This article aims to provide a concise yet comprehensive overview of how industrial switches contribute to the formation of industrial ring networks, catering to both traditional industry professionals looking to transition into IIoT and those already working in the. This solution uses Huawei industrial switches to build a production OT ring network. Therefore, ERPS needs to be configured between access switches and industrial switches. Device Level Ring (DLR) is a Layer 2 protocol that enables redundancy in a ring topology, providing fast network fault detection and reconfiguration for industrial networks. DLR is an EtherNet/IP™ protocol that is defined by the Open DeviceNet® Vendors' Association (ODVA). DLR network includes at. DS-3E3700-H Series provide 24 or 48 Giga and 4 fixed 10GE ports onboard with one expansion slot. The high port density satisfy the requirements for hybrid configuration of copper ports and fiber ports at the distribution layer in large sized networks or at the core layer in SMB sized networks. In closing, we highlight the key features of industrial Ethernet switches, and show how to select the redundant ring switch that provides your industrial application with the best performance. provide “reliable data transmission. An industrial ring. A ring network is a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node – a ring.
