This means complete communication is still ensured even if one transition point fails. SANs
connected without RedBox to the decoupled PRP network are an exception from this rule.
Transition between HSR and PRP (non-redundant)
The coupling with a PRP network can also take place non-redundantly. In this case, only one
SCALANCE X-200RNA device is required. The device is connected to the PRP network LAN
A and to LAN B.
Note
This type of linking is not recommended because if the transition point fails, the communication
between HSR and PRP nodes is interrupted.
Network topologies and redundancy
