Insert the RJ45 bus connector into the PROFINET port (port P3) on the CPU.
Note
Cable support and strain relief
If you are using a FastConne
ct RJ-45 bus connector with 90° cable outlet (6GK1901-1BB20-
2AA0), we recommend you provide strain relief for the PROFINET connecting cable. To do
so, you need a cable tie with a standard width of 2.5
mm or 3.6 mm.
Use it to fasten the PROFINET connecting
cable directly after it exits the bus connector to
the intended cable support on the CPU (on the front directly below the PROFINET interface
X1P3).
