separate connectors. The connectors are linked internally
(bridged), to keep these stub lines as short as possible.
Baud rate and bus cable lengths
The table below gives the maximum cable lengths for
CANopen, subject to the baud rate:
Baud rate in kBits/s 10 20 50 125 250 500 800 1000
Max. cable length in
m 5000 2500 1000 500 250 100 50 25
The max. cable length is the total line length, calculated
from the length of all the stub lines per node (bus nodes)
and the line length between the nodes. The length of the
stub lines per node is limited, and depends on the baud
rate being used (see CAN bus documentation). In the
electronics, you can set the internal interconnection stub
lines to zero. If you are only using one connection pair
(only CANIN or only CANOUT), the cable length corre­
sponds to the stub line length.
Explanations of CANopen communication can also be
found in the online help.
7.3 DeviceNet interface
The DeviceNet interface is based on ISO 11898 and has
been standardized in EN 50325. The hardware is based
on CANopen, so you also need to read through the infor­
mation on the CANopen interface. The constraints are
different, however, compared to CANopen. The interface
design follows the DeviceNet specification Release 2.0
ODVA. The load cell address on delivery is 63.
