Safety controller for Profinet networks

The new B&R SafeLogic safety controller allows Smart Safe Reaction technology to be used with Profinet. It's 10 times faster than previous solutions, the company said.


The new SafeLOGIC model from B&R allows Smart Safe Reaction technology to be used together with Profinet. Courtesy: B&RWith B+R's SafeLogic safety controller is available for Profinet networks, Smart Safe Reaction technology can be quickly and easily integrated into Profinet automation applications. 

Based on openSafety, B+R's Smart Safe Reaction product set is the only integrated safety system that can guarantee response times of 10 ms, which is 10 times faster than previous solutions, the company said. The openSafety real-time safety bus system is not bound to one solution and can be used on all conventional Ethernet-based fieldbus network systems up to SIL 3. 

In industries where Profinet has established itself as the most prevalent fieldbus network, there is considerable interest in open safety technology. With the innovative and high-performance features that Smart Safe Reaction technology can provide in combination with openSafety, user requirements can now also be solved on automated machines and systems that use Profinet. 

Product set for Profinet 

B+R meets this demand with a SafeLogic safety controller model for Profinet. It allows execution of the safety-related application program and also handles monitoring the overall configuration of the application, including its parameters. 

The application on the Profinet master CPU has full access to the signals in the network, regardless of whether standard or safety-related channels are affected. The SafeLogic controller also uses openSafety to monitor the system and shut it down if a safety requirement is not met. A wide range of proven functions from the Smart Safe Reaction portfolio is available for implementation. This includes, for example, PLCopen-compliant and TÜV-certified function blocks, secure digital and analog input signals, safe temperature signal detection, and much more. 

The SafeLogic controller in this network can also handle signals from openSafety components such as light curtains, laser scanners and variable frequency drives from other manufacturers.

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.
