I use PLCs with my machines and it makes things like turrets so easy to automate and really they are quite easy to use or at least the Direct Logic ones are, I have written quite a few ladders for toolchanger, 3 for myself, one for a guy in the USA with a 12 pos turret, one for a guy with a toolchanger on his mill and only a few days ago I did one for a friend that is about to put an 8 pos turret on his lathe.
Having said that it can be done with direct inputs/outputs to/from Mach and VB.
For the sensors you would just need differing magnets at each position. If you look at the example I gave earlier
Pos 1 would have 1 magnet to trigger switch 1,
Pos 2 would have one to trigger switch 2,
Pos 3 would have two to trigger both switches 1 and 2
Etc
