openSAFETY is the first open and only truly bus-independent safety standard available for all industrial Ethernet and fieldbus solutions. This technology makes it easier to implement safety solutions in compliance with current 2006/42/EC machine guidelines as well as other applicable standards. Using the "Black Channel" principle, openSAFETY is the only safety protocol in the world that can transfer secure data via any fieldbus system.
In addition to its high degree of interoperability, the way this protocol communicates ensures that messages are received and processed by all recipients at the same time. This is one of the reasons why openSAFETY is a step ahead of the rest with regard to response times. Furthermore, integration via POWERLINK also drastically reduces response times. This in turn considerably increases the availability of machines and systems.
Using openSAFETY technology has many advantages. Combining faster response times with smaller safety clearances means increased productivity, which is enormously important for machine builders. System operators profit from faster commissioning and changeover times thanks to automated parameterization and configuration services.
In addition to digital I/O, openSAFETY also covers analog and temperature interfaces as well as safe speed measurement up to SIL 3 and PL e. Together with safe drive technology, it enables a large number of extremely fast safe reactions, which provides an opportunity for machine developers to reduce their reliance on emergency stop buttons that can often result in damage.
The wiring of the safety-oriented sensors and actuators is greatly simplified with openSAFETY because they can be integrated into the network at the same remote I/O node as standard I/O. In addition, many safety-oriented components are now equipped with their own bus connection and can be connected directly to the network. In a fully integrated system, there is also no need to wire signaling contacts from the safety system to the standard system.
With openSAFETY, B&R provides complete transparency of all safe and standard I/O channels in one system. This allows modules or machine options not permanently built into a system – including when they must be outfitted with the necessary safety features – to be set up in a standard software project and put into operation in the field by simply selecting the proper configuration on a computer screen.
