Today, many safety systems are based on hardware components that must be wired separately from the control network. The consequences are cost-intensive cabling and very limited diagnostics options. Another alternative implements a safety controller that receives all signals directly or via a proprietary safe bus. With these types of systems, however, special cables and specific safe bus components are needed, which results in additional costs.
A third, very innovative, option developed by B&R is Ethernet Powerlink Safety Technology. All safety-oriented mechanisms, which are open and available, are implemented in the data transfer process so that safety-relevant data can be transferred over a standard fieldbus. With this system, safety functionality is completely integrated in the control system and does not require special cabling. The result is said to be a considerable cost advantage.
All relevant standards for safe data transfer, as required by the automation industry, are achieved according to IEC 61508 SIL 3.
EPL Safety Technology is independent of the transport protocol, ie it is completely compatible with other fieldbus solutions such as CANopen. Thanks to its performance and flexibility, Powerlink provides many advantages: it reduces wiring, prevents errors and provides real-time capability and 10x shorter reaction times.
