Modbus RTU
Modbus RTU — Speedgoat driver blocks for Modbus RTU
Introduction
Modbus RTU is a serial communication protocol based on a client-server
architecture. Servers provide data in four data tables: Coils, Discrete Inputs,
Holding Registers and Input Registers. Clients access servers to read and write data
according to a function code.
Speedgoat provides a range of serial I/O modules for Modbus RTU communication, all
of which come with Simulink driver blocks. The Modbus RTU protocol stack runs on the
target machine's CPU, whereas the data exchange on the serial line is being processed
by the serial I/O module.
