Allen-Bradley Compact GuardLogix PACs - models L43S and L45S
The Allen-Bradley Compact GuardLogix programmable automation controllers (PACs) - models L43S and L45S - provide integrated safety, motion, discrete- and drive-control capabilities for midrange applications in a single unit.
They 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 controllers use the same configuration, networking and visualisation environment as the company’s larger-scale systems. This provides machine builders and end users with cost-effective integration of a machine or safety application into the plant-wide control system.
The 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 safety options including safe-speed and safe-direction.
The controllers also support the use of the Allen-Bradley CompactBlock Guard I/O modules and Point Guard I/O modules on EtherNet/IP, enabling fast system configuration and improved sharing of information. Featuring a 1oo2 safety architecture, the controllers are rated up to SIL 3 and PL e.
When used with RSLogix 5000 programming software (v18), the 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 re-used, helping to save time and lower the risk of coding errors.
Manufacturers in the life sciences and food and beverage industries can use the RSLogix 5000 software available with the PACs to manage revision control, fulfil regulatory requirements and help protect intellectual property.
