ARCNET's longevity testifies that it is regarded as one of the most robust industrial networking technologies available. The real-time performance of its token-passing protocol along with its simplicity of use makes it ideal for embedded applications. Contemporary Controls is the industry leader in ARCNET connectivity providing wiring hubs, network interface modules (NIMs), network analyzers and ARCNET servers to Ethernet. We wrote the book on Industrial ARCNET and founded the ARCNET Trade Association.
