Hi there.
When I do probing in my measuring/compare programs to check fixture/part alignment. Then I use Two datum’s in the table, one that holds the datum for the part, and another one to do the probing in.
When you do this, you can read the values from each datum, and compare measuring data. Part datum is fixed, then using cycle 413 you probe the new part and save the results in the measuring datum, now you got plenty of data to calculate what you want:-)
Use sysread to read the values from the control for your calculations:-)
No standard stuff for this that I know off.
Cheers
