The new Allen-Bradley GuardLogix controller from Rockwell Automation features a two-processor safety architecture and is rated up to a Safety Integrity Level (SIL) 3 functionality. SIL 2 and SIL 3 are the most common safety integrity levels required in machinery and process safety applications, making GuardLogix ideal for a wide range of safety applications. GuardLogix safety controllers are based on the same Logix control engine, networking, and I/O as other Rockwell Automation Integrated Architecture control systems. This design commonality, along with using the standard RSLogix 5000 software, allows for better sharing of information, reduced training costs and faster programming and commissioning. Rockwell Automation Integrated Architecture features multidisciplined control across process, discrete, motion, drive and safety applications, as well as seamless connectivity to plant-wide information systems.

Allen-Bradley GuardLogix™ System Safety Control partnering with the ControlLogix® processor for true integrated safety

GuardLogix uses Rockwell Software RSLogix 5000 programming software, the same development tool used by all Logix Programmable Automation Controllers (PAC). Existing Logix users are already familiar with the system, which helps reduce training and design time, while new users will appreciate the flexible tag-based system that allows programmers to use real names rather than physical addresses. RSLogix 5000 software also helps manage safety memory, so users do not have to manually manage the separation of standard and safety memory or worry about partitioning logic to isolate safety-related data.

During a GuardLogix system development, safety control is managed the same as standard control. Plus, with online editing, the development and debug environment is much easier for users. Once the project is tested and ready for final validation, the user sets the safety task to SIL 3, which is then enforced by the GuardLogix controller. Safety memory is locked to a SIL 3 state, logic is protected, but the standard side of GuardLogix continues to operate like a regular Logix controller. 

Safety memory can be read by standard logic and external devices such as Human Machine Interfaces (HMI) and other controllers. This is a time saver with the elimination of having to set up or condition safety data from a dedicated safety device. Users have easy system-wide integration and the ability to easily display safety status on displays.

GuardLogix controllers leverage Common Industrial Protocol (CIP) Safety on DeviceNet for safety I/O connectivity, and EtherNet/IP for safety interlocking between GuardLogix processors. This allows multiple GuardLogix controllers to share safety data for safe interlocking between different cells/areas.
