I would probably add say 10 objects to the HMI that would display these values. The tag name may be something like SpindleHMIDisplay (array of 10). Then give the operator next 10 / previous 10 buttons. Copy the data from your spindle height array into the tags that the HMI is mapped to in chunks of 10.
When you first navigate to this screen, you would copy from 0-9 from your spindle array to your new SpindleHMIDisplay tag. When you hit next 10, you could copy from 10-19 of your spindle array, and so on. Just make sure you don't allow going less than zero or greater than the size of your array or you will fault the processor.
