Modbus tcp speed
WebModbus TCP allows more addresses than Modbus RTU, supports multiple client devices, enables faster transmission speeds, and allows as many server devices as the physical layer can handle. Modbus TCP allows multiple client devices to concurrently send requests to a single server device and allows client devices to simultaneously broadcast … WebModbus is an application protocol that defines rules for messaging structure and data organization that are independent of the data transmission medium. Traditional serial Modbus is a register-based protocol that defines message transactions that occur between master (s) and slave devices (multiple masters are allowed on using Modbus TCP/IP).
