3.4.5.2
Failure of both redundancy connections in S7-1500H > 1500 ms apart
Introduction
The following redundancy scenario describes the effects of a defect in each of the two
redundancy connections in S7-1500H. In this redundancy scenario, the time between the
redundancy connection failures is > 1500 ms.
Redundancy scenario
①
Primary CPU (S7-1500H)
②
Backup CPU (S7-1500H)
③
Two fiber-
optic cables (redundancy connections) → interrupted
④
IO device ET 200MP
⑤
IO device ET 200SP
⑥
PROFINET cable (PROFINET ring)
