Ethernet (Ethernet) is a well-known type of network, created by Xerox and jointly developed by Xerox, Intel, and DEC as a baseband LAN specification. It is the most widely used communication protocol standard for existing local area networks, including standard Ethernet (10Mbit/s), Fast Ethernet (100Mbit/s), and 10G (10Gbit/s) Ethernet. PROFIBUS is an international, open, and … Read more
In the field environment of Profibus, we use a variety of systems, and the devices we face interference from are diverse, so the sources of interference are also varied. Many failures caused by interference are more difficult to troubleshoot than other faults. Before troubleshooting interference failures, we need to understand the types of interference. In … Read more
