The technology behind netX is based on a highly flexible and programmable multi-processor architecture. This processor network forms the switch, permitting architectures of two ports and more. In field devices, in turn, mostly two-port switches are deployed.
The sets of commands of the processors developed by Hilscher are specially designed for the tasks of the OSI architecture. MAC processors handle the standard-dependent protocol tasks at Layer 2. The protocol processors handle the protocol-specific part for Layers 3 and 4.
Local data buses and shared registers connect these processors to non-blocking industrial Ethernet switches, which support both classic “store and forward” and “cut through” functionalities.
Classic field buses, however, can likewise be implemented in this way, as well as future standards, such as TSN or EtherCAT-G.
For our customers, this architecture can be used very easily via HAL drivers and our firmware. Hilscher has the broadest range of network protocols in Master and Slave configurations on the market in this area.
