WebIn theory Modbus TCP/IP carries data at up to 250/ (250+70+70) or about 60 percent efficiency when transferring registers in bulk. Since 10BaseT Ethernet carries about 1.25 Mbps raw, the theoretical throughput is 1.25M/2 * 60% = 360000 registers per second and the 100BaseT speed is 10 times greater. WebModbus/TCP is a third MODBUS protocol which brings MODBUS to IP networks, Modbus/TCP is commonly used by Java applets or ActiveX controls, whereby a user can connected to the embedded web server on an industrial device download the web-based interface for monitoring the end-device and its IO points.
