Compact GuardLogix integrates safety and motion

Rockwell Automation has introduced a new controller to provide integrated safety, motion, discrete- and drive-control capabilities for midrange applications – all in a single unit. Available in two models – L43S and L45S – the Allen-Bradley Compact GuardLogix programmable automation controllers (PACs) extend capabilities previously available only in the larger Allen-Bradley ControlLogix platform. These include diagnostics and information capabilities that help reduce nuisance shutdowns and prolonged restarts, as well as a single programming environment for enhanced design and development productivity.

As part of the Rockwell Automation Integrated Architecture system, the Compact GuardLogix controllers use the same configuration, networking and visualisation environment as the company’s larger-scale systems. This helps provide machine builders and end-users with cost-effective integration of a machine or safety application into the plant-wide control system.

“The introduction of the Compact GuardLogix PAC opens a new door for many manufacturers with midrange applications who previously did not have the means to implement an integrated architecture,” said Rockwell Automation product manager Architecture and Software South Pacific Region, David Black. “The scalability of the Integrated Architecture system means that manufacturers and machine builders can design their applications using a single control engine and a single development environment, regardless of the application size.”

The Compact GuardLogix PACs can control as many as eight axes of integrated motion over the Serial Real-time Communication System (SERCOS) communication network. When used in combination with the Allen-Bradley Kinetix 6200 servo drive, machine builders have advanced safety options, including safe-speed and safe-direction.

The controllers also support the use of the Allen-Bradley CompactBlock Guard I/O modules and Allen Bradley Point Guard I/O modules on EtherNet/IP, enabling fast system configuration and improved sharing of information. Featuring a 1oo2 safety architecture, the Compact GuardLogix controllers are rated up to Safety Integrity Level 3 (SIL 3) and Performance Level e (PL e) – the highest level of machine safety.

When used with the latest version of Rockwell Software RSLogix 5000 programming software (v18), the Compact GuardLogix controllers can leverage high-integrity add-on instructions (AOIs) for faster commissioning. AOIs encapsulate code for common routines into pre-validated modules that can be easily reused, helping to save time and lower the risk of coding errors. Manufacturers in the highly regulated life sciences and food and beverage industries also can use the RSLogix 5000 software available with the Compact GuardLogix PACs to manage revision control, fulfil regulatory requirements, and help protect intellectual property.

“OEMs and end users are designing contemporary solutions with an eye toward improving safety, achieving higher levels of performance, and realising better integration of a machine with the rest of the manufacturing operation,” said Black. “Through our scalable control platform and advanced configuration environment, manufacturers and OEMs have more opportunity than before to achieve this goal.”
