Dec. 1, 2022

GuardLink 2.0 is the world’s most advanced serially connected safety input solution designed to reduce downtime and installation costs, per its maker Rockwell Automation. GuardLink 2.0 offers advanced diagnostics by way of the new Allen-Bradley 432ES GuardLink EtherNet/IP On-Machine Interface or a combination of our Dual GuardLink Relay and EtherNet/IP Interface. GuardLink 2.0 protocol also enables safety-rated control device status reporting and automatic diagnostic reporting to an HMI using CIP Safety over EtherNet/IP, notes Rockwell.

The new 432ES GuardLink EtherNet/IP interface promises to enable users to connect up to 96 safety devices via three independent safety channels. The interface can cascade power to additional interfaces and can keep track of timing and frequency of events to improve maintenance and create process efficiencies. The 432ES supports linear, star and device-level ring topologies, while meeting the highest safety ratings up to SIL 3, Cat 4 PLe.
