Abstract
A multi-node communications system is provided with communications protocol using both static () (pre-determined) and dynamic (. . . ) (run-time determined) consecutive communication slots is used. The system has a number of distributed communication nodes, each node being arranged for communicating frames of data with the other nodes during both the static (. . . ) and the dynamic (. . . ) communication slots. Each node includes a synchronized time basemade up of consecutive timeslots (. . . ). The timebasehas substantially the same error tolerance in each node. For static communication (), a predetermined number of timeslots () are utilized for each static communication slot. For dynamic communication a dynamically allocated number of timeslots () are utilized for each dynamic communication slot. In this way both static and dynamic media arbitration is provided within a periodically recurring communication pattern. Communication jitter is well defined and dealt with, and large oscillator drifts are compensated for.
