Electrical connection BCL 548
i
The
BCL 548
i
is equipped with four M12 connectors/sockets which are A- and D-coded.
Figure 3.1:
Connections of the BCL 548
i
The
voltage supply
(10 … 30VDC) is connected at the
PWR
M12 connector.
Available at both the
PWR
M12 connector as well as at the
SW IN/OUT
M12 socket are
four freely programmable switching inputs/outputs
for custom adaptation to the
respective application. Detailed information on this topic can be found in chapter 7.2.1 and
chapter 7.2.3.
Standalone operation in PROFINET-IO
During stand-alone operation of the BCL 548
i
, the host interface of the superior system is
connected to HOST/BUS IN. Thus, a star structure (Ethernet structure) is possible.
Network operation in PROFINET-IO
In network operation, the superior system (PC/PLC) is connected to the host interface of
the BCL 548
i
. With the aid of the "switch" integrated in the BCL 548
i
, the bus connection
to the next participant, e.g. a BCL 548
i
, can occur directly via the BUS OUT socket! In addi-
tion to the classic "star topology", a "linear topology" is thus also possible
