Can i use the modbus serial to control my VFD  along with the smooth stepper controller for my I/O?

thanks john

John,

Yes, you can use Mobus and also use a smooth stepper.  I am using serial Modbus to control my VFD via Brain. Ethernet Smooth stepper for motion control and I/O. I am probably not the best guy to instruct you, had to stumble through the whole Modbus-Brain configuration.  I am sure someone here can help you once you get ready.
