Communications Unit
Section 4-1
Node Number Settings
The setting range for the Communications Unit node numbers varies accord-
ing to the PC, as shown in the following table.
Node numbers vary according to the settings of pins 1 to 6, as shown in the
following table. Node numbers can be set to any value within the range, as
long as they do not coincide with other nodes (Master, Slave) or node num-
bers in the same network.
Note
1.
For details about node numbers and I/O allocation, refer to DeviceNet Op-
eration Manual (W267).
2.
If node numbers coincide with other nodes, overlapping will occur and
communications will not be possible.
Baud Rate Settings
The baud rate can be set using pins 7 and 8, according to the following table.
Note
1.
Be sure to turn OFF the power supply to Slaves (including communications
power supply) when making the setting.
2.
Set the same baud rate for all the nodes (Master, Slaves) on the network.
Not only can Slaves with a different baud rate to the Master not take part
in communications, they can also cause communications errors for com-
munications between correctly set nodes.
Mounting
Mount the Unit on DIN 35-mm track using the DIN Track Mounting Hook.
I/O Unit Interface
Connectors
The I/O Unit interface connectors provide I/O Unit interface and allow power to
be supplied to the I/O Units.
A feedback cable must be connected to the right-side connector on the end I/
O Unit (terminator).
One I/O Unit Connecting Cable (cable length 40 mm) is included with each I/O
Unit. One end connector is attached to the Communications Unit. An I/O Unit
Connecting Cable with a cable length of 1 m (GCN1-100) is sold separately.
