Thank you! Cheers!

That's right, Modbus TCP could be used without creating an additional layer. But using Node-RED has it's own benefits, as we can make the data available in the cloud, or transfer it to devices which do not support Modbus TCP but rather OPC UA, for example. So with this approach, we have a kind of server/client which is able to communicate with different devices supporting different technologies.

@@TohidAlizadeh I understand, but you also understand that if we add a node, this may become a problem in the future. If this node exits. In the example, it is clear to me that an exchange can be done easily; in automation they often try to remove unnecessary nodes.

I understand. It is always better to keep it as simple as possible, however, as we will see in my upcoming tutorials, there are use cases for this approach as well. Stay tuned!
