After an extended beta and testing phase, we are happy to announce the final
release of openPOWERLINK 2.0.0!

The main changes of the new version are a fully restructured and documented
source code base that simplifies getting started with the POWERLINK technology.
While still maintaining compatibility with previous versions, the modularity of
the stack has been improved and the application-near "user part" (stack library)
has been cleanly separated from the time critical "kernel part" (stack driver).
This step allows moving the realtime part to a dedicated communication processor
(e.g. in an FPGA) or into a Linux kernel module, thus delivering high
performance while keeping the stack API in user-space and therefore application
development as simple as possible.... read more
