Use the view switch above the map to show the SCADA network or the Operations network, and the legend to add or remove individual networks; the map re-frames to what is visible. Buildings 3–5 are hidden until you select them. Disconnect a cable or switch off a device and watch the rings heal and the treatment cards respond. Everything is reversible with “Clear all faults”.
A scenario applies faults to the live model. Then use the recovery controls to keep water moving, and watch the treatment cards respond.
How the rings behave: in normal operation the ring supervisor keeps one of its two ring ports on standby so there is no loop. When one cable breaks, the supervisor opens that standby port within a few milliseconds and traffic beyond the break simply flows the other way around. A failed node looks like a single break to the ring. Two separate breaks split the ring, and anything outside the supervisor's piece loses ring connectivity. If the supervisor itself fails, the backup supervisor takes over.
