ROCK products • OCTOBER 2014 40 New Technologies AUTOMATION & ENERGY EQUIPMENT & TECHNOLOGY Moxa Optimizes Performance of Wireless Industrial Networks Moxa is changing the way industrial net‐ works connect with the introduction of the AWK‐1131A IEEE 802.11n wireless AP/client. With high‐speed transmission rates up to 300 Mbps, the AWK‐1131A delivers a more fluid and stable industrial networking experience, along with proven reliability thanks to advanced protection against harsh industrial environments, including power surges, broad tem‐ perature swings, and vi‐ bration from production machinery. "In today's industrial‐ ized processes, we've entered an era in which standard or legacy net‐ working devices are neither robust nor fast enough to meet pro‐ duction expectations," said Ariana Dri‐ vdahl, product marketing manager for Moxa. "However, by integrating ex‐ tremely rugged features not typically seen in standard wireless products, such as electrostatic discharge protec‐ tion and galvanic isolation on all inter‐ faces, along with its lightning‐fast 802.11n speed, the AWK‐1131A is a major step forward for the industrial market, helping users manage the pace of change and address mission critical reliability issues." According to Drivdahl, the benefit of gal‐ vanic isolation is that it breaks ground loops to help prevent unwanted current caused by different ground potentials from entering the device, therefore better protecting the AWK‐1131A from voltage or other electrical surges up to 500v. In addition, Moxa has increased the electro‐ static discharge (ESD) protection on the AWK‐1131A's power inputs and antenna ports to Level 4 isolation to prevent dam‐ age from external environmental sources. Remarkably, all this has been achieved within a form factor that is one of the smallest in the industry, measuring at a mere 2.29‐in. wide, 4.53‐in. tall, and 2.76‐ in. deep. Like all Moxa networking solutions, the AWK‐1131A includes software features that give it enhanced flexibility across a wide range of applications. For example, Moxa's Turbo Roaming allows the AWK‐ 1131A to roam almost instantly between access points, therefore ensuring a nearly constant wireless connection for complex applications. In addition, Moxa's MAC clone technology lets the AWK‐1131A pass the MAC address of a connected device through to the net‐ work. This solves an issue for SCADA systems where end‐devices such as PLCs are on Layer 2 networks, and both the device and the MAC address must be seen for proper communication. Moxa, Rockwell Switch Mounts Directly on Machine Rockwell Automation has launched the Allen‐Bradley ArmorStratix 5700, its first on‐machine switch. Built with ruggedized IP67 protection, the Layer 2 managed industrial Ethernet switch can be mounted directly onto a machine or application, reducing the overall size and cost of a control cabinet, and shrinking the machine footprint. "In many applications, cabinet space for system‐level networks is limited or non‐ existent," said Mark Devonshire, product manager for Stratix switches, Rockwell Automation. "The ArmorStratix 5700 switch expands the Allen‐Bradley On‐Ma‐ chine offering from Rockwell Automation – an industrially hardened portfolio of products that requires no cabinetry – and leverages pre‐configured, quick‐connect systems and simplified wiring layouts to reduce installation, troubleshooting and maintenance activities." The ArmorStratix 5700 managed switch advances connected enterprise goals by delivering integration of machine‐level data that, due to cost or location, would otherwise remain isolated from busi‐ ness‐level systems. Using the Cisco IOS network infrastructure software, this switch manages the transfer of produc‐ tion data to enterprise‐level databases and information systems for improved decision making. This industrial switch simplifies the de‐ sign and development of machine‐level networks through configuration and monitoring tools. These tools help enable easy setup and diagnostics from within the Rockwell Automation Integrated Ar‐ chitecture system – bridging the gap be‐ tween IT and the automation engineer. The ArmorStratix 5700 Layer 2 switch offers high availability, Quality of Service (QoS), and automated monitoring to help simplify network optimization and convergence. The switch comes stan‐ dard with 8, 16 and 24 fixed‐port con‐ figurations, and each base model comes with M12 Ethernet connectors, SD flash card, dual‐power inputs and a panel‐ mounted design. An expanded ArmorStratix 5700 switch of‐ fering includes 10 and 18 fixed‐port config‐ urations, with 2‐GB ports, hardware‐based IEEE 1588, hardware alarms, and up to eight Power over Ethernet (PoE) ports.
