Only to set and adjust the cutting current, air pressure, type of cut (normal, arc always on (mesh cutting), or gouge) and a few other settings in the manual I can't remember off hand
Thc is all done in the controller (oops!! Edit... well the up and down motion is... the voltage is sensed in a thc controller)
Modbus will only automate your setup so you could store it within your tool settings (select tool by material and thickness and the software holds the voltage ampage, air pressure settings too which are sent to the thc and to the plasma when the gcode is initialised (I do it that way with my machine for thc, store the voltage and pierce delay in sheetcam... I could store the amps and air pressure but could not use the info automatically with a hyperthem pmx 45..
