ABSTRACT:
A multi-node communications system is provided with communications protocol using both static (11, 12, 13, 18) (pre-determined) and dynamic (51, 52, 53. . . ) (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 (11, 12, 13. . . ) and the dynamic (51, 52, 53. . . ) communication slots. Each node includes a synchronized time base5made up of consecutive timeslots (11, 12, 13 . . . , 51, 52, 53. . . ). The timebase5has substantially the same error tolerance in each node. For static communication (10), a predetermined number of timeslots (20) are utilized for each static communication slot. For dynamic communication a dynamically allocated number of timeslots (60) 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.
