M-Bus / WLAN / BACnet / Modbus


The EWIO2-MW-BM is a powerful data logger for the energy consumption monitoring and energy monitoring in buildings, on machines, plants and systems. Two Ethernet ports with a Daisy Chain function for the further Data logger and a WLAN interface are available for the connection to the LAN oder WLAN network. In addition, the WLAN interface can be used as an access point for the configuration with a mobile device (e.g. smartphone, tablet, notebook). The EWIO2-MW-BM can be integrated into a Modbus TCP or BACnet/IP network to perform control tasks. The system is paramterised, configured ad commissioned through a platform-independent web browser. The M-Bus and Modbus RTU interfaces enable to read different meters: e.g. electricity, water, gas and heat. Optionally, the measured values can either be sent from the data base (push) or read out (pull) via mail (SSL) or FTP (SFTP), from a BACnet or Modbus controller. Simple functions and control tasks in building or industrial automation can be created and visualized via the graphic programming interface "Node-RED" integrated in the web interface and the numerous digital and analog I/Os. An integrated µSD memory card expands the range of functions of the EWIO2-MW-BM for save settings, data and applications.
