Detailed Analysis of the Role of Termination Resistors in PROFIBUS-DP Connectors

PROFIBUS Physical Wiring and DP Connector Diagram From the diagram, it can be seen that when the switch is turned to “ON”, terminals A1 and B1 are connected to the termination resistor, so only A1 and B1 can be connected at the end of the DP network; otherwise, the termination resistor cannot be connected. When … Read more

Understanding the Differences Between Profibus, Profinet, and Ethernet

Understanding the Differences Between Profibus, Profinet, and Ethernet Ethernet is a well-known network standard created by Xerox and developed in collaboration with Intel and DEC. It is the most widely used communication protocol standard for local area networks today, including standard Ethernet (10Mbit/s), Fast Ethernet (100Mbit/s), and 10G Ethernet (10Gbit/s). PROFIBUS is an international, open, … Read more
