Industrial safety refers to the functional safety of machinery, ensuring that both people and the environment are protected from potential hazards that may arise during the operation of industrial equipment. In smart manufacturing, safety involves managing risks to acceptable levels, encompassing not only hazards within the plant (e.g., worker safety) but also those affecting the external environment (e.g., environmental damage).

Traditional safety approaches, such as interrupting the energy supply to bring machinery to a hard stop, rely on hardware-based systems like safety relays and wiring. While effective, these methods can lead to significant productivity losses, extended downtimes, and complex recommissioning procedures. Additionally, static hardware-based systems are less adaptable to intelligent manufacturing processes, where plant layouts and automation systems frequently change.

In response, dynamic safety concepts are emerging as a more efficient alternative. These concepts are based on an integrated approach to automation and functional safety, viewing safety as a cross-device function rather than a hardware characteristic. This allows processes to continue operating in a safely controlled manner without the need for an immediate shutdown every time a fault is detected. However, this dynamic approach is most effective when functional safety is embedded in automation projects from the very beginning of the planning phase.

Key Benefits of Dynamic Industrial Safety:

• Minimized Downtime: Reduce the need for hard shutdowns, leading to less disruption and faster recovery times.

• Increased Flexibility: Adaptable to changing plant layouts and processes, supporting more efficient manufacturing operations.

• Improved Worker Safety: Ensures the safety of workers without compromising productivity.

• Enhanced Productivity: Allows safe operation even in the event of minor faults, keeping processes running smoothly.

By integrating functional safety into smart manufacturing systems from the start, companies can achieve safer operations without sacrificing productivity or flexibility. This approach is crucial in the evolving landscape of Industry 4.0, where industrial environments demand both safety and adaptability.
