Ethernet, Security and Complexity Call for Managed Switches and Routers

More automation processes moving to Ethernet-based control and a growing concern for network security and safety are leading to increasingly managed switch and router functionality.

A virtual local area network (VLAN) is an important function for managed switches, says Charlton Buck, product manager, North America, industrial communications and power networks, at Harting (www.harting.com). "As an example, you may want a packaging line to use certain ports—port 4, filling; port 5, washing; port 6, accumulation—to ensure your manufacturing batch process is not being accessed by potentially malicious users," he explains. "You can set up policies on your batch process ports—port 1, mixing tank; port 2, water softener; port 3, boiler—to restrict user access, or if you want to access a particular server without cross-traffic from other routers."

Fully managed switches, used primarily where Ethernet is the primary automation control, also have applications in network redundancy and remote viewing, notes Mike Wightman, sales manager, fiberoptic products, at Ultra Electronics, NSPI (www.ultra-nspi.com). Managed switches can also trigger email messages to a smart device in alarm situations, and can have self-healing ring (SHR) capabilities to keep the network up and running.

Industrial network traffic increases as companies seek ways to increase their net income and improve margins, Buck notes, adding that more information is being extracted from atypical resources. In some cases, managed switches can make better use of network bandwidth. For example, having machine control on the same network as voice-over-IP (VoIP) phones or printers could slow down the network. "This is similar to using a 100 ft fire hose to water your tomato garden, wash your sports car, and put out a three-alarm house fire," Buck says.

"More and more data are being placed onto Ethernet backbones (such as alarm systems, HVAC, office machines such as printers and servers, audio and video), making the systems more complex," Wightman says. Increasing complexity leads to increased data traffic, and in turn a need for faster processing speeds. "Most industrial networks have standardized on 100 MHz Ethernet switch speeds for their control applications. However, this bandwidth can be saturated quickly if customers also require video over IP for manufacturing surveillance cameras, for example. The GHz platform addresses these concerns, and provides a migration path for control networks should future products require increased data throughput."
