Depending on the configuration, the EWIO, 2-BM is a compact Modbus or BACnet server that connects digital and analog signals from the sensor and actuator level with a Modbus TCP or BACnet/IP network. A variety of tasks in building and industrial automation can be implemented using a Modbus or BACnet client. Simple functions and control tasks in building or industrial automation can be created and visualized using the 'Node-RED' graphical programming interface integrated in the web interface and the numerous digital and analog I/Os. Two Ethernet ports with daisy chain function are available for connecting to the LAN network and linking additional Ethernet I/O devices. The system is parameterized, configured and commissioned using a platform-independent web browser. To expand the sensor/actuator level, MR-I/O extension modules can be connected using a bridge plug (plug & play) and wired to a second interface of the EWIO2-BM, Modbus RTU device. An integrated µSD memory card extends the functionality of the EWIO2-BM for storing settings, data and applications.
