Ignition 61850 Driver seems to drop comms randomly to points, and the points just say "unknown". Also, the "Unknown" status on points comes in every few seconds, but then it clears and all the points come in.
Sometimes the point never comes back in, but a restart of the gateway does seem to bring the DCU back online inside of Ignition. However, the points seem to be taking longer to initially come in with every restart.
