2.8: BiSS Encoders (Type 13)
This section describes the use of BiSS encoders in Copley Controls drives.
2.8.1: BiSS Encoder and Drive Communication
BiSS encoders can be single or multi-turn. They provide all digital one way communications to the
selected Copley drive with a bi-directional option.
A train of clock pulses from the drive initiates the transmission of position data by subsequent
clock pulses. The clock and data are wired as differential pairs.
BiSS is an open source digital interface for sensors and actuators. It refers to principles of well
known industrial standards for Serial Synchronous Interfaces like SSI, with additional options:

BiSS B-protocol: Mode choice at each cycle start

BiSS C-protocol: Continuous mode

Synchronous high speed communication
Line delay compensation for high speed data transfer

Request for data generation at slaves

Safety capable: CRC, Errors, Warnings
