Connect Beckhoff TwinCAT CNC
TwinCAT CNC objects are read over ADS (TF5200, addressed by NetId, IndexGroup and IndexOffset, with variables such as V.A.ACT_POS and V.G.FEEDRATE). OPC UA comes from TF6100 (TC1000 plus a TF6100 licence tier). Siemens Manage MyMachines also offers a Beckhoff TwinCAT3 CNC adapter.
