The Safety Communication Layer of BiSS Safety has been confirmed in Europe for suitability for safety-related communication up to and including SIL3. As a result of this, Hengstler will now offer this protocol for its rotary encoder portfolio. Not only will this meet the steady growth in the use of encoders in safety applications, it will also offer the advantage of a continuous data connection to bus participants as well as high transmission rates.
Hengstler encoders have been able to use the open communication standard BiSS C for the past decade, and this extensive experience with the protocol enabled Hengstler to easily roll it out to the full encoder range. The new protocol is 100% based on BiSS C and Hengstler can point to numerous successful applications where its encoders have played a vital role in ensuring optimum reliability. There is enormous potential for this in the field of functional safety in combination with an ever-increasing number of machine guidelines. To facilitate this, the internal system structure of the encoder is expanded by a number of available blocks.
Significantly, the Safety Communication Layer of BiSS Safety has been certified according to IEC 61784-3:2010 and IEC 61508 Part 1-7:2010. This provides assurances for end-users that it is suitable for safety relevant communication up to SIL3. BiSS Safety, combined with Hengstler rotary encoders, offers the best of both worlds, and allows users to select a quality engineered encoder that offers a manufacturer independent protocol for secure data transmission.
