Introduction
2 channel BiSS-C interface
The EL5042 2-channel BiSS-C interface can be used for direct connection of BiSS-C encoders. As a master, the EL5042 sends the clock signal to the BiSS-C slave (encoder), which transmits the position data. Here a position value can be represented in the process image with up to 64 bits, depending on the resolution of the connected sensor. Furthermore, the EL5042 enables the reading of warning and error status bits, which are represented separately in the process image. Different operation modes, transmission frequencies and frame widths can be configured. The EL5042 supports unidirectional BiSS-C communication.
The EL5042 has distributed clocks, so that the position value can be read with precise system synchronicity. If the distributed clock function is deactivated, the EL5042 cycles are synchronised with the EtherCAT cycle.
