Fullduplex Protocol

Use full-duplex protocol: • over a point-to-point link that allows two-way simultaneous transmission • over a multidrop link where interface modules are able to arbitrate transmission on the link • for high performance applications where it is necessary to get the highest possible throughput from the available medium If you connect an interface module to another Allen-Bradley communication interface module, the modules automatically handle the link arbitration. (For a list of modules that automatically handle link arbitration, refer to page 4–1.)
