Introduction
The following redundancy scenario describes the effects of a failure of an interface module in
an R1 device in the PROFINET ring.
Redundancy scenario
Two fiber-optic cables (redundancy connections)
PROFINET cables (PROFINET ring 1)
PROFINET cables (PROFINET ring 2)
ET 200SP HA interface module → failed
