profinet switch

divides a high-bandwidth channel into multiple channels with a smaller bandwidth, as if multiple lanes are divided on a single road, and time-division multiplexing transmits the channel multiplexing by allocating the communication packets to different timeslot. Profinet Communication mode is the producer/consumer, each communication node is equal, can send and receive data at any time, so the bus of the kind of "token" control can not be applied

"Industry 4.0" is the hottest topic in the manufacturing industry, so don't talk about this topic are embarrassed to greet the peers. An important part of "Industry 4.0" is the Smart factory, the communication between the factory assembly line equipment, whether the traditional wired connection or advanced wireless connectivity and distributed control, can be achieved through profinet, from a certain point of view can be said that the role of

I'm going to go down to the two and three layers of the switch. A two-tier switch is equivalent to dividing an interface into multiple interfaces, just to provide a lot of interfaces; (if the landlord is not a professional person can ignore the following content) theoretically it can be understood that the switch does not split the broadcast domain, but split the

Today, the tutor told me about the company's network topology, related to the switch, the basic concept of routers and principles, I am not very clear, so on the internet to learn the information to learn a bit, and then feel that this article is good, so it reproduced, but I reproduced not the original text, and did not attach the original link. Here I posted a link to my reprinted article: http://blog.csdn.net/herostarone/article/details/8256235 Two

Two-layer switching technology is a mature development, two-layer switch is a data link layer device, can identify the Mac in the packet Address information, forwarding based on MAC addresses, and recording these MAC addresses with corresponding ports in one of their own. Address table. The specific work flow is as follows: (1) When the switch receives a packet from a port, it first reads the source MAC a

Simply put: Layer-1 switchOnly physical layer protocols are supported (one phone-controlled switch can be called ???)L2 SwitchSupports physical layer and data link layer protocols, such as Ethernet switches.L3 SwitchSupports physical layer, data link layer, and network layer protocols, such as some switches with routing functions. In terms of the ISO/OSI hierarchy, switches can be divided into L2 switches and L3 switches. A layer-2

Click the Label Switch and switch the DIV tab to switch the div Copy codeThe Code is as follows: How does Maxthon2 automatically switch the new tab to the new tab? Khan ...... I'm not doing anything about it. If it's me, I will choose to load the proud game (including configuration data) and reload the proud game.Suppl

1) layer-2 Exchange Technology The layer-2 switching technology is relatively mature. The layer-2 switch is a data link layer device that can identify MAC locations in data packets.Address information, which is forwarded based on the MAC address, and the corresponding MAC addresses and ports are recorded in a local location.Address Table. The specific workflow is as follows: 1) when the switch receives a pa

An instance of VLAN configuration for Cisco L3 switches and L2 SwitchesCisco VLAN implementation is usually port-centric. The port connected to the node determines the VLAN in which it resides. There are two ways to allocate a port to a VLAN: Static and Dynamic. The process of creating a static VLAN is to forcibly allocate the port to a VLAN. That is, we first create a VLAN on The VTP (VLAN Trunking Protocol) server, and then assign each port to the corresponding VLAN. This is the most common me

Ethernet switches are still quite common. So I studied how to use FPGA to achieve Ethernet switch networking perfectly. Here I will share it with you, hoping it will be useful to you. Ethernet networking is one of the fastest growing technologies in the industrial market. Most industrial Ethernet standards use the IEEE 802.3 standard Ethernet protocol. Therefore, these networks can transmit standard network services and real-time data. However, each s
