ModBus/TCP

Modbus is a serial communications protocol which is often used to connect a supervisory computer with a

remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems. To transmit Modbus

over a TCP/IP network, a standard Modbus/TCP protocol is provided. With the support of the Modbus/TCP

protocol, the SCADA/HMI system can directly communicate with the VPort to acquire its operational status.
