4.3 BusAdapter BA 2xFC

PROFINET IO loop-through
2-port switches are integrated in all BusAadapters of ET 200SP HA. These switches allow you
to loop-through the PROFINET IO system from one station to the next.
Number of media interfaces
Avoid a network structure in which there are more than 4 interfaces between electrical and
optical media in a PROFINET IO system between the CPU and any IO device.
From this it follows, for example:
● CPU > Media Interface > IO Device > IO Device > Media Interface > Media Interface > IO
Device > Media Interface > IO Device
Result: Configuration of PROFINET IO system OK
● CPU > Media Interface > Media Interface > IO Device > > Media Interface > Media Interface
> IO Device > > Media Interface > Media Interface > IO Device
Result: Configuration of PROFINET IO system NOT RECOMMENDED
Additional information
● You can find information on the bus cables in the system manual
