Multi-computer system for generating a master clock to synchronize a cluster of computers forms a real-time system requiring the master clock to fix the system's cycle time.

摘要

Three or more computers (1-3) form a real-time system, in which a master clock is required that fixes the system's cycle time. Each computer has two digital inputs (4a,4b,5a,5b,6a,6b) for reading in a computer number via connector coding. All the computers connect to clock rate outputs (7-9) fed to inputs (7a-c,8a-c,9a-c) for each computer.
