Embodiment Construction

[0062] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0063] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is a relationship between these entities or operations. There is no such actual relationship or order between them. For example, "first" and "second" in the first terminal and the second terminal are used to distinguish two different terminals, "first" and "second" in the first communicatio...

Abstract

The invention discloses a protocol conversion method, a gateway device and a storage medium. The method includes the following steps that the gateway device receives source EtherNet/IP messages or source TCP/IP messages sent by a first terminal; the gateway device converts the source EtherNet/IP messages into target TCP/IP messages, or, the gateway device converts the source TCP/IP messages into target EtherNet/IP messages; the gateway device sends the target EtherNet/IP messages or the target TCP/IP messages to a second terminal. The gateway device not only can automatically convert the EtherNet/IP messages into TCP/IP messages, and can also automatically convert the TCP/IP messages into EtherNet/IP messages, so that the purpose that the first terminal and the second terminal of different protocols are directly communicated with each other can be achieved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a protocol conversion method, a gateway device and a storage medium. Background technique [0002] The Ethernet Industrial Protocol (EtherNet Industry Protocol, EtherNet / IP) is a protocol system suitable for industrial environment applications. The EtherNet / IP protocol is widely used in industrial and military fields because of its stability and reliability. [0003] figure 1 It is a schematic structural diagram of the EtherNet / IP protocol in the prior art. Such as figure 1 As shown, the architecture of the EtherNet / IP protocol includes: physical layer, data link layer, network layer, transport layer, session layer, expression layer, application layer; wherein, the physical layer, data layer in the architecture of the EtherNet / IP protocol Link layer, network layer, transport layer are the same as physical layer, data link layer, network layer, transport layer in the arch...
