Controllers simplify machines and improve safety

September 2018 IS & Ex

The Allen-Bradley GuardLogix 5580 and Compact GuardLogix 5380 controllers from Rockwell Automation can be scaled from safety system levels SIL 2/PLd to SIL 3/PLe. This scalability can help engineers optimise a safety system design and potentially reduce its costs, while adhering to the latest machine safety regulations. The high performance controllers also use increased processing power to achieve faster reaction times and shorter safe distances. This can help create smaller machines, save valuable floor space and increase operator efficiencies.

“Many engineers build safety systems to a higher safety level than an application requires,” said business manager Christo Buys. “Such systems end up having more components than they need, leading to increased complexity and costing more than they should. Our new controllers allow engineers to right-size a safety system and its cost to meet appropriate safety levels without excess.”

The new high-performing controllers can also help engineers consolidate the number of controllers they use in complex machines. Having a single high performance controller for both standard and safety control can help improve productivity and reduce the system’s cost, complexity and cabinet size.

Other benefits of the new controllers include:

Greater communications capacity: Embedded gigabit Ethernet on the GuardLogix 5580 and Compact GuardLogix 5380 controllers provides greater communications capacity to support the growing number of smart devices. This can help engineers meet data intensive smart manufacturing goals without adding extra hardware. It also can help future proof machines for end-users that may someday need to collect and share more data.

More productive machines: The controllers, when used with the Studio 5000 integrated development environment and Kinetix 5700 servo drive, support new safe-stop, safe-speed, safe-position and other safe-monitoring functions. These safety functions can create more flexibility in safety system operations, for example slowing down a machine instead of stopping it when a worker approaches. This can improve machine productivity while still achieving a desired level of safety. These new functions are implemented using built-in safety instructions available in the Studio 5000 software. Engineers can also use the safety functions to support applications like collaborative robots. The system can detect when a human comes too close to the robot and either slow down or stop the robot’s motion. The GuardLogix 5580 and Compact GuardLogix 5380 controllers are TÜV certified for functional safety.
