Compact controller and data logger | NEW: "Node-RED"

Simple control and energy monitoring in buildings, machines, and systems

The EWIO₂ device families are high-performance data loggers and mini controllers (see variants) with numerous interfaces for applications in energy monitoring and energy management systems in accordance with DIN EN ISO 50001, as well as for automation tasks in buildings, machines, and systems. Small control tasks can be created intuitively and easily with
the graphic programming interface “Node-RED”, integrated in the web server via drag & drop.

In the process, prefabricated nodes are linked together to form program flows. Countless flows and nodes from different manufacturers and categories (palettes) can be loaded from the large Node-RED community into the development environment and used.

Two Ethernet-Ports with Daisy Chain function and the WLAN interface^* are predefined for connection to a LAN or WLAN network and for daisy chaining several network participants. The EWIO₂ features the communication protocols Modbus TCP and BACnet/IP (*variants) for connection to the management (e.g., building management system) or automation level (e.g. controllers). Sensors and consumption meters of different media (e.g., energy, water, gas and heat) can be connected and read out via the interfaces M-Bus, S0, Modbus RTU and Modbus TCP. The consumption values of individual data points are stored in the database of the EWIO₂ with a time stamp.

This data can be sent (push) or read (pull) as a CSV file from the database via e-mail (SSL) or FTP (SFTP). The EWIO₂ can also be accessed via Modbus TCP, BACnet/IP, and TCP/IP, and the database queried. A REST-API interface enables direct access to the device from higher-level systems. The configuration, parameterization, and programming of the EWIO₂ is done by the web browser directly on the device, meaning no additional software is required.

The integrated digital and analog inputs and outputs of the EWIO₂-M are designed to connect sensors and actuators from different applications in building or industrial automation.

An integrated micro SD memory card extends the functionality of the EWIO₂-M and can be used for saving settings, data, and applications, as well as a boot drive. Optional expansion modules for converting of physical properties such as temperature or S0 pulses into M-BUS telegrams, the recording of S0 double tariff meters, or Modbus RTU I/Os create countless expansion possibilities for the system involving the EWIO₂-M. The EWIO₂ is available as a device variant with data logger function for energy control or management or as a pure small controller for building or industrial automation with or without WLAN connection.
