At20 modbus communication was created by Philip Lydin
Hello, im thinking about buying this at20 vfd and im wondering if anyone knows if there is a already a plugin to control it by modbus. Down below i linked to the manual. the parameter addresses are located at page 173-178. If there isnt already a plugin made for this specific protocol i would really appriciate some guidance to get started programming it myself.
Any information is helpful. Regards Philip

If it is real modbus (The HuangYang ones are not, which is why they have a dedicated driver) then you should be able to run it with one of the generic-modbus components, or from Classic Ladder.
linuxcnc.org/docs/stable/html/drivers/mb2hal.html
linuxcnc.org/docs/stable/html/ladder/ladder-intro.html (there are more detailed sections, look on the main LinuxCNC docs page)
And if you are running the development version of LinuxCNC: linuxcnc.org/docs/devel/html/drivers/mesa_modbus.html
