Compumotor 6K 4 used to drive goniometer table

Question

Hello fellow LabVIEw users
I am trying to improve on a goniometer VI that was written some time back for a 6K4 Compumotor. The numerci control button "Move to" rortates the arm on a horizontal surface at the specified angle. I essentially only want to move the goniometer at a certain angle from 0 to 360.
This VI is giving me problems, i.e it runs well but sometimes it stops running all together. I would like to see if it has lost contact with the hardware. There is no way of seeing that now.
I want a critique of the block diagram or any other improvements I can make to the program. I ideally want something that is effiecient readable, scalable etc.
The manuals and communications protocol are attached along with the VI. any criticism would help. Also if someone can point me to an efficiently written VI that has been written already for the 6K compumotor it would be greatly appreciated
Thanks

Hello mhaque,
There are a couple other Discussion Forums with threads regarding the Compumotor 6K4; did you see this more recent one? In regards to your code, have you ever tried highlighting the execution on the block diagram or ran the code with breakpoints to try to narrow down a possible problem time-out area? Do you notice it happens more often when a certain cluster button is pushed to be in a specific state?
Also, older, but from same Parker website: VI Library
