HEIDENHAIN CNC
The Heidenhain CNC drive accesses Heidenhain TNC640, iTNC530 and other series of machine tools and machining centers through the LSV2 protocol, and can collect real-time operating data from multiple devices, including program names, spindle override , runing status, spindle tools, PLC points, and more.
For the generic steps, see Create a Southbound Driver and Groups and Tags.
