Visualizing comms between fieldbus and Ethernet

Traditionally known more for its sensor, fieldbus, interface and connectivity solutions, Turck is now launching a line of human machine interfaces (HMIs) products. The first model, VT250, was on show at November’s SPS/IPC/Drives show in Nuremberg, with additional models following in 2010.

The HMIs serve to provide visualization, controlling and variable gateway functionality for communication between fieldbus structures and real-time Ethernet. The VT250 may be configured as a master or slave – irrespective of communication direction. Based on open standards like CoDeSys and FDT/ DTM, the new HMIs look to guarantee cost-effective interface solutions.

The VT250 provides a 5.7” TFT touch-screen (QVGA) in a compact 212 x 156 x 50 mm housing. On the reverse side is an SD memory card slot, a back-up battery, a fieldbus port that may be configured for Profibus or CAN bus communication (using DeviceNet or CANopen), two real-time Ethernet ports, (allows the user to set up a line topology). A port supporting RS232 and RS485, and an additional USB port, complete the communication package.
