Ethernet cable redundancy

Compact Link Selector from B&R Industrial Automation Corp. connects Ethernet Powerlink controlled nodes, adding redundancy and reliability. Process control and manufacturing automation often require cable redundancy and long cable runs, but closing a ring can cause cable feedback. Ethernet Powerlink protocol and double cabling can be made into unlimited tree structures. This is a July 2008 Control Engineering North American print edition Product Exclusive.

Compact Link Selector from B&R Industrial Automation Corp . connects Ethernet Powerlink controlled nodes, adding redundancy and reliability. Process control and manufacturing automation often require cable redundancy and long cable runs, but closing a ring can cause cable feedback.

Ethernet Powerlink protocol and double cabling can be made into unlimited tree structures. Devices using a link selector function permit data transfer via the highest quality network lines. The 62.5 mm wide Compact Link Selector module is operated as stand-alone unit, enabling as many Powerlink devices as needed on one network with cable redundancy. The link selector function is integrated in the X20 bus controller BC8884 for connecting an X20 System. Expanding the device with two active X20HB2885 hub modules eliminates the need to wire external hubs.

With two hot-swap-capable modules, inputs and outputs (I/Os) can continue operation uninterrupted—even when a hub is replaced. Similarly, two X20 supply modules can provide redundant supply voltage for the system.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
