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 cable on the BCL 548
i
connection cable for the BCL 548i" on page 232.
The individual BCL 548
i
devices in a linear topology are connected with the "KB ET - … -
SSA" cable, see table 13.8 "Bus connection cable for the BCL 548i" on page 232.
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 13
"Type overview and accessories").
