So maybe what is needed is a "MODbus and LinuxCNC for Dummies" document that takes one through the steps of connecting a MODbus device like a ModIO or a Servo Drive with published MODBus register descriptions all through to using them in the HAL and even including display information on the Axis Screen.
I'm probably going to write up something like that so I hope everyone will be patient with me. There are going to be a lot of dumb questions that later on will seem incredibly dumb but initially need to be asked. I'm sure the information is out there but it appears to be all over the place and much of it out of date.
