This might help but it may be out of date as well:
http://linuxcnc.org/docs/2.7/html/drivers/mb2hal.html
basically, at the time, a working modbus vfd driver was edited to use
modio registers instead of the vfd registers. There has been other
independent work done on linuxcnc so searching the linuxcnc wiki might
pull up more information.

First of course the folder linkages should now read linuxcnc rather than EMC2.
Also the document states:
Both Driver Directories Need
modbus.c
modbus.h
findbindir
find-libdir
find-modinc
But the linked folders to download these are either broken or wrong.
These used to be on Michael Haberler's git repository, but it looks like
he doesn't work on cnc software anymore.
The driver code homann_modio.c is also missing LCD support so that needs to be
finished.
Since I have a ModIO, an MPG Encoder wheel and a cheap 4x20 line display
somewhere on route from China I'd like to take a stab at making it work on
LinuxCNC.
Clearly the make files also need to be edited to fix path and filenames like:
emc/usr_intf/axis emc/usr_intf/touchy emc/usr_intf/stepconf
emc/usr_intf/pncconf \
Or has this all been done already by someone?
Thanks
John
