The rise of Industry 4.0 and industrial automation has led to a doubling of demand for performance and yield in production management, which has led to an increasing demand for communication bandwidth in industrial applications. It is expected to analyze big data through high-information data acquired by factories to promote a new generation of smart manufacturing. application. In view of this, major manufacturers have joined the development of a new generation of TSN communication protocol standards, pushing Industrial Ethernet to the era of Gbit/s. In order to promote a new generation of smart manufacturing applications, major manufacturers have joined the development of a new generation of TSN communication protocol standards, pushing Industrial Ethernet to the era of Gbit/s. It is understood that the TSN standard is expected to be finalized by the end of 2020.
Li Baiwei, manager of the general marketing department of Renesas Electronics Marketing Department, said that the current mainstream industrial Ethernet communication standards include EtherCAT, Ethernet/IP, Modbus/TCP and PROFINET, and these communication protocols can only be 10~100Mbit/ s Ethernet-based, and these agreements have their own support behind the manufacturers, it is difficult to form a unified standard.
In contrast, Li Baiwei analyzed that the new TSN communication standard, with its high data transmission and priority setting functions, is expected to become the future star of industrial communication applications. He revealed that the existing Industrial Ethernet protocol will become a proprietary network agreement on the TSN network in the future, so such agreements will still exist, but the problem of not replacing each other will arise.
Li Baijun pointed out that the existing industrial Ethernet network is more than enough for existing industrial equipment, but if you want to realize the future industry 4.0, the cloud server will control the vision of the global industrial system, you need to rely on the Gbit/s grade of TSN. The amount of transmission is sufficient.
At present, there are many standards for TSN, but National Instruments (NI), BoschRexroth, Cisco, Intel, KUKA, Schneider Electric, TTTech and other large companies are working with the Industrial Internet Alliance to develop TSN test benches.
Li Baizhen said that the bandwidth defined by TSN itself is relatively large. If 1Gbit/s is taken as an example, it can reach 10 times of the existing industrial Ethernet network. In other words, if the original data can only be cut into 50 frames to access the data, it can be upgraded to 500 time frames through TSN. Therefore, TSN can support all communication protocols applied to motors, sensors and controllers, and define sensing blocks of different data quantities.
On the other hand, today's TCP/IP has dominated many communication protocol standards. Li Baijun analyzed that it is not impossible for TSN to grasp the dominance of industrial communication agreements in the future. In the case of TCP/IP, it is mainly to realize that global IP can be retrieved through TCP/IP. Today, the requirements for priority setting are increasing day by day. For example, it is assumed that an definition is included. The robot arm of the five motors, the data exchange of these motors needs to be prioritized to realize the instant transmission function of the small area network and achieve effective control. Such a trend is a big advantage for TSN Industrial Ethernet, which focuses on the priority transmission of all data exchange priorities.
Li Baiwei revealed that the TSN standard is expected to be fixed by the end of 2020. Now all major manufacturers are looking forward to integrating all industrial IoT information into this new communication protocol in the future. If the global industrial communication protocol runs on the TSN standard, it can easily pass through the centralized cloud server. Support factory network messages in a single system.
