Hello,
I always wondered why do we always have to stick to the slow connection speeds of the serial and parallel ports when dealing with PLCs? Why does the communication interface has to be using serial or parallel ports? And why aren't there any PLCs with USB interfaces instead of the normal standard serial/parallel connections/interfaces?
Thanks a lot
