If I'm buying a machine that will be custom made for me, I will specify the controls to match my spare parts and knowledge on site (or software licenses already purchased) to save money in the long run (in terms of parts and possibly down time).
If I'm buying a machine that is mass made (within reason for industrial equipment), I won't bother specifying how the task is achieved. And although I would have other reasons, the major one is that if someone mass makes anything, they would have put in a lot of time testing and improving the system... a lot of them will even issue bug fixes or product bulletins with fixes or changes to the machine post sale.
If I deviated from their spec, no one is going to put that time in for that one customer in another country and I'm left to my own devises (or paying to get people in) to sort an issue.
Sadly, I've seen this happen in two occasions... one that I'm trying to sort out now and another one with massive (as in millions of dollars of parts and downtime) repercussions because the people in charge of the automation decided that they did not want to have a computer running their control system.
