Encoders are first to support CIP Safety over EtherNet/IP
Rockwell Automation has developed what it claims are the first encoders to support the CIP Safety over EtherNet/IP protocol for safety applications up to SIL 3 / PLe. The Allen-Bradley 843ES absolute encoders are aimed at safety applications that need speed, direction or position-monitoring functions.
The encoders are designed to be used as part of an integrated safety system that includes an Allen-Bradley GuardLogix 5580 controller or a Compact GuardLogix 5380 controller.
As well as the safety functions, the encoders are also claimed to deliver:
• Higher productivity Users can continue production while safely monitoring for speed, direction or position.
• Better visibility By integrating safety with standard controls, operators can access all machine events, including safety events, thus reducing response times.
• Faster designs Integrating safety functions over EtherNet/IP can cut hardware and installation costs and save time.
• More efficient system designs Auxiliary feedback via an EtherNet/IP network on CIP Safety can deliver safety integrity and performance using fewer components.
Options include: three configurable resolutions; solid or hollow shafts; and various flanges.
