NC-Link Companion Specification

NC-Link by the CNC machine tool interconnection communication protocol standard alliance under CMTBA (China) is a complete 7-part release designed for the interconnection of CNC equipment. The full spec and developer tools are at http://www.nc-link.org.cn/#/norm.  The NC-Link standard competes with MTConnect and the VDW/OPC-UA Companion Specification for Machine Tools. However, NC-Link is built for compatibility with existing protocols while adding localization for the Chinese market.

Proprietary and open-source utilities to co-deploy MTConnect and NC-Link are currently in development with an expected release in mid-2021.
