Flexi Soft is a programmable safety controller (safety PLC) developed by SICK Germany. It meets the highest safety standards — SIL 3 and Performance Level e (PL e) according to EN ISO 13849-1. With more than one million modules installed worldwide since 2008, Flexi Soft is one of the most successful safety controllers in the industrial safety sector.

Its modular design allows flexible expansion of I/O points, fieldbus gateways, Motion Control modules, and relay modules. The license-free Flexi Soft Designer software enables intuitive programming, fast commissioning, and continuous diagnostics. Flexi Soft is the ideal solution for high-safety applications in packaging machines, industrial robots, metalworking machinery, AGVs, and automated production lines in Vietnam.

Applications of Flexi Soft in Industrial Safety

Thanks to its modular design, powerful programming capabilities, and advanced safety features, Flexi Soft from SICK is widely used across many industries in Vietnam. Here are some of the most typical real-world applications:

• Safe Industrial Robots: Flexi Soft, combined with the FX3-MOC1 Motion Control module and AFS/AFM60S Pro safety encoders, provides precise monitoring of position and speed for collaborative robots. The system ensures the robot stops or reduces speed immediately upon detecting human presence in the hazardous area, preventing collisions and fully complying with collaborative robot safety standards.
• Packaging Machines and Production Lines: With Flexi Line technology, Flexi Soft allows safe networking of up to 32 stations in a single production line. When adding or removing stations, the system automatically recognizes the changes without re-addressing, making line expansion highly flexible and significantly reducing downtime.
• Automated Guided Vehicles (AGV): Flexi Soft integrates seamlessly with the S300 safety laser scanner via the EFI interface, enabling automatic switching of protective fields according to steering angle or travel speed. This solution delivers maximum safety for personnel and surrounding objects in internal logistics environments.

Frequently Asked Questions (FAQ)

1. Is Flexi Soft compatible with Siemens, Mitsubishi, and Omron PLCs?

Yes, Flexi Soft is fully compatible and easily integrated with most common PLC systems on the market.

Thanks to its rich selection of fieldbus gateways, Flexi Soft connects directly to PLCs without complex programming:

• PROFINET → Excellent compatibility with Siemens S7-1200 / S7-1500
• EtherNet/IP → Good compatibility with Omron NJ / NX series and many other PLCs
• Modbus TCP → Easy connection with Mitsubishi FX5U and other Modbus-supported PLCs
• Other protocols: EtherCAT, PROFIBUS DP, DeviceNet, CANopen, CC-Link

This enables fast and reliable transmission of safety data and diagnostics, shortening integration time and optimizing your automation system.

2. What do SIL 3 and PL e mean? What are the benefits of Flexi Soft achieving these safety levels?

SIL 3 (Safety Integrity Level 3 according to IEC 61508 / IEC 62061) and PL e (Performance Level e according to EN ISO 13849-1, Category 4) are currently the highest safety levels in industrial automation.

They guarantee an extremely low probability of dangerous failure (PFHd ranging from approximately 0.4 × 10⁻⁹ to several × 10⁻⁹ per hour depending on the module — significantly lower than the SIL 3/PL e requirement) and a Mission Time of up to 20 years.

Flexi Soft, with its SIL 3 / PL e rating, is highly suitable for applications requiring the highest safety integrity, such as:

• Collaborative robots (Human-Robot Collaboration)
• Hydraulic presses and stamping machines
• Safety gates and protected areas
• Safe Motion Control (monitoring of speed, position, SLS, SS1, etc.)
• Automation systems with high risk of injury
