The Spire system in action. Each of the six computers in the center runs a SCADA Master replica, a Prime daemon, and two Spines daemons. The monitors show three HMIs. One switch connects the replicas to the HMI and a PLC proxy (not shown), while the other is exclusively for communication among the six replicas. Courtesy: John Hopkins University
