CC-Link IE and PROFINET interoperability specification launched

13 December 2016

The CC-Link Partner Association (CLPA) and PROFIBUS & PROFINET International (PI) announced the launch of a new joint specification at sps/ipc/drives to allow for easy interoperability between CC-Link IE and PROFINET.

The new specification builds on an initial announcement at 2015’s fair, where the network organisations promised to maximise the transparency between the two protocols.

Over the past year a working group has been drafting a specification to provide interoperability between the two protocols. 

Promoting transparency and ease of integration is one of the primary concerns for achieving concepts such as Industry 4.0. Many end users will source production machinery from across the world, which may result in machines in the same plant that communicate via differing protocols. This can lead to increased engineering work to achieve integration, as users are combining heterogeneous architectures that may not necessarily communicate as standard. End users of both networks flagged these challenges to both the CLPA and PI, who reacted quickly via the new cooperation to find solutions.

The new specification will simplify integration and increase freedom of choice for end users who source production machinery globally. After less than a year of work, the specification will be made available to members of both organisations, which will allow them to develop hardware products to support the new specification. 

The specification centres on the functionality of a ‘coupler’ device – which allows transparent communication between CC-Link IE and PROFINET. As a result, both networks can seamlessly share information. This can effectively achieve communication between differing parts of a line on separate networks, hugely increasing transparency and integration.

Karsten Schneider, chairman of PI said: “We are delighted to offer our users direct solutions to their requirements, in conjunction with the CLPA, whose aims are synchronous with our own.”

“The CLPA is pleased to be working with PI and our partners to offer support to end users who need this interoperability. The cooperation between CLPA and PI will directly help to make concepts such as Industry 4.0 a reality,” continues Naomi Nakamura, global director of the CLPA. “Increased openness and accessibility is what our end users demanded, so we are pleased to be able to support them fully with this new specification.”
