Ethernet switch eases machine integration

Rockwell Automation has introduced the Allen-Bradley Stratix 5700 managed industrial Ethernet switch that includes an optional integrated Network Address Translation (NAT) feature. The device claims to ease the integration of machines onto a plant’s network architecture, which can prove difficult as OEM IP-address assignments rarely match those of the end-user network IP-address requirements.

The hardware-based NAT feature allows for high performance and simplified integration of IP-address mapping from a set of local, machine-level IP addresses to the end user’s broader plant-process network. This can greatly benefit manufacturers that are integrating identical machines into a production line, especially when multiple equipment builders are being integrated into a common production line. The Stratix 5700 switch NAT feature allows OEMs to deliver their standard machines to customers without having to programme unique IP addresses into them. The end user can then use the NAT feature to more simply integrate the machines into the larger network. Because the machines are identical to their standards, they are easier to maintain.

The Stratix 5700 switch with NAT technology also allows users to have the flexibility to segment or isolate network traffic by determining which devices are exposed to the larger network. By limiting access to certain devices, they can be isolated from broader network traffic, which can help optimize the network performance at the local level, indicated the company.

The Stratix 5700 line of switches is currently available with six, 10 and 20 fixed-port configurations. The product includes features, such as IEEE-1588 time synchronisation, QoS (prioritisation) and Resilient Ethernet Protocol (REP). Additional features also allow for increased network availability, and help improve network performance and troubleshooting-enhanced security. Each Stratix 5700 switch includes: dual-power inputs, input and output alarms, console port, fiber-ready SFP slots, DIN rail mount, and operating temperature range of -40°C to 60°C. Model options include: NAT, two gig ports, SD flash card, conformal coating, and two different software configurations for a total of 20 different models to best match machine and end-user applications.
