An MD4 loaded with Iqan 6.08 program wouldn't load the program after being set up and running for a while - not seeing the address tag. I loaded it back to the 6.07 version of the program and the MD4 started up without any wiring changes - the address tag (0) was attached the whole time. Another machine running a 6.08 program (different program and machine from above) - Our PDI people saw the same message and had to cycle the key to make it go away. The address tag wiring seems to be good on both machines. I will report back if we see any problems after loading the 6.07 program back in.
