In production environments where humans work in close proximity to machines, conventional sensors provide insufficient active protection against injury for operators. By integrating openSAFETY-based light curtains into its automation landscape, B&R is opening up completely new approaches to safety for today's manufacturing facilities.
Light curtains have been used for many years now to protect operators of machinery and equipment. The intelligent light curtain is connected directly to the real-time POWERLINK network. The overlying open SAFETY protocol replaces the hardwiring that used to be necessary for the light curtain.
