Application Example 4: IEEE 1588 in a PRP Network
RT430 offers the highly accurate IEEE 1588v2 Precision Time Protocol (PTP) combined
with the Parallel Redundancy Protocol IEC 62439-3:2016, ensuring 100 ns accuracy and
high availability in time synchronization over Ethernet networks. In case of failure in one
of the redundant networks, the recovery-time for the PTP is zero. In other words, the
PRP architecture overcomes any single network failure without affecting the data
transmission.
