System redundancy S2
System redundancy S2
An IO device with S2 system redundancy supports redundant ARs.
In a redundant system, an IO device with system redundancy S2 has a redundant AR for
each of the two CPUs (IO controllers). If one CPU fails, the IO device with S2 system
redundancy remains accessible to the remaining IO controller via the AR.
The interface module supports system redundancy S2 on CPUs S7-400H (from firmware
version V3.0) and on CPUs S7-1500R/H (from firmware version V4.2).

Oversampling
Oversampling
The IM 155-6 PN/2 HF interface module supports the oversampling mode of HS modules.
With oversampling, the modules reduce the respective PROFINET send clocks in
isochronous mode.
Additional information on oversampling can be found in the manuals for the I/O modules.
