Universal plug-and-play communication capabilities give clear view of Asian opportunities

In a recent video made with the CC-Link Partner Association (CLPA), Cognex, the world’s leading machine vision company, explains how it has developed universal plug-and-play communications capabilities. Called Cognex Connect, it allows its technologies to be brought online easily and efficiently. CC-Link, with its predominance throughout the fast-growing Asian market, is a key element of the Connect suite.

Whether the vision system is connecting directly to a PLC or robot controller, or is managed remotely from a networked PC or HMI, Cognex Connect assures a seamless and reliable communications link with all other equipment on the factory floor.

Traditionally, vision systems produce a lot of data, so the need for fast and reliable communications is paramount. The Cognex In-Sight range of cameras is able to process data internally, so that higher level information is transmitted rather than raw data. Cognex Connect helps ensure that vision and automation control are fully connected, ensuring that critical control decisions can be made in real time.

Cognex Connect includes support for the most commonly used open-standard Industrial Ethernet and Fieldbus communications protocols for trouble-free connection to PLCs and other automation devices from a wide range of hardware manufacturers. (Discrete I/O and serial protocols are also available to support older PLCs and devices without network connectivity.)

As a global player, Cognex recognizes that the best future growth potential currently lies in Asia, where CC-Link is far and away the first choice for open communications. For this reason, CC-Link is the most-often specified network in the Cognex Connect suite of communications capabilities. As a further sign of their support for CC-Link, Cognex is also a board member of the CLPA, meaning that they are involved with the strategy and direction of the technology at the highest level. Cognex is also involved with the CLPA’s “Gateway to Asia” (G2A) programme, which helps Western companies develop their business in Asia when they develop CC-Link products.

Currently, China is the main market in the region for Cognex; but other nations including India, Vietnam and Korea, are also rapidly industrialising and also providing opportunities. To be globally competitive, manufacturers in these countries are installing world-class automation systems, whose productivity at least matches, and often betters, current industry expectations.

Open automation networks allow engineers to mix and match control devices and equipment from different manufacturers, safe in the knowledge that they will be able to pass data to one another. Without this, plant owners or machine builders may find themselves “locked in” to a single supplier with a consequent lack of options.

CC-Link was originally developed in Japan by world leader in automation Mitsubishi Electric. It was subsequently transferred to the CLPA to be developed and promoted worldwide as an open network technology. It is offered in a number of formats including a fieldbus and the world’s first and only open gigabit Ethernet for automation, CC-Link IE.

To aid CC-Link’s further development and to support users, the CLPA has offices around the world including several throughout Asia and others in Europe and North America. The installed base of CC-Link is around 12,000,000 devices worldwide. and today, more than 1,300 CC-Link compatible products are made by over 280 different manufacturers. The CLPA has over 2,100 member companies, making it one of the largest organisations of its type.
