7-1-3 Modbus communication protocol for RS-485
The MODBUS protocol allows an easy communication within types of network architectures,before start to
communication with slave device, set the ID number (
Cn036
) for Servo drive respectively, server distinguish ID
number for controlling specific client station.
Standard Modbus networks combine two transmission modes: ASCII or RTU: ASCII(American Standard Code
for information interchange) Mode and RTU (Remote Terminal Unit) Mode, Use
Cn038 to
select ASCII or RTU
mode.
Coding method
ASCII Mode
8-bits Data consist of two ASCII code.
Ex: Data 26H 1-byte , the ’26’ convert to ASCII code is include character ’2‘
Æ
<32H> and ’6’
Æ
<36H>
ASCII Chart ( 0 ~ 9 and A ~ F ):

RTU Mode
Each 8bits is consist of 2 Hex number (4-bits per Hex number).
Ex.: Data 26H, the data length is 1-byte.
