The Modbus protocol serves as a fundamental element in modern computer network systems, with Modbus Transmission Control Protocol (TCP) being particularly vital in the realms of edge computing and industrial computing. Although User Datagram Protocol (UDP) is frequently acknowledged for its superior transmission speed relative to TCP, it is deficient in the reliability that TCP offers. Modbus utilizes the attributes of TCP to ensure accurate data transmission; however, it exhibits inherent limitations when managing large data volumes, which negatively impacts the performance of the communication link. To address this challenge, we propose an innovative approach referred to as Modbus UDP over Time-Sensitive Networking (TSN). This method not only significantly improves transmission performance, but also leverages the benefits of TSN to rectify the reliability shortcomings associated with UDP. Experimental results obtained from the testing platform indicate that this approach can markedly enhance the capacity for lossless data transmission.
