While programmable logic controllers (PLCs) and programmable automation controllers (PACs) have been pitted against each other, many programmers believe that there’s no discernable difference between the two, at least from an application-software point of view.
Though they have different processes, both PLCs and PACs do essentially the same thing: controlling automated processes and machines. The only major difference between the two is that PACs can run computer-based software like Linux or Windows applications.
