Gabriel,
Thanks for the suggestion. I wasn't aware of this function and I'll look into the possibility.
Currently, I do not have an open slot to put an Ethernet Card. I have 3 serial ports being used in my application. Port1 talks to a printer, Port2 talks to 7 servo motors and Port3 talks to 4 bar code readers. I was hoping to use the CanBus port as the PLC bus.
