The plug and terminal resistor play a very important role in Profibus communication. They are very simple to use and do not require many complex settings; however, due to their simplicity, many engineers overlook some details during use, leading to various communication issues.(1) Structure and Simple Usage of Profibus Plugs Figure 1: Structure of Profibus … Read more
1 Characteristics of PROFIBUS-DP PROFIBUS-DP uses physical layer, data link layer, and user interface for high-speed data transmission at the field level. The master station periodically reads input information from the slave stations and sends output information to the slaves. The bus cycle time must be shorter than the master program cycle time. In addition, … Read more
