Hello. I recently added stack lights to my UR10 and need green led on when running and yellow led on when stopped.  I have the green Led output set high when program running and low when not running and yellow led set high when program not running. The only problem I am having is when the yellow led output is triggered high when the program stops it stays on when program starts running. I think I have to create a thread to turn it off but I really don’t know. 

Nevermind. I figured it out. 

I realize this is an old post but I'm having this exact same issue, any help on how you figured it out? Thanks
