Biss-C Data Transmission; Recommended Line Termination And Shielding - Kübler Sendix SIL Serie Instrucciones De Uso

4.3 BiSS data transmission
The BiSS-C-Interface features bidirectional isochronous communication between sensors, actuators
and industrial controllers. This purely digital link and its protocol have been designed for maximum
performance, transmission reliability and security.
Without affecting the payload data of measurements or interfering with control cycles, the commu-
nication protocol incorporates a permanent, bidirectional access to slave registers. That way device
parameters and additional measurement data, as well as the electronic ID plate and OEM data, can be
accessed at any time.
The interface master provides for an unlimited number of subscribers the clock signal for simultane-
ously triggered actions. For an example, a typical RS422 link can support frame repetition rates of
10 µs even with data words of up to 64 bits.
Data transmission is fully CRC secured for the bidirectional command and register transfer, as well as
for each single-cycle data channel separately, with an assignation of a start value ensuring channel
identification by safety controls.

4.4 Recommended line termination and shielding

A terminating resistor of 120 ohm must be connected on the data line at the input of the controller.
