Design Package Safe Fieldbus Wrapper IP
… Design Packages for a significantly faster time-to-market!
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.
Architecture of Safe Fieldbus Wrapper
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.
- CC-Link IE Safety
The library can be used for safety projects up to SIL3.
