Implemention BiSS Communication of Encoder System without Slave Module

摘要

This paper addresses issues that occurs when using an asynchronous serial communication mode instead of encoder communication, such as (bidirectional/serial/synchronous) BiSS communication in an encoder system, and operation without using a slave module when using BiSS communication. Therefore, this paper discusses how to operate using a microcontroller unit (MCU), a field-programmable gate array (FPGA), and a RS422 transceiver chip without using a slave module. It also explains the problems that arise when using the MCU and solves the problem by using the FPGA. The effectiveness of the proposed method is demonstrated by the experimental results.
