How to quickly learn about network protocols and network protocolsI. What is the network protocol? Generally speaking, network protocols are a bridge between networks for communication and communication. Only computers with the sa

Network transmission protocol or communication protocol for shortProtocol) refers to the common language for computer communication. Currently, the most popular computer communication is network communication. Therefore, the "Transfer Protocol" generally refers to the transmission protocol for computer communication, such as TCP/IP and NetBEUI. However, the transfer protocol also exists in other computer fo

Officially change the name of the SCL to SuperIO. I. The upgrade mainly includes two aspects: The

Industrial serial port and network software communication platform (SuperIO 2.1) Updated and released, network software superio SuperIODownload 2.1 I. SuperIOFeatures: 1) quickly build your own communication platform software, including the main program. 2) Modular development of devices. By mounting configuration files, you can run the software on the platform.

DHCP can automatically assign an IP address to each computer in the LAN, complete the TCP/IP protocol configuration for each computer, including the IP address, subnet mask, gateway, and DNS server. In this way, the Administrator does not need to manually configure the TCP/IP p

be developed with configuration software because the cost of configuring the software is higher, and some special business or complex business cannot be completed. Based on the actual situation, intends to develop a platform nature of the software, the core part is the data collection part, relatively fixed, the data display, data export and other similar business functions flexible design, change more, relatively large. In the end, everyone can develop under the same platform and maintain

the message as a response, as shown in the following figure. Each network application has its own application-layer protocol, which defines the format and sequence of messages exchanged between processes, as well as actions taken when sending or receiving messages. 　　Figure 1: Communication with each other should be with The application layer is a good place for us to start studying the agreement. We are already familiar with many applications

parts adopt the way of the asynchronous listening data. There are two ways to solve this problem: the first, by receiving the protocol driver to obtain the device ID to identify the corresponding device. The second, the device set by the IP address to identify the appropriate device. The Superio platform now uses the second approach.(3) How does the concurrency mode and auto-control mode achieve the communication interrupt state? In the case of a link failure, send the request command, do not r

, the Sendbytes parameter is the data information to be sent , you can override this interface function to complete a special send data request. Such as:After receiving the data, you need to change the serial port settings to the default configuration to avoid affecting other device-driven communications, such as:Author qq:504547114QQ Group: 54256083Official website: http://www.bmpj.net"Industrial serial port and
