Energy Management Controller VMU-CThe VMU-C Energy management controller is the ideal web-server based solution for monitoring small to medium size installations. Gathering data from energy meters, power analysers and VMU series I/O modules (refer below), the VMU-C provides an easy to use monitoring system assisting organisations to optimise their energy and resource consumption and achieve good industry efficiency ratings such as NABERS and Green Star.

With its integrated machine to machine (M2M) functionalities it is capable of automatically transferring data via FTP, HTTP or MODBUS/TCP to a remote server where a SCADA, BMS or other specific database software is running.

By combining VMU-C with VMU-Y or EM2-Server, the end user has the ability to remotely manage multi-site installations (more detail on the following pages).

An integrated Wired Web-Server Solution Since plant data is very important, VMU-C dedicates 4 GB of memory to secure data storage. VMU-C provides also a micro SD slot (up to 32 GB SDHC cards) and a hot-swap USB interface (for direct memory stick connection) on the top of the unit for:

• Plant configuration backup and restore;

• Plant database backup and restore

The Ethernet interface allows to operate and configure the VMU-C, by means of LAN or direct connection to a PC, thanks to the integrated web-interface. In the case Ethernet cannot be accessed, the mini USB can be connected to a PC .

Advantages of the VMU-C Onsite Database• No need for a dedicated PC for monitoring

• No crash problems which lead to data loss

• No compatibility problems due to different operating systems, different languages, libraries, etc

• Polling device, datalogger, Ethernet gateway all available in a single compact unit

• Modular concept for additional input/output whenever needed

VMU Series Optional ModulesAdditional signalling modules can be added easily and quickly to the VMU-C control unit, either connected directly to the local bus or remotely connected via the VMU-M master unit.

Application examples of where these modules are best suited include:• Remote signalling when event or alarm is triggered on the VMU-C control unit• Temperature and other analogue measurements• Event/Alarm signalling to the VMU-C• General speed/flow measurements

1) VMU-P does not count pulses. Pulse aggregator D4CR12 or meter with pulse aggregator function such as EM24DIN should be used if required2) VMU-M connects to RS485 port COM1 should be used if required

Examples of Embedded Webserver DashboardsBy simply opening your internet browser and logging into your VMU-C via the IP address, a number of pages are available to analyse and monitor the information recorded.

The home page provides a dashboard containing:

• Energy consumption information (active and reactive power and energy);

• Cost information (yearly, monthly and daily expenses);

• Instantaneous 3-phase variables of the plant (voltages and currents);

• Graph comparing present day to previous days total energy consumption

Refer below image for example

From the home screen, the user can easily navigate to other pages including:

• Monitor page: Displays instantaneous variables on a daily, monthly or annual basis. The variables can be monitored by specific set points. In the case of problems or faults, it is possible to analyse the plant’s history before the event, so as to understand the relevant reasons and act accordingly.

• Plant page: All the real-time variables of any meter can be displayed in this section. This is very useful for confirming meter operation and fault diagnosis.

• Economy page: The consumption of each energy meter can be analysed on a daily, monthly or annual basis. In the same section information acquired by pulses from the gas, water or remote heating meters, and also the analogue and environmental variables acquired by the VMU modules, can be displayed and analysed.

• Export page: The database, including all the history of the plant, can be accessed to get a set of data in a defined time period. The data is then available in Excel compatible format for further analysis by the user.

Scalable Multi-site Energy Management Solutions A single centralised energy management database is possible with the VMU-Y or EM²-Server options available from NHP.

Ideal for applications involving monitoring many different zones and different site locations, information recorded by the multiple VMU-C control units is easily accessible by users from any location simply by using a standard web-browser.

More comprehensive data exporting is available from both the VMU-Y and EM²-Server packages with any variable from any connected meter exportable

Embedded Solution VMU-YThe VMU-Y can connect to 10x VMU-C control units collating all the information to one centralised database.

The VMU-Y is embedded within a compact 2-DIN module hardware similar in appearance to the VMU-C control unit, providing a comprehensive multi-site energy management database. There is no need to install any software, with quick and easy connection to the VMU-C control units.

Examples of VMU-Y dashboards are described on the folowing page.

Examples of VMU-Y and EM2-Server DashboardsMultiple Screen, Multiple Views

Em2-Server’s web interface allow users to match the needs of control rooms, by allowing the simultaneous displaying of different charts and information on the same monitor of on same screens.

Position and size of the desired displaying tools can be saved for later use.

Multi-site Information Management

By using the Map and Navigator tools it is possible to locate information from distributed installations with ease, according to user’s access rights.

Present or historical values and charts are displayed according to the selected parameters and filters.

Devices ‘Status and Installations’ Alerts Monitoring

Dedicated tools allow users to immediately check if any abnormal situation or unexpected condition is affecting the monitored plants and the monitoring devices.

Distributed VMU-C EM units can be surfed via VPN and commands may be broadcasted to pools of units.

Tariff Profiling

Multiple tariffs may be set, splitting days in hourly slices, and defining calendars based on different daily profiles according to company needs: monthly cost reports are available as XLS files based tarrifs and real consumption data.

Synoptics (only available on EM2 Server)

It is possible to create synoptic views as combinations of maps, diagrams, schematics and live icons representing the desired meters.

Load Profiling

The load profile tool allow statistical calculation of consumption in the single demand interval for the chosen interval of analysis.

It is possible to estimate the typical daily consumption profile according to the desired confidence ratio.
