Hi Lee, Thanks for the reponse.
The PLM LED was not blinking or lit at all. I removed power, waited 60 seconds, restored power to ISY, then to PLM, waited for everything to come up and logged in to the admin console. The current status IS showing for all devices. If I make a change to the state of a device (manually switching it on), I see the change in state in the admin console. PLM light is dim lit green.
Restarted "start linking". PLM light gets a brighter green (not blinking). Eventually it timed out with two errors, first was unable to remove existing links error, second was unable to set high water mark error.
Now when I try "start linking", still closes in a couple seconds.
I am able to add devices manually and communicate with everything. Just the start linking mode that is acting odd.
Thanks!
