Ethernet based safety network
The CLPA has announced a significant extension to the capabilities of CC-Link IE Field, by adding a fully IEC 61508 SIL 3 compliant safety protocol layer. This means that with a single open Ethernet based network, system designers can integrate conventional and safety control. Further, compatible safety devices can connect directly to the network, reducing cost and increasing flexibility.
>Rather than having to implement a costly independent safety network, designers can now simply add safety devices as required, using the existing CC-Link IE Field network infrastructure. To maintain the vital safety control, the safety devices are operated by a dedicated safety controller that works independently of the main network controller.
>John Browett of CLPA Europe comments: "In any safety application, dependability and performance are paramount. Machine builders and system designers can choose CC-Link IE Field knowing that its response to emergencies will be immediate. When life or limb is at stake, milliseconds can make the difference between a narrow escape and a serious injury.
