WebAbout Modbus TCP/IP Communications. The Modbus TCP/IP Communications option supports communication with Modbus Quantum programmable controllers using the TCP/IP protocol over an Ethernet network. This enabler supports the following CIMPLICITY features: Polled reads at user defined rates. Poll after setpoint. Triggered reads. 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.
