This is the 2nd system to do this to me. Both systems are IPO 500 running 4.1.12 w/ vmpro. HG will not follow the out of service fallback. 1st system to do this to me I had to get creative and I found a work around. 2nd system is for a High School and is running full AA. They want to be able to remotely change the service mode through the AA to set main HG to Out of Service in the event of bad weather. I've done this before and it's pretty straight forward. However; this one will not work no matter what I've tried. I shouldn't have to try any tricks for a HG to follow a fallback. Has anyone else come across this? If so, does 4.1.15 fix it? Any input appreciated.
