PROFIBUS is defined by the German national standard DIN19245 and the European standard EN50170. In the industrial field, PROFIBUS has become a universal, open, and distinctly communicative fieldbus standard. PROFIBUS is a fieldbus technology used for data communication and control at the workshop level for factory automation, enabling a communication network from the field device … Read more
PROFIBUS interface is an RS485 serial port, typically using a SUB-D female connector, with the pin definitions as follows: Pin 3 is connected to the signal line B (red) of the PROFIBUS cable, while pin 8 is connected to the signal line A (green). Pins 2 and 7 provide a 24V power supply which can … Read more
1. Overview This article introduces the configuration of FANUC Robot Profibus communication as a slave, with a master station being a PLC that has Profibus DP functionality. The main steps are as follows: 2. Operation Steps 1. Confirm the Robot Profibus Functionality First, confirm whether the robot is equipped with the Profibus functionality. Select the … Read more
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

▼ Click the card below to follow me ▲ Click the card above to follow me Today, let’s talk about the communication protocols of Siemens PLC. In automation control, the “dialogue” between devices is crucial. Just as people need a common language to communicate, industrial devices also require a “common language” to exchange information. This … Read more
》》PROFIBUS DP to Modbus/TCP Gateway Operation Guide Abstract： This article takes the NT100-RE-DP gateway as an example to implement communication between Modbus/TCP Client and PROFIBUS DP devices, thereby integrating PROFIBUS DP slave devices into the Modbus/TCP network. The following will gradually demonstrate the configuration steps of this gateway, which are similar for other models in … Read more
