The past 15 years have been momentous ones for the automation world in general. In particular, they have seen discrete wiring be superseded by fieldbuses, and then Ethernet become accepted as technology robust enough for the shop floor. The CLPA has been at the forefront of these developments all along. CC-Link fieldbus quickly established a leading position in the Japanese market and its world leading manufacturing base. From there, global expansion of end users within the automotive and other industries quickly spread it throughout Asia and beyond. In the process, the fieldbus technology matured and offered additional functionality such as a SIL 3 certified safety network.

The halfway mark saw the introduction of a world first – CC-Link IE, the only open gigabit Ethernet for automation. Although Industry 4.0 was several years away, the CLPA was prescient in forecasting the ever increasing need for bandwidth in manufacturing and responding with a technology that still leads the market today. CC-Link IE soon added additional capabilities too, such that today systems can combine I/O, safety, motion and energy management all on the same cable. Hence CC-Link IE is the perfect choice for the future’s bandwidth intensive applications where real time sharing of large amounts of data is essential and total cost of ownership a key concern. To further increase the adoption of CC-Link IE, the CLPA also introduced the Seamless Message Protocol (SLMP), a way for all kinds of devices to communicate on the network with a reduced development effort.

While its technology maintained an industry leading position, the CLPA itself also did not stand still as an organisation. From its origins in Japan, it quickly became a global organisation with offices across the world, able to support its users wherever they were. The membership of the organisation also showed steady growth, to the point where the CLPA is now one of the largest organisations of its kind, with more than 2,400 partners at this time.

Automation vendors were also quick to embrace the CLPA technologies and a large catalogue of products soon appeared. Today about 300 companies offer over 1,400 products of all different types, ensuring maximum flexibility and freedom of choice for machine builders and endusers alike. This has led to CCLink IE and CC-Link being able to boast a global installed base of close to 15 million devices in a range of different industries.

The last few years have seen the CLPA use its key strength in Asia as a tool to assist partner companies throughout Europe to expand their business in this important market. The Gateway to Asia (G2A) programme was started in order to assist companies to develop and market CC-Link IE and CC-Link compatible devices throughout the Asian market when they join the CLPA and pass conformance testing.

John Browett, general manager, CLPA Europe says: “The world has changed in many ways over the last 15 years, with technology often being the main driver. Anniversaries are a good time to reflect on what has been achieved and put it into a wider context. They are also valuable as they encourage us to look forward and plan for the medium and long term future.

“It is clear that open networks will continue to grow around the world and that the CLPA is strong and getting stronger. Industrial Ethernet clearly has a very dynamic future, and CC-Link IE is set to maintain its leadership position in that area. Over the last few years, CC-Link IE and CC-Link have become more important for European companies; as evidenced by the steadily increasing number of companies becoming partners in Europe, developing products and joining the G2A programme.”
