HTTP was originally designed to provide a way to publish and receive HTML pages. TCP (Transmission Control Protocol, Transmission Control Protocol) is a connection-oriented, reliable, byte stream-based transport layer communication protocol defined by RFC793 of the IETF. In the simplified OSI model of computer networks, TCP completes the functions specified by the fourth layer transport layer, and User Datagram Protocol (UDP) is another important transport protocol in the same layer.

With the Modbus protocol, control devices produced by different manufacturers can be connected into an industrial network for centralized monitoring. Modbus defines a message structure that controllers can recognize and use regardless of the network over which they communicate. When communicating on a Modbus network, the Modbus protocol determines that each controller needs to know their device address, identify the message sent by the address, and decide what action to take. If a response is required, the controller will generate a feedback message and send it using the Modbus protocol. On other networks, messages involving the Modbus protocol are converted to the frame or packet structure used on this network.
