Rockwell Automation has introduced the Integrated Safety Functions Option Module that offers several safety functions based on IEC 61800-5-2 standards for Allen-Bradley PowerFlex 755 and 755T AC drives.  It includes the ability to monitor speed, direction and position on an EtherNet/IP network.

As part of a comprehensive solution, a single Allen-Bradley GuardLogix controller can manage safety and standard control in one software environment, Studio 5000 Logix Designer.  Without the need to write and coordinate multiple programs on different controllers, manufacturers can further simplify the programming process and help to save on training and support costs.

The integrated safety functions option module provides ratings up to and including SIL CL 3 and PLe Cat 4, when used as part of an integrated safety system that includes a GuardLogix 5580ES controller or Compact GuardLogix 5380ES controller.  The option module can be added to the drive at any time.

Networked safety solutions can help to minimize hardware and installation costs by further simplifying machine design and reducing equipment redundancies. With fewer components, manufacturers can reduce the size of panel enclosures and save floor space.
