The fundamental basis of data communication in today’s IP networks is the TCP/IP reference model. Today, we will use a PC to access a WEB server to deeply understand the TCP/IP reference model. As the article is quite lengthy, it is recommended to save it for later reading. TCP/IP Reference Model Computer Network: Simply put, … Read more
Click the blue text to follow us PROFIBUS (Process Field Bus) is a widely used communication protocol in the field of industrial automation. It was developed by Siemens in the early 1980s and standardized in the 1990s. PROFIBUS enhances the level of automation in industrial production by enabling efficient and reliable communication between devices. 1.Development … Read more
The TCP/IP protocol specifies that the minimum frame length for transmission is 64 bytes; any frame shorter than 64 bytes is considered invalid. So, how was this 64 bytes determined? This can be traced back to the CSMA/CD protocol. As is well known, early Ethernet operated on a shared bus, where multiple computers were connected … Read more
1. Design Philosophy of Modbus Protocol Modbus devices communicate using a master-slave (client-server) architecture, where only one device (the master/client) can initiate transactions (referred to as queries). Other devices (slave/server) respond by providing requested data or performing operations as requested in the query. Slaves are any peripheral devices (I/O converters, valves, network drives, or other … Read more
Article Summary This article analyzes twisted pair Ethernet using a mixed-signal oscilloscope as the analytical tool, delving into the encoding of two common types of twisted pair Ethernet. It also examines and verifies the signal transmission of Ethernet at the physical layer, concluding with a practical example comparing the data received by software in an … Read more
