5.2. ModBus Controller
5.2.1. This clause explains the Modbus-RTU Slave Module (MBRSM).
Positioned at level 7 of the OSI model, MODBUS is an application
layer messaging protocol that provides client/server communication
between devices connected on different types of buses or networks.
5.2.2. As a MODBUS Serial Line protocol, MODBUS-RTU (Remote Terminal
Unit) is a Master-Slave protocol which takes place at level 2 (Data
Link layer) of the OSI model. The master initiates the
communication by transmitting the Function Code (a ‘request’) to
the address of a slave and after receiving and processing the
Function Code, the slave returns a message (a ‘response’).
5.2.3. The slaves shall not communicate with each other without the request of the master. Since the
MBRSM is based on the 2 wire (half-duplex) RS-485 communication, the network length limit or the
number of station should follow the standards of the RS-485 communication. To extend the
network, such as adding another segment, repeaters can be used. To ensure stability of the network
system, the network redundancy can be configured to slave redundancy.
5.2.4. MODBUS manages the access of data simply and flexibly. MODBUS supports two data types: a
Boolean value and an unsigned 16-bit integer. Generally, it is common for field devices to have
