, it represents an aggregation of data obtained from one or more physical loads. Each Virtual Device includes its own virtual load, whose signals are calculated as the result of additions or subtractions between homogeneous variables from selected physical devices.

 

Purpose

Virtual Devices are used to:

• Create cost centers, by summing the power or energy values of multiple loads.

• Build consumption profiles, by subtracting consumed energy from produced energy.

• Monitor current levels and detect overloads, by aggregating currents on the same phase.

Add a virtual device

1. From the Device tab, click . The system opens a guided configuration process to define the new device.

2. Select Virtual Device field Select protocol.

3. Follow the configuration wizard selecting the load and defining the operation choice (adding or subtracting loads data).
   To select the operation between loads, click the operation icon: by default it shows the , symbol for addition; clicking it switches the icon to , symbol for subtraction.
   

   Note: A maximum of five physical loads can be grouped into a single Virtual Device.

4. Click Save .

Default values can later be enabled or disabled through checkboxes, as described in the standard editing process (see Add a new device).

Interaction and Management

The Virtual Device uses the same data sampling rate as the physical devices. It can be used exactly like a real device — its data can be displayed in graphs, reports, and can also be mapped in Modbus or BACnet gateways.

Once created, a Virtual Device appears in the Devices section and can be managed like any other device. The user can:

• View real-time aggregated data in the Product Overview (see Product overview page);

• Modify its configuration (add, remove, or change loads, and adjust operations between them);

• Enable/disable selected signals;

• Delete the Virtual Device when it is no longer needed.

It is not possible to delete a physical device if one of its loads is used in a Virtual Device; the application will notify the user of the dependency.

Notes:

• When aggregating signals from single-phase devices, EMS automatically interprets them as system-level variables.

• Real-time data of a Virtual Device update automatically whenever one of the related physical signals changes.

• If one of the contributing signals becomes invalid, the corresponding aggregated signal is marked as invalid as well.
