A Little about Modbus
A Little about Modbus
Modbus is a serial communication protocol developed by Modicon published by Modicon® in 1979 for use with its programmable logic controllers (PLCs). In simple terms, it is a method used for transmitting information over serial lines between electronic devices. The device requesting the information is called the Modbus Master and the devices supplying information are Modbus Slaves. In a standard Modbus RTU network, there is one Master and up to 247 Slaves, each with a unique Slave Address from 1 to 247. The Master can also write information to the Slaves. Modbus is an open protocol, meaning that it's free for manufacturers to build into their equipment without having to pay royalties. It has become a standard communications protocol in industry, and is now the most commonly available means of connecting industrial electronic devices. It is used widely by many manufacturers throughout many industries
If you what to read the spec go to http://www.modbus.org/specs.php
Shows you that Modbus TCP working with IO
This talks about how it works and can help you write your own Modbus driver.
Data Address
Data Address
Data address are different for every device out there. So you have to look at the slave device to know more its addresses work. If you want to know how the Unidrive M data address work see files at the top of the web-page.
Mission Statement
Mission Statement
Our mission is simple: Help new programmers learn to program. Too many times we have seen others looking for or re-creating the same things over and over. We feel this needs to stop. If we find someone that has produce a quality video we will share it with you. We will strive to make learning as easy as we can without re-creating if possible.
