When I came in today one of our machines would not communicate between the HMI and the CompactLogix L27ERM QBFC1B. I cycled power to the machine a couple times with no luck. When the controller powers on the high speed counter fuse light will turn red for a while and then it will go out and the ok light will flash green. But the other ok light will flash red. I was able to see the controller in rs linx but i could not connect to it in studio 5000. it tells me the connection has timed out. I'm new to this so please be kind. lol
