The Energy server is a compact plug and play gateway and data logger and is an essential part of an entry level energy management system. It collects and stores consumption of WAGES (Water, Air, Gas, Electricity, and Steam) and environmental parameters such as temperature, humidity, and CO2 levels in a facility. The Energy server provides access to reports such as on-board device and circuit summary pages, as well as on-board data logging. Data can be securely accessed in real time or transmitted as a report to an Internet database server. Data is ready to be processed once received by the server. Data is displayed as web pages through energy management services to support optimization of energy performance and cost management. The main features of the Energy server are: real-time data in easy to understand views, dashboard view for historical reporting, automatic discovery of connected Modbus devices, connectivity to the cloud through three media - GPRS/3G, wired Ethernet, or Wi-Fi Ethernet, four supported transfer protocols: HTTP, HTTPS, FTP, and SMTP with proxy management, data logging, gateway functionality Modbus TCP to Modbus RTU or Modbus ASCII, compliant with electrical switchboard environment (temperature, electromagnetic compatibility) and local backup of configuration parameters.
