BUS OUT for the BCL 548
i
To set up a PROFINET-IO network with other participants with linear topology, the BCL 548
i
makes available another PROFINET-IO RT interface. The use of this interface drastically
reduces the cabling requirements, as only the first BCL 548
i
requires a direct connection
to the switch, via which it can communicate with the host. All other BCL 548
i
are connected
in series to the first BCL 548
i
For the connection of two BCL 548
i
, the "KB ET - … - SSA" ready-made cables are pre-
ferred, see table 13.8 "Bus connection cable for the BCL 548i" on page 232.
If you use user-configurable cables, note the following:
Notice!
Ensure adequate shielding. The entire connection cable must be shielded and earthed. The
signal lines must be stranded in pairs.
Use CAT 5 cable for the connection.
Note!
For the BCL 548
i
as standalone device or as the last participant in a linear topology, termi-
nation on the BUS OUT socket is not mandatory!
