In this tutorial video, we will learn about Modbus RTU communication and its concepts. We have used L&T LX PLC and Universal Input type 8 Channel scanner module which has inbuilt RS485 port for data communication.
The concept will be same if we want to communicate any instrument which has RS845 port.
In case, we are using any other make PLC, then we have to make ladder logic similar to this one to read modbus slave nodes.
We hope this video will be helpful to begineers, technicians and students who are new to automation systems.
