ROCKWELL Automation will unveil a suite of products at the upcoming 2005 Safety Show that underpins an entirely new safety control network - DeviceNet Safety.

Offering all the advantages of DeviceNet, DeviceNet Safety allows both standard and safety messages to be mixed on a single DeviceNet cable. This ensures high levels of flexibility and scalability in a truly open safety network.

DeviceNet is a device-level communications network providing connectivity between simple industrial devices (such as sensors and actuators) and higher-level devices (such as PLC controllers and computers). Based on DeviceNet, DeviceNet Safety supports certified fail-safe communications for safety control applications.

"The flexibility, plus cost and installation-efficiencies of the DeviceNet network are now well-proven," said product manager safety, Rockwell Automation Australia, Gary Milburn.

"DeviceNet Safety is a logical evolution of DeviceNet and has been developed in response to industry's demand for a truly flexible and open device-level safety network.

At this year's Safety Show, Rockwell Automation will demonstrate that DeviceNet Safety offers the Australian industrial sector the assured fail-safe communications required in safety control applications, coupled with the proven advantages of DeviceNet."

DeviceNet Safety takes full advantage of DeviceNet's open nature and wide vendor support, providing the end-user with the greatest level of choice and flexibility in a safety network today.

The new DeviceNet Safety suite, part of the Allen-Bradley GuardMaster family of safety products, comprises the 1753-DNSI DeviceNet Safety scanner, plus a selection of 1791DS DeviceNet Safety I/O.

Both the scanner and Safety I/O series are TÜV-certified for up to Safety Integrity Level 3 (to IEC 61508) and Category 4 (to EN954-1).

The DeviceNet Safety scanner provides seamless connectivity between the Allen-Bradley GuardPLC family of safety PLCs and the DeviceNet Safety network. The scanner supports up to 32 safety nodes, or a mix of safety and standard nodes on the same network and is easily configured using familiar RSNetworx series tools.

To learn more about DeviceNet Safety, plus the extensive range of Allen-Bradley GuardMaster machine safety products, visit the Rockwell Automation stand (D50) at the The Safety Show, Sydney Showground, October 26-28, 2005.
