The new Allen-Bradley SafeZone 3 laser scanner with CIP Safety over EtherNet/IP and the new Allen-Bradley GuardShield 450L light curtain with CIP Safety over EtherNet/IP plug-in provide users with greater access to critical data needed to create a more comprehensive picture of machine or production line status.  These devices help to create smart machines that can provide meaningful information so users can better monitor machine health, increase uptime, improve flexibility and enhance safety, while helping to lower total cost of ownership. These smart devices provide diagnostic information that can deliver more valuable insights, such as where safety-related failures are occurring or if workers are following standard operating procedures.  Users can put these insights to work to help improve the productivity and sustainability of their production equipment.

The new SafeZone 3 laser scanner with CIP Safety provides area detection inside a work cell.  The addition of CIP Safety allows users to simultaneously operate multiple safety zones instead of switching from one to another.  It also extends the scanner’s field range and can provides vital diagnostic data over a single EtherNet/IP connection. These capabilities can help to improve productivity, such as by notifying workers with an alarm if they are nearing a hazard to help prevent a machine from slowing down or stopping.  In addition, the CIP Safety capability expands available diagnostic data to alert users of common failures, such as the presence of dust on the scanner’s lens.

The GuardShield 450L light curtain with CIP Safety over EtherNet/IP plug-in can protect personnel from injuries related to hazardous machine motion.  The CIP Safety plug-in gives users more access to diagnostic data to help improve productivity and flexibility. For example, users can see exactly which beams are tripped on the light curtain to better understand the cause of a downtime event.  Or they can take a sample of the light screen every 100 milliseconds to track profiles of products running through it and help identify potential quality issues.

CIP Safety is an extension to the Common Industrial Protocol (CIP), the application-layer protocol for EtherNet/IP.  Smart products that use CIP Safety with technologies, such as GuardLink, help to improve safety and productivity and simplify wiring.  They also offer premier integration with an Allen-Bradley Compact GuardLogix SIL 3 control system by using the Studio 5000 Logix Designer application.
