AB Ultra 5000 program help

Hi, I have an application using Ultra 5000 drive. I need to turn the motor after an external signal is seen, then follow the external encoder until an another external sensor is seen then stop after an amount of encoder pulses and wait for the next run trigger. It would be nice to run this on a cam profile but this would need generating which would require the run length.
To calculate the run length i would have an enother input and when active would tell the motor to turn until 5 external stops have been seen and then take the average distance of the 5 stop distances.

Any help would be appreciated.

Thanks

Hi all, any assistance please really stuck on this as my C combined with the AB language is very limited.
Thanks
