In 2015, the Safety Communication Layer of BiSS Safety was confirmed by TÜV Rhineland for suitability for safety-relevant communication up to and including SIL3. In the future, Hengstler will offer this protocol for its rotary encoder portfolio in order to meet the steady growth in safety applications.
Since 2007, Hengstler has been offering encoders which use the open communication standard BiSS C. A continuous data connection to the bus participants, high transmission rates and free licenses are to be mentioned as clear advantages. The newly introduced BiSS Safety Protocol is 100% based on BiSS C. Hengstler GmbH, based in Aldingen (southwest Germany) has an enormous experience of countless successful applications in which their encoders play a reliable role.
Hengstler sees enormous potential in the field of functional safety in combination with ever-increasing machine guidelines, increasing number of safety applications. For this purpose, the internal system structure of the encoder is expanded by a combination of available blocks. The Safety Communication Layer of BiSS Safety has been certified according to IEC 61784-3: 2010 ans IEC 61508 Part1-7:2010. It is therefore suitable for safety-relevant communication up to SIL3.
This means that BiSS Safety, combined with Hengstler rotary encoders, will combine positive effects from two worlds. As a customer, one can be sure that Hengstler will successfully extend the encoder portfolio with BiSS Safety, thanks to its decades-long BiSS experience. On the other hand, users benefit from different providers, which offer a manufacturer-independent protocol for secure data transmission.
