Electromate: BiSS-C & SSI Encoder Interface Protocols Explained
BiSS-C & SSI Encoder Interface Protocols Differentiations. Absolute encoders are critical components in motion control and automation, providing precise position feedback. Two commonly used serial communication protocols for absolute encoders are BiSS-C and SSI. Both interfaces enable data transmission between encoders and controllers, but they differ in terms of architecture, data integrity, speed, and flexibility. This paper provides an overview of these protocols and highlights their key differences.
