The open source BiSS (bidirectional/serial/synchronous) protocol implements a fast real-time interface. BiSS enables a digital, serial and secure communication between controller, sensor and actuator. The BiSS protocol is used on the lower sensor/actuator communication level in industrial applications which require fast transfer rates, safety, flexibility and a minimized implementation effort.In addition to its technical advantages, two conditions have established the current global standard: the free BiSS license for applications and the stability and continuity of the protocol since its introduction.BiSS follows the industrial trend of a fully digital communication and increasing functional capabilities with its protocol-specific features like bus structure capabilities and the cyclic redundancy check (CRC) for all transmissions.BiSS with a point-to-point setup is hardware compatible to the industrial standard SSI (Serial Synchronous Interface). Key features are:

• Cyclic bidirectional communication at high speed (up to 10MHz with RS422 and 100MHz with LVDS)
• Line delay compensation
• Consideration of processing times
• Safety capabilities: CRC, Errors, Warnings, Sign of Life Counter
• Bus capability for multiple slaves and devices in a daisy chain
• Suitable for sensors and actuators
