Cant set up One CNC with my Doosan

Hi all, new on here so hope i have this right. We have been using OneCNC for a few years now, paired up with XYZ Mills. We have now got a Doosan DNM5700 operating with Siemens Sinumerik 828D. Neither party is being very helpful in getting the two speaking to each other. To me it really should not be that difficult. Does anyone have the post set up and running successfully between these two softwares?

Thank you, any help or advice would be much appreciated.

What are you trying to do? Modbus the units ? Or post processing gcode?
