Obviously the arduino must then be the client.īuild your distributed automation system with Souliss - To me it looks like the system supports the ModBus basics but in an error case it doesn't follow the ModBus specification. Is there any good and working library available for these? That is what this course is going to do.Īt the end of the course, you will have the knowledge to create your own products, your own custom Modbus master and slave hardware.
