4-6 Configuring the DeviceNet Network
Setting the 1747-SDN Node Address
Once the devices are uploaded, their node addresses appear to the
right of their icons. For the example application, the 1747-SDN
scanner module should have a node address of “0” (or “00”). If you
need to change a module’s node address, use the following
procedure.
If “00” appears to the right of the 1747-SDN icon and you do not need
to change the node address or baud rate of any device, skip the
remainder of this section and go to “Configuring the I/O Devices” on
page 4-9.
TIP
RSNetWorx for DeviceNet performs a one-shot
browse when you go online or choose the browse
feature. The software will poll for devices one time
and display the results. If a node which was online
later goes offline, there will be no “live” indication in
RSNetWorx. You must manually perform a browse to
detect the missing node.
To manually perform the browse, press the
button.
TIP
If RSNetWorx fails to find a device, check the
physical connection to the device. If the physical
connection is intact, verify that the device’s baud rate
is the same as the 1770-KFD driver’s.
TIP
You can use this procedure to change the node
address of other devices on the network (e.g., the
Photoeye). You can also change the network data
rate (baud rate) of some devices. Power must be
cycled for baud rate changes to take effect.
IMPORTANT
The network must not be active when performing
node commissioning on the 1747-SDN module. Make
sure the processor is in Program mode.
(Note that this applies only to the 1747-SDN. You
may commission other devices with the processor in
Run mode.)
