19.2.2 Application
GUID-172BA5D7-6532-4B0D-8C1D-2E02F70B4FCB v1
Dynamic access point diagnostic (RCHLCCH) is used to supervise and assure
redundant Ethernet communication over two channels. This will secure data transfer
even though one communication channel might not be available for some reason
Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy
(HSR) provides redundant communication over station bus running the available
communication protocols. The redundant communication uses two Ethernet ports.
