Helmholz NETLink USB Highspeed USB Gateway for MPI/PROFIBUS
The NETLink USB for programming, projecting and visualization of Siemens S7 PLCs may be connected to any MPI/PROFIBUS interface of the bus system. NETL ink® USB is powered from the USB bus, but also features an optional 24 V DC power supply. The cable connection is 1.2 m long and is designed as active line and thus represents no influence on the MPI/PROFIBUS. The integrated PG socket permits connection of further devices. The connection to the PC is established with the included 3-m-high-speed USB cable. NETL ink® USB allows full transmission speed up to 12 Mbps to MPI/PPI and PROFIBUS. Baud rate is detected automatically and communication to further passive participants on the bus is possible. At the USB end the protocols Fullspeed (12 Mbps) and Highspeed (480 Mbps) are supported. The supplied driver automatically embeds in the Simatic1) Engineering Tools. The MPI/PPI/PROFIBUS is electrically isolated from the external 24 V DC power source and from the USB interface (functional separation). Furthermore, you can perform diagnostics and configurations with the supplied SHTools software. A free download of the latest SHTools version is available on our website www.helmholz.com. Thus, additional functions can be updated at any time by yourself.
