5. BiSS C-mode interface
Order code:
BISS
The MXS2 is a Slave device and complies with the “BiSS C-mode interface” and the “Standard encoder profile”.
For detailed information not listed in this manual please refer to the official BiSS website (www.biss-
interface.com).
The device is designed to operate in a point-to-point configuration and has to be installed in a “single Master
– single Slave” network.
ATTENTION:
Never connect the sensor in a “single Master – Multi Slave” network.
CLOCK MA and DATA SLO signal levels comply with the “RS-422 EIA standard”.
5.1 Communication
The BiSS C-mode protocol uses two types of data transmission protocols:
•
Single Cycle Data (SCD):
this is the primary data transmission protocol. It is used to transmit the
process data from the Slave device to the Master device.
•
Control Data (CD):
transmission of a single bit following the SCD data. It is used to read data from or
write data to registers of the Slave.
5.2 Single Cycle Data
SCD (32 bits) consists of the following values: 24-bit position value (Position), 1 error bit (Error, nE), 1 warning
bit (Warning, nW) and CRC checking (CRC, 6 bits).

(24 bits)
Process data to be transmitted from Slave to Master.
The transmission starts with the MSB (most significant bit) and ends with the LSB (least significant bit).
