I have had some bad experience with USB but now I look at my computer and my MP3 player, a USB hard drive, Logitech Web Cam, Mouse and Keyboard are connected to my computer using USB and I am NOT using RS-232 at all!
How does every feel about having a USB port on a PLC or more specifically a motion controller?
Bad points. 5 meters maximum cable lenght between hubs. No IP67 connectors yet.
Good points. Easy. No nodes or address, can connect to multiple PLCs or motion controllers.
RS-232 is going away. I hate proprietory communication links like MPI, SC09 cables and DH-485 boards.
My first choice is Ethernet but this is expensive. What should be a cheaper second choice?
