Functional safety standards can be difficult to manage. Rockwell’s smart safety protocol, GuardLink, can improve and simplify machine safety. GuardLink provides data to make decisions easy in a scalable, easy to install solution.
GuardLink uses taps
that send pulses to a master relay; constantly checking for faults and
monitoring device statuses. This technology allows you to wire in series
without ‘home-running’ a cable back to a safety relay or i/o card – significant
time and labor savings – and still maintain the highest safety ratings (Ple,
SIL 3, Cat 4 Rated).
Add more inputs with no extra work
The taps allow up to 64 safety input devices (32 per input)
per master relay and each tap includes light displays that provide local
indication of a fault. This means you don’t have to search through your plant
to see which device tripped – just look for the blinking red LED.
Using data to make decisions
GuardLink also has an Add-On profile (AOP) for Studio 5000
simplifies integration with descriptive, prepopulated tags. Once you’ve tied
GuardLink into Studio you can pull out diagnostic information: which safety
devices are tripping, when, and why. Users can then log this info and make data

Whether you’re an OEM looking to differentiate your machine,
or an end user looking to improve and simplify your safety systems, GuardLink
can provide significant value.
