Connecting PROFINET IO to interface module via BA LC/FC BusAdapter
Introduction
You connect PROFINET IO to the interface module via the BA LC/FC BusAdapter:
● Optically coupled to glass fiber-optic cables with an LC connector (port 1) or
● Electrically with direct connection of the Fast Connect bus cable (port 2)
To do this, screw the BA LC/FC BusAdapter with the attached Fast Connect bus cable onto
the interface module and insert the LC connector.
You can loop through the PROFINET IO via the integrated 2-port switch. You can use any
port of the BusAdapter for feeding or for looping through. The integrated media converter
converts the signals automatically.
