Embodiment Construction

[0026] 1.1 Hardware Implementation Method

[0027] Hardware implementation method: cancel the previous optical module and RJ45 socket, and use the stacker to output differential signals. In order to conveniently put the ordinary electrical port signal on one side, the optoelectronic optional PEC level that can be connected to the ring is placed on the other side of the board. The switch considers signal integrity and anti-interference. The schematic diagram of the system is as follows figure 1 . The actual picture is shown in 2.

[0028] 1.2 Power Design

[0029] The embedded switch power supply adopts 3.3VDC power supply, which is supplied to the board through the pins.

[0030] 1.2.1 Communication between SWITCH and CPU

[0031] The implementation of SWITCH mainly considers the balance and integrity of high-speed signal lines, low-speed signals, the main body clock, and the reliability of the SPI bus, as follows image 3 shown.

[0032] The communication between SWITC...

Abstract

The invention relates to an embodiment of inserted type industrial exchanger which is characterized in that the exchanger can be inserted into various boards according to different requirements of users; a differential bus is output by a stacker, and four terminals can be provided for users; users can peripherally choose the varieties of the terminals according to different requirements; and the second character of the inserted type industrial exchanger is that: since a power supply of the module adopts 3.3VDC, and high-efficiency switch power is used, the efficiency can reach 95 percent, thus providing reliable power supply and ensuring that energy storage of the power supply reaches the requirement of safety and ensuring application in dangerous environments; the third character lies inthat advanced WEB and CLI managements are provided by the inserted type industrial exchanger, which can easily manage each terminal. Each terminal can start the protocol DT-RING and work under a ringnetwork mode.

Description

technical field [0001] The invention can be embedded in various industrial switches, can flexibly change the interface position and form of the switch, and provide convenient conditions for users to embed into various control systems. Background technique [0002] In the past, various industrial field buses were used in industrial fields to connect various industrial devices together to form an industrial control network. However, with the continuous improvement of industrial customers' demands, field buses can no longer meet the increasing new demands of industrial customers. Also due to the inconsistency of various field bus standards, the further development of industrial field bus is limited. As a result, industrial customers turn their attention to the successful Ethernet technology used in the commercial industry. [0003] Industrial Ethernet switching technology is an edge technology that has emerged in the industrial industry in the past two years. It applies commer...
