4.5 Connecting slave devices
Slave devices can only be connected with
Profi
Message
devices. The
Profi
Message
system uses CAN-bus and Delphin CAN Protoco
Delphin
l
(DCP) to connect to I/O modules. A
Profi
Message
device can be fitted
with two I/O modules. The CAN-connection is established internally.
The DCP CAN bus for I/O extensions uses the "Ext. BUS" port. If a
Profi
Message
device has an insufficient number or type of input chan-
nels, a slave device can then be connected to the
Profi
Message
device
).
Connecting the extension bus
Use twisted pair shielded cable (e.g. braided LiYCY 2x0.14 mm2 TP).
Ensure that the start and end connections (i.e. at the master and at the
final slave device) use the supplied 120-ohm resistors. These produce the
bus signal level and prevent interference from signal reflection. The Hi
(CAN High) designated ports must be connected to other devices via Hi,
and Lo (CAN Low) with Lo.
