The open source BiSS interface has turned over a new leaf. The bidirectional sensor interface introduced by iC-Haus in 2002 has now been licensed over 450 times free of charge and has established itself as a worldwide standard in encoder and drive technology. BiSS is bus-compatible and is characterized by the continuous communication of sensor and parameter data, especially in efficient and fast motor control systems. The BiSS Safety protocol is TÜV-certified.
With BiSS Line, the user group defined a transmission technology for the complete BiSS protocol using a single cable with essential, unique features. The successful technical implementation of BiSS Line has been crucial to the establishment of an independent user organization.
On September 28, 2017, 11 members founded the BiSS Association, which hosts an internet platform where providers can share BiSS solutions. The BiSS Association will be represented at the SPS IPC Drives 2017 exhibition in Nuremberg, Germany, at the member booths of sensor, encoder, and drive manufacturers, many of whom are well-known BiSS users who now implement BiSS Line with the BiSS Safety protocol also.
BiSS Line uses standard cable and plug components available on the market and transmits 8B10B-encoded BiSS data via RS485 PHYs in well-known 2-wire or 4-wire technology. The transmission rate is comparatively high at 12.5 MBaud. BiSS Line offers unique features in that it is an open source interface and it has a bus structure for multiple slaves. The implementation of Forward Error Correction (FEC) proved essential for high data integrity in noisy environments or when using low-quality cable and plug connections.
The BiSS Association identified communication integrity in noisy environments (robustness) as a requirement for the acceptance of single-cable technology in the market. On the internet platform www.biss-interface.com, members exchange information on the development of open interfaces and report on their available solutions using the BiSS Interface. These include evaluation boards such as master and slave PHYs, hardware components (iCs, FPGAs, smart sensors), IP, files, licenses and services, sensor systems and encoders, as well as complete drive solutions. The association also recruits new members internationally for collaboration and further development in the field of machine communication. The exchange platform also provides non-members with open access to their solutions and enquiries concerning the BiSS Interface.
