An EtherChannel (or port group) is a group of two or more Fast Ethernet or Gigabit Ethernet switch ports bundled into a single logical link, creating a higher bandwidth link between two switches. Each EtherChannel can consist of up to eight compatible, configured Ethernet ports. The switch supports up to six EtherChannels.
With Flex Links, you define an active uplink interface and a backup uplink interface. The figure below shows the process by which Flex Links converge a redundant star topology.
Food and pharmaceutical makers can better protect the integrity of their products using new hygienic industrial control hardware from Rockwell Automation. The new Allen-Bradley Kinetix VPH hygienic servo motors and a new stainless-steel version of the Allen-Bradley PanelView Plus 7 graphic terminal both help minimize contamination during production and ease compliance.
Can a PanelView Plus 6 or 7 support USB speakers for audio output? Our latest Tech Files post answers the question.
HMS Industrial Networks presents a new family of network connectivity products based on the Anybus technology, which enables ControlLogix and CompactLogix controllers on EtherNet/IP to seamlessly communicate with Modbus, PROFIBUS, DF1 and serial devices.
Resilient Ethernet Protocol (REP) is a technology implemented on Cisco distribution switches and Cisco IE and Rockwell Automation Stratix IES. REP is designed to provide fast network and application convergence in case of a media or network failure, without a negative impact on most network applications.
Device Level Ring (DLR) is an EtherNet/IP protocol that is defined by the Open DeviceNet Vendors’ Association (ODVA). DLR provides a means to detect, manage, and recover from single faults in a ring-based network.
July 2019 User Group will be an update on Industrial Networking and a look at Device Level Ring (DLR) implementation and architectures.
Current Transformers, or CTs, are important elements in power monitoring and protective relaying applications. A CT will step-down higher line currents to a safe level (typically 0-5 A) for use in control panels. But there is an inherent danger when using CTs. Extreme caution must be taken to […]
Machine designers are required to design safety into more industrial systems than ever. To help them design more easily and meet their other application requirements, Rockwell Automation has seven new safety modules across three I/O platforms. This offers designers both local and distributed safety I/O options and a wide range of performance and connectivity attributes to help improve compliance and machine performance.
