Manufacturers and equipment builders are looking for ways to simplify and standardise safety across their machines and systems. With the new Allen-Bradley Compact GuardLogix 5370 controller from Rockwell Automation, users no longer need separate networks and controllers for safety and motion in applications with up to 16 axes. This makes it easier to design safety into a range of standard and custom machines, and results in simpler system architectures.
“The new Compact GuardLogix 5370 controller has all the performance capabilities of our popular Allen-Bradley CompactLogix 5370 controller, while also providing integrated safety and motion on a single EtherNet/IP network,” said Christo Buys, business manager for control systems, Rockwell Automation, sub-Saharan Africa. “When safety, motion and standard control combine into one package, configuration is easier, wiring reduced and users get better diagnostics. Ultimately, it helps increase machine uptime and plant productivity.”
The Compact GuardLogix 5370 controller also helps users meet global safety standards. It achieves SIL 3, Performance Level e and Category 4 – the highest ratings for machine safety. When combined with the Allen-Bradley Kinetix 5500 servo drive or the Allen-Bradley PowerFlex 527 AC drive, users have integrated safe torque off on EtherNet/IP.
As with other Logix controllers, engineers use the Rockwell Software Studio 5000 software to configure the Compact GuardLogix 5370 controller and develop all elements of their control system. Data need only be defined once, and then easily accessed and re-used across different machine types to speed system development and commissioning.
The controller also includes dual Ethernet ports to support both linear and device-level-ring (DLR) network topologies. Built-in energy storage removes the need for batteries, and a removable 1 GB Secure Digital (SD) card improves data integrity.
Rockwell Automation also will be releasing an on-machine option later this year – the Allen-Bradley Armor Compact GuardLogix 5370 controller. This option allows users to place the controller closer to the application or the machine, which eases installation, commissioning and troubleshooting. The on-machine controller is IP67-rated for wash-down protection and includes quick-connect cabling to ease system wiring.
In addition, a single programming environment for both safety and standard control removes the need to manually manage separate standard and safety memory, or partition logic to isolate safety.
