Very interesting tutorial. I would like to a suggestion to use enumeration instead of using step:= 0, 1, 2 etc. You can define them in DUTs or even locally in the function blocks them as " Steps : (WAIT=0, PUSH, DWELL, RETRACT, RESET); " and the use CASE statements to go through different steps.
The reason for this is because step:= 0 has no meaning. Yes there is a comment above but it is not good practice to rely on comments, as the code will get changed and comments get left behind unattended. We should strive to make our code self-explanatory and self-documenting as much as possible.
