Automation networks have trended toward ownership by multi-vendor consortiums and also towards using IT networks (especially Ethernet) as a source of technology. Mitsubishi has followed this model through its sup-port of the CC-Link Partner Association (CLPA). The company donated technology to this consortium and is a founding member. Until now the CLPA has dealt with the lower-level sensor and device networks.
With the support of Mitsubishi, CC-Link has grown to become the leading fieldbus in Asia and one of the largest globally when measured by installed base. In 2007, the CLPA announced a new and powerful controller level industrial network, named CC-Link IE. This open-technology network, based on fiber optic 1GB Ethernet, will be managed by the CLPA along with the existing CC-Link fieldbus. The performance and scalability advantages of this new network are now available to all CLPA members.
