PROFINET-IO wiring

A Cat. 5 Ethernet cable should be used for wiring.
For the connection technology transition from M12 to RJ45, a "KDS ET M12/RJ 45 W - 4P"
adapter is available that lets you connect standard network cables.
If no standard network cables are to be used (e.g., due to lacking IP... protection class),
you can use the "KB ET - ... - SA" user-configurable cables on the side of the MA 248i, see
table 14.4 Bus connection cable for the MA 248i on page 84.
The individual MA
"KB ET - ... - SSA" cable, see "Bus connection cable for the MA 248i" on page 84.
For unavailable cable lengths, you can configure your cables yourself. When doing so, make
certain that you connect TD+ on the M12 connector with RD+ on the RJ-45 connector and
TD- on the M12 connector with RD- on the RJ-45 connector, respectively, etc.
Notice!
Use the recommended connectors / sockets or the ready-made cables (see chapter 14 "Type
overview and accessories").
For further information on the topologies, see chapter 4.5.1 "PROFINET-IO".
