Modbus Custom command example
The example implements a Modbus client-server application.
The example acts as both Modbus client and server in a single application. The connection between them is established via Modbus TCP. It is used to send and receive custom Modbus requests and adjusts its internal states based on the request and response.
Running the Example
To run the example from Qt Creator, open the Welcome mode and select the example from Examples. For more information, visit Building and Running an Example.
This example cannot be used in conjunction with other applications. Once the example is started, it can only exchange custom Modbus commands within the application itself. All interactions between the client and server use the Modbus TCP protocol.
The main purpose of the example is to provide some demo code on how to implement a Modbus client or Modbus server handling custom Modbus function codes.
