Design Package Safe Fieldbus Wrapper IP

Design Package for a safe communication
… Design Packages for a significantly faster time-to-market!


Architecture of Safe Fieldbus Wrapper

The Safe Fieldbus Wrapper IP Design Package is a Safety-relevant software library, which represents a generic communication interface between secure, Ethernet-based fieldbus stacks and the safe device software.

Safe Software Libary as a communication interface

Safety-related software and hardware require a certain safety integrity level. To achieve SIL3 typically 2 MCUs with mutual synchronization and monitoring are used (1-out-of-2-Architecture / 1oo2).

The Safety Fieldbus Wrapper IP Design Package allows the communication between application and various safe fieldbuses.

The specific, secure fieldbus data is converted to an abstraction layer. Thus, different safety stacks can be implemented without changing the interface to the software device application.

This is of great advantage especially in multi-protocol implementations of Ethernet-based fieldbuses, e.g.

  • PROFIsafe
  • FSoE
  • CC-Link IE Safety 

The library can be used for safety projects up to SIL3.
