In addition to sensors, fieldbus, interface and connectivity solutions, this firm now also offers a new product line of human machine interfaces (HMIs). The VT250 (photo) is the first model available — other models will follow next year — and it provides visualization, controlling and variable gateway functionality for communication between fieldbus structures and realtime Ethernet. The VT250 has a 5.7-in. touchscreen, and can be configured as a master or slave, regardless of the communication direction. Providing two realtime Ethernet ports, the VT250 allows the user to set up a line topology. A communication port supporting RS 232 and RS 485, and the additional USB port are also included. — Hans Turck GmbH & Co. KG, Mülheim an der Ruhr, Germany
