5.       COMMUNICATION [MODBUS RTU] PROTOCOL

5.1      Introduction

The unit can be connected in MODBUS/RTU communication data link protocol to messaging
structure, widely used to establish master - slave communications between devices. Each
device must have unique No. node address. Before starting any communication, choose a
baud rate compatible to the host device. A Modbus data sent from a master to slave tells the
selected slave what to do and what information to send back.

5.2      MODBUS Configuration Basic settings

The Basic settings for RS-485 Modbus protocol are as follows :

Band rate
Start bit
Data bit
Stop bit
Parity

9600
