![]() MODBUS® Protocol is a messaging structure developed by Modicon in 1979, used to establish master-slave/client-server communication between intelligent devices.Modbus devices communicates via serial connections for Ethernet connections. There are two separate thing to consider: physical connection and Modbus software. Like for example, how do I gather outputs/inputs from Modbus? Do I need to do some programming? Or do I need to make an interface board so that the Modbus device and the PC can communicate?Īnyone can help? Please. I am learning more about MODBUS, and I would like to know how I make the Modbus device communicate with the PC. Making Modbus device communicate with a PCMaking Modbus device communicate with a PCI am learning more about MODBUS, and I would like to know how I make the Modbus device communicate with the PC. Modbus RTU - generally serial port, but can be embedded in Ethernet. Modbus TCP - generally Ethernet over TCP/IP.
