PEF 21624 E V2.2-G application field and working principle

PEF 21624 E V2.2-G is an Ethernet switching device designed to meet the requirements of industrial Ethernet applications. This device provides an efficient and reliable solution for communication between Ethernet stations, improving accuracy, speed and communication efficiency. In terms of application fields, PEF 21624 E V2.2-G can be used in a variety of industrial control and monitoring applications, such as machine control, industrial automation networks and large-scale industrial systems.

In terms of working principles, the PEF 21624 E V2.2-G switching device uses a unique Gigabit Ethernet switching algorithm to ensure data transmission automatically. The network layer information is continuously exchanged between the port nodes and the master switching node. In addition, the device adopts a standard IEEE 802.3 Ethernet protocol, realizing the forwarding of communication packets from the source station after the address or service identification information is recognized. When a problem occurs during the data transmission, the device will switch the communication to an alternate data path.

The switching core of the device is composed of a switch controller and switch memory. The switch controller makes decisions based on user commands and Ethernet protocols, while the switch memory stores the control and connection information of Ethernet ports. When the control unit receives a packet, it uses the address information in the packet to determine the routing of the packet to its destination. The function of the packet\'s time limit is also controlled by the switch memory.

In terms of safety management, PEF 21624 E V2.2-G is equipped with an advanced access control and authentication module. The module can limit port users\' access rights according to the user group, password and key, etc. configured on the device, so as to control the network access of different user groups. In addition, the device also supports MAC address learning and filtering, which can effectively prevent illegal access from outside the recommended access point and ensure the safety of the internal data of each user group.

In terms of transmission performance, the device supports IEEE 802.3u and IEEE 802.3ab auto-negotiation functions, which can automatically detect the transmission speed and automatically match the corresponding connections, thus providing transmission with higher performance and better reliability. In addition, the device also supports IEEE 802.3x Full Duplex flow control, which can reduce collision ratio and effectively improve transmission efficiency.

PEF 21624 E V2.2-G is an ideal choice for industrial Ethernet applications due to its high performance and reliable data transmission secure network. Through its advanced switching algorithms, access control and authentication module, MAC address learning and filtering, as well as its support for 802.3u and 802.3ab auto-negotiation functions and IEEE 802.3x Full Duplex flow control, this device can provide safe, efficient and reliable data transmission.
