In the previous video, you learned about what Modbus communication protocol is and the types of Modbus communication used in the industry. Now, as promised, in this video you are going to learn about How Modbus communication protocol works between devices. Each Modbus message has the same structure. Four basic elements are present in each message. The sequence and order of these elements are the same for all messages. This allows for easy parsing of the content of the Modbus message. Check out t
