Equipment, devices, and gateways

Equipment

Equipment in Energy Hub represents a real-world piece of equipment that is part of the electrical infrastructure of your facility. Equipment can be connected or non-connected. Connected equipment has communication capabilities and can be accessed directly by Energy Hub to retrieve information.

Examples of equipment include transformers, switchgear, breakers, uninterruptible power sources, motors, and motor drives.

Panelboards

A panelboard in Energy Hub represents a real-world electrical enclosure in your facility that divides a power feed into circuits with protective fuses and circuit breakers.

Energy Hub automatically creates panelboards when you add a new gateway, such as Site Server, based on the device configuration of the gateway. You can also create panelboards manually.

Panelboards have linked devices that monitor the supply and load circuits of the panelboard. You can manually link devices or rearrange devices that have been linked automatically. For Energy Hub to interpret the measurement data for a panelboard correctly, you need to assign the context for the linked devices as either main (incoming) devices or feeder (outgoing) devices.

Devices

A device in Energy Hub represents a real-world monitoring device that provides measurement data for the loads and energy supplies in your facility. Devices can be discrete, such as power meters, or they can be integrated into equipment. For a list of supported devices in Energy Hub, see Supported gateways and devices list.

Virtual Devices

In Energy Hub, a virtual device is a software component that can monitor the unmetered load for a panelboard.

Unmetered load is the difference between the incoming energy and the metered outgoing energy for a panelboard (mains – feeders). You can add one or more virtual devices to a panelboard and allocate a percentage of the unmetered load to them. To identify the type of load that is represented by a virtual device, you assign an energy usage type to the device. The workflow for assigning an energy usage type to a virtual device is the same as for a physical device. For example, you could assign a usage type of Lighting (interior) to a virtual device to represent an unmetered lighting load.

Virtual devices provide energy and demand but no voltage, current, status, or other measurements.

NOTE: For Energy Hub to identify the unmetered load for a panelboard correctly, all incoming supplies to the panel must be monitored and must be assigned as main (incoming) devices for the panelboard in Energy Hub.

Gateways

A gateway connects equipment and monitoring devices in your facility to Energy Hub.

A gateway is a communication device that pushes measurement data from monitoring devices to Energy Hub. Gateways are installed locally in your facility. They have access to monitoring devices through device communication networks, and access to the Energy Hub through internet connected IT networks. For a list of supported gateways in Energy Hub, see Supported gateways and devices list.

Notes on importing device data and information from a gateway into Energy Hub:

Configuration information

Device information, such as device name and energy usage types, that is configured on the gateway, is imported into Energy Hub when the gateway is first added to Energy Hub. Any changes to this information on the gateway after it has been added will not be updated in Energy Hub. When a new monitoring device is added to a gateway that is connected to Energy Hub, the new device information is imported into Energy Hub. Any later changes to this device information on the gateway are not updated in Energy Hub. When a device is removed from a gateway that is connected to Energy Hub, the device will not be deleted in Energy Hub. This is because Energy Hubwill have historical data stored for the device. No configuration information is pushed from Energy Hub to the gateway.

Historical energy system data

When a gateway is connected to Energy Hub, it automatically starts uploading historical data on a regular basis. For pre-existing data that was recorded by the gateway before it was connected, up to one month (PAS600) or three months (PAS800) of that data is uploaded to Energy Hub.

NOTE: The upload of pre-existing historical data is available for Panel Servers with firmware version 1.9 and greater. For older versions, no pre-existing historical data is uploaded from the gateway when it is connected to Energy Hub.
