EN 61508 Functional Safety Testing of Programmable Logic Controllers
The European Norm EN 61508 is a cornerstone in the functional safety evaluation for programmable logic controllers (PLCs) used in railway and transportation systems. This norm ensures that PLCs meet stringent requirements to prevent faults, which could lead to accidents or failures with significant impacts on public safety.
Our laboratory specializes in performing comprehensive EN 61508 functional safety testing for programmable logic controllers. We understand the critical role these devices play in railway and transportation systems, making it imperative that they adhere to strict standards of reliability and safety.
The testing process involves several stages aimed at ensuring compliance with the norm's requirements. This includes hazard identification, risk assessment, fault model development, software and hardware validation, and finally, safety integrity level (SIL) determination. Our team applies rigorous methodologies to simulate real-world scenarios that may challenge the PLC’s functionality.
Our testing services are designed for various types of programmable logic controllers used in railway applications such as signaling systems, train control units, and automated trackside equipment. The norm covers a wide range of functional safety aspects including fault tolerance, redundancy management, and system recovery.
The process begins with an initial assessment where we work closely with our clients to understand their specific requirements and the intended use of the PLCs. This is followed by detailed documentation of all potential hazards associated with the application. Once identified, these hazards are ranked based on their risk level, which guides subsequent testing activities.
Following this, we conduct thorough fault model development exercises, where various failure scenarios are simulated to assess how the system would respond under different conditions. This helps in identifying any potential weaknesses within the design or implementation of the PLCs that could compromise safety during operation.
In addition to functional testing, we also perform structural testing which involves examining the architecture and design of the PLCs for compliance with EN 61508 requirements. Structural tests ensure that all components are appropriately selected and integrated into the overall system without introducing unnecessary risks or vulnerabilities.
Once all necessary evaluations have been completed successfully, we determine the Safety Integrity Level (SIL) of each tested PLC according to EN 61508 standards. SIL is a measure of how well a safety-related system can prevent hazardous events from occurring due to faults in its components or processes.
- We use advanced simulation tools and software to accurately model complex railway scenarios ensuring precise assessment of the PLC’s performance under various conditions.
- Our state-of-the-art testing facilities provide controlled environments replicating real operational situations, thereby enhancing the accuracy of our test results.

The outcome of this comprehensive testing process is a detailed report outlining all aspects evaluated during the testing cycle. This report serves as conclusive evidence demonstrating compliance with EN 61508 standards, thereby validating the reliability and safety of the PLCs for their intended purposes in railway applications.
By adhering strictly to EN 61508 requirements, we ensure that our clients’ products meet global safety standards, thus enhancing public trust and confidence. Our commitment to excellence extends beyond just meeting regulatory expectations; it includes providing valuable insights into best practices for achieving optimal levels of functional safety.
In summary, our EN 61508 functional safety testing services offer unparalleled expertise in evaluating programmable logic controllers used in railway systems.
