The unique Allen-Bradley Stratix series of managed industrial Ethernet switches from Rockwell Automation has been extended to include a Layer 3 model. Allen-Bradley Stratix 8300 managed ethernet switches, offering the same features as Layer 2 Stratix 8000, support Layer 3 functionality such as routing between subnets and VLANs. As a result, Stratix 8300 managed ethernet switches provide communication between segmented networks for better performance, security and protection from broadcast storms on the network.
Both the modular Stratix 8000 and 8300 managed ethernet switches are ideal for use in both IT and manufacturing environments, and use the current Cisco Catalyst switch architecture and feature set, along with powerful configuration tools, helping to provide secure integration with the enterprise network and using tools familiar to IT professionals. This first-of-its-kind operating system allows for easy setup and comprehensive diagnostics from within the Rockwell Automation Integrated Architecture system, and can be configured using Rockwell Software RSLogix 5000 programming software.
These managed ethernet switches automatically generate Logix tags for integrated diagnostics and include FactoryTalk View faceplates for status monitoring and alarming. All of these features are the preferred way for controls and automation professionals to integrate networked devices. Other features that are included in the Allen-Bradley Stratix series of managed industrial Ethernet switches include embedded ‘Resilient Ethernet Protocol’ (REP) high-speed ring protocols that provide network resiliency across switches with a rapid recovery time, allowing networks to survive a cable break and remain in production.
In addition to this, another advanced feature of these switches is the ‘Dynamic Host Configuration Protocol (DHCP) per port’ allows the switch to assign IP addresses to end-devices connected to the switch, allowing easier device replacement; while ‘Common Industrial Protocol (CIP) Sync Time Protocol’ allows automation equipment to achieve clock synchronisation within the 100 nanosecond range and permits synchronisation to within 1 millisecond of world time with an appropriate GPS.
The Stratix 8000 managed ethernet switches also include a removable compact flash card for one-step device replacement and default configurations for the manufacturing
environment. Modular and industrially rated, the product line scales from six to 26 ports, with options for copper and fibre to meet a variety of applications.
