B&R SafeLOGIC: The Brain of Integrated Functional Safety.
In the dynamic world of industrial automation, safety is not an extra, but a fundamental requirement. With its SafeLOGIC safety controller, B&R offers a powerful and flexible solution that not only meets the most demanding safety standards but also optimizes the productivity and efficiency of machines and systems.
What is SafeLOGIC?
SafeLOGIC is B&R’s programmable safety controller, designed to handle all core tasks within a safety application. It works in conjunction with the Automation Studio development environment and the safety-specific tool, SafeDESIGNER. Its primary function is to ensure that machines and processes operate safely, even in the event of faults.
There are different variants, such as the SafeLOGIC-X, which is remarkably compact and offers the functionality of a full-featured SafeLOGIC controller, distributing control functions across existing automation components.
SafeLOGIC Key Features
The SafeLOGIC is distinguished by several features that make it a robust and versatile solution:
Configuration Management: SafeLOGIC monitors the security configuration of all modules and devices involved in the application. This ensures that the configuration is consistent and correct across the entire network, which is crucial, especially during module replacement or maintenance.
Parameter Management: In the event of a module replacement, SafeLOGIC automatically assigns the correct parameters to the new module. This eliminates the need for manual parameterization, reduces errors, and speeds up commissioning.
Safety Program Execution: SafeLOGIC executes the safety program designed in SafeDESIGNER. This program, based on logic function blocks, constantly monitors the status of the machine and its components and triggers predefined safety responses in the event of dangerous conditions or failures.
Secure Communication: Uses the openSAFETY protocol (via POWERLINK or UDP) for secure, certified communication between safety modules and other SafeLOGIC controllers. This enables a flexible and scalable safety network, where the addition of new components only requires parameter adjustment on the HMI, without the need to rewrite the safety application.
Blackout Mode: An innovative feature that allows safety applications to continue running even after a network or main controller failure. This ensures continued safety in critical situations.
SafeMotion Functions: Integrated with B&R ACOPOSmulti drive systems, SafeLOGIC enables safety functions such as:
Safe Torque Off (STO): Safe torque disconnection.
Safe Operation Stop (SOS): Safe operation stop.
Safe Stop 1 (SS1) and Safe Stop 2 (SS2): Different safe stop modes.
Safely Limited Speed (SLS) and Safe Maximum Speed (SMS): Safe limited or maximum speed.
Safe Direction (SDI): Safe direction.
Safe Limited Increment (SLI): Safe limited increment.
Safe Brake Control (SBC): Safe brake control. These functions enable intelligent safety responses that prevent the machine from coming to a complete stop whenever possible, increasing productivity.
B&R SafeLOGIC is a cutting-edge functional safety solution that goes beyond a simple “emergency stop.” It offers an integrated, programmable platform that enables machine builders to implement flexible, adaptable, and highly productive safety concepts, protecting both people and investments. Its focus on openness, integration, and efficiency positions it as a solid choice for the demands of modern automation.
