SCADA network with 31 Ubiquiti devices (AF5x, PB, NB, Cameras, NVR and Toughswitches) and 52 devices like Phoenix Contact switches, Rockwell PLCs, HMIs, Koyo , and Stratix router. Yesterday, a link was up but data passing...they rebooted a Toughswitch and blowers in treatment plant turned off where Stratix router is connected to this PLC. Toughswitch is powering 6 cameras, one AP and last port connects to Phoenix Contact switch where AF5X back haul is connected. Two PLCs and HMIs on same switch...we tested the reboot scenario and it did shut down blowers. We broke the connection between our Phoenix Contact switch and Stratix router and issue disappeared. Our devices are on 192.168.1 x and blower room devices in 10.10.254.x subnet. We are not responsible for Stratix and our SCADA network doesn't currently poll any devices at this blower room. We got everything back on line but with no physical connection between both, rebooted Toughswitch and no more issue. We stopped due to thunderstorms, but wondering if you guys have suggestions or ideas. Thanks
