TwinSAFE Safety Technology, TwinSAFE Logic

The TwinSAFE integrated safety solution represents the consistent continuation of the open and PC-based control philosophy from Beckhoff.

Due to their modularity and versatility, the TwinSAFE terminals fit seamlessly into the Beckhoff control system.

All essential areas of automation technology are covered. TwinSAFE offers solutions in the control, I/O, motion, automation, and MX segments. All components can be combined across areas to provide a fully comprehensive security architecture for almost any customer application.

Flexible implementation of safety solutions with TwinSAFE:

• comprehensive software support
• high-performance safety controllers in various form factors
• safety components for different environmental conditions
• safety components in the most diverse granularities for optimum adaptability

With the introduction of the new Logic generation (from EL6910 on), Beckhoff has triggered a revolution in safety technology. The functionality of the TwinSAFE Logic is integrated in all new TwinSAFE components, thus considerably extending the range of potential deployment and application scenarios. TwinSAFE is becoming significantly more flexible in terms of adaption to individual safety requirements of a machine. For example, the integrated TwinSAFE Logic functionality in a digital input component (e.g. EL1918) can be used to selectively preprocess sensor data directly on the component. This preprocessing function can be developed separately and likewise verified and validated separately. If a central safety controller – central from a safety technology perspective – exists, it therefore only has to process the resulting sensor data. Special knowledge for ensuring proper preprocessing is then no longer needed, reducing the complexity of the centralized safety application and in turn simplifying validation and verification of the centralized safety application.

Application scenarios of the integrated Logic:

• specific preprocessing of signals directly by input components
• fast local responses through localized safety applications
• efficient and flexible modularization without additional costs
