Electrical connection of the BCL 504
i
As a
PROFIBUS participant
, the BCL 504
i
is equipped with four M12 connectors / sockets
which are A- and B-coded.
The voltage supply (
PWR
) as well as the four freely configurable switching inputs/outputs
(
SW IN/OUT
and
PWR
) are connected there.
The BCL 504
i
is designed for use on the PROFIBUS DP. Available as
HOST / BUS IN
inter-
face is a
DP IN - incoming PROFIBUS DP
for connection to the PLC. Available as a second
physical
BUS OUT
interface is a
DP OUT - outgoing PROFIBUS DP
for setting up the
PROFIBUS DP network.
A USB connection serves as a
SERVICE
interface.
