AMM80 • SSI, BiSS, & RS-485
6 - BiSS C-mode interface
Order code:
AMM80xx/xxxSC1-...
Lika encoders are always Slave devices and comply with the “BiSS C-mode
interface” and the “Standard encoder profile”.
Refer to the official BiSS website for all information not listed in this manual
(www.biss-interface.com).
The device is designed to work in a point-to-point configuration and must be
installed in a “single Master, single Slave” network.
CLOCK IN (MA) and DATA OUT (SLO) signal levels are according to the “EIA
standard RS-422”.
WARNING
Never install the encoder in a “single Master, multi Slave” network.
6.1 Communication
The BiSS C-mode protocol uses two types of data transmission protocols:
Single Cycle Data (SCD):
it is the main data transmission protocol. It is
used to send process data from the Slave to the Master. For any information
refer to the “6.2 Single Cycle Data SCD” section on page 35.
Control Data (CD):
transmission of a single bit following the SCD data. It is
used to read or write data into the registers of the Slave. For any
information refer to the “6.3 Control Data CD” section on page 37.
