I made local change to the hostmot2 stepper drivers to both send and receive absolute position encoder style. Behaviour could be changed with configuration parameter.
The change is simple but I am still thinking about protocol because with interpolated position mode there is a need to set parameters. I read Profibus use same protocol on all media but it may be a little bit to complex and I do not know about parameters. CANopen have a dictionary which may be used for parameters and PDOs for real time data but I do not know if it is a good idea to use on other media. Via TCP/IP telnet may actually be a simple method to implement set parameters or a web server but a standard industrial protocol used with ordinary configuration tools are probably better.
