[0090]Example

[0091]Figure 5A method of implementation of communication between different terminals, as follows:

[0092](1) The process of establishing a port connection with the terminal device B, terminal device C, and terminal device D, and the terminal device A is established as an example:

[0093](1.1) According to the requirements of the application, when the terminal device A first initiates a connection, generates a port porta and opens a temporary space;

[0094](1.2) The first transfer message terminal source port on the terminal device A side fills in port porta, and its destination port is the fixed port 8888 of the terminal device B; the start connection is set to 1, the control bit is set to 1;

[0095](1.3) The connection request is initiated to the fixed port 8888 of the terminal device B based on the IP address of the corresponding terminal device B;

[0096](1.4) The terminal device B receives the data of the first transfer message, randomly generates an available port portb, fi...

Abstract

The invention provides a message transmission module, a network communication system and a communication implementation method thereof, and belongs to the technical field of industrial automation, and the network communication system comprises an NC-Link information model, a message transmission module, an IP and a TSN; the NC-Link information model is used for acquiring sending data transmitted by sending terminal equipment; the message transmission module is used for establishing port connection between the sending terminal equipment and the receiving terminal equipment, data channels and consumption queues corresponding to the channels, and transmitting the sending data to the consumption queues; the number of the consumption queues is greater than or equal to 1; the data channel comprises a real-time data channel and a non-real-time data channel; and the message format of the transmission message comprises a terminal source port, a destination port, a data state, a timestamp, a data packet serial number, a data packet confirmation number, start connection, termination connection, response, control and data. The method is compatible with the multi-source heterogeneous numerical control system and the real-time accuracy of data transmission.

Description

technical field [0001] The invention belongs to the technical field of industrial automation, and more specifically relates to a message transmission module, a network communication system and a communication realization method thereof. Background technique [0002] With the continuous improvement of the digitalization of the production process, industrial communication is required to be more and more open, robust, deterministic and flexible. Only a communicative and responsive production line can ensure fast and reliable production of individual products while meeting strict delivery schedules. [0003] Time Sensitive Networking (TSN for short) series standards define a unified technical standard for key services such as real-time priority and clock. Because in the traditional industrial production environment, a large number of industrial applications (such as machine control, process control, etc.) have an urgent need for real-time communication to ensure efficient and s...
