After the course, you will be able to apply the Modbus protocol

Modbus Primer

Requirements

No basic knowledge is necessary
Basic knowledge about bus systems are helpful, but not necessary

Description

In this course, about the Modbusprotocol, we begin with the history of the Modbus.
You also get to know the data model of Modbus, in the other lections of this course,. This is explained on the basis of practical examples.
One of the bases to the understanding of the Modbus of protocol are the so-called Function codes and their use. Hence, we devote ourselves to this in a special section and get to know together the most important Function codes in their full extent. We will understand what is a Request and a Response and how this is built up.
Also, the construction of a cross communication is explained in Modbus and how the client / server model works. Building up on this knowledge the difference between Modbus RS485 and Modbus Ethernet is explained.
We will end the course, by seeing the learned theory in practical examples.
