Ideally, aim at dual connection to protective earth (PE), i.e. housing by mechanical assembly and cable shield by the downstream devices. Supplementary information The present manual is intended as a supplement to already existing documentation (e.g. catalogues, data sheets or mounting instructions).

Page 6: Introduction
In the point-to-point configuration, only one device with one slave (sensor) is operated on the master. The BiSS interface is hardware-compatible to the SSI interface in the point-to-point configuration and only requires two unidirectional differential lines.

Page 7: Functional Description
After switch-on or an error, the master must maintain a break of 40 μs prior to the data transmission. This ensures that the BiSS timeout has expired and all slaves are ready for data transmission. Baumer_BiSS-C_MA_EN_V1 00.docx 7/10 www.baumer.com 25.08.2016... -
Page 8: Sensor Data Communication
There is no start bit. The CRC check bits are always transmitted inversely first with the most significant bit. The starting value for the CRC calculation is generally zero. Output format BiSS-C protocol: ERR/NERR WARN/NWARN CRCPOS 0/1 bit 12 bit 9-19 bit 6 bit (inverted) Figure 5 Baumer_BiSS-C_MA_EN_V1 00.docx 8/10 www.baumer.com 25.08.2016... -
Page 9: Control Communication
Note: Before each control frame at least 14 bits with CDM=“0“ must be transmitted. Baumer_BiSS-C_MA_EN_V1 00.docx 9/10 www.baumer.com 25.08.2016... -
Page 10: Register Communication
The error reset is automatically executed at position data reading. BiSS encoders are programmable to allow for customer-specific parameterization. Should you require another different from default, you may approach your Baumer contact for support to ensure proper encoder functionality by the correct configuration. We gladly will be of help.
