Rockwell Automation 1329I DeviceNet Option FRN 1.XXX - Manual (Page 24)

3-6 Configuring the 1329I Unit and DeviceNet Option
3. Click OK to close the dialog box.
4. Reset the DeviceNet option. The new setting for this parameter will take
effect after a reset. See Resetting the DeviceNet Option in this chapter.
After setting a new node address, you must scan the network. DeviceNet
Manager will then display the new address in the Network Who window
(
Figure 3.7 ) and be able to communicate with the drive so that future
parameter changes take effect.
Setting the Data Rate If switches 7 and 8 on the DeviceNet option are On, the value of Parameter
104 - [NV Baud Rate] determines the data rate at which the unit
communicates on the network. By default, this parameter sets the data rate
to autobaud. If another device on the network is setting a specific DeviceNet
data rate, use autobaud to automatically set the adapter to it. Otherwise, you
must set the parameter to the data rate at which the network is operating.
1. In the Device Configuration - Enhanced Mode dialog box ( Figure 3.8 ),
double-click Parameter 104 - [NV Baud Rate]. The Device
Configuration - Modify Enumerated Parameter dialog box appears.
Figure 3.10 Modifying the Data Rate Parameter
2. Select the data rate at which the network is operating or autobaud, and
then click Save to Device.
3. Click OK to close the dialog box.
4. Reset the DeviceNet option. The new setting for this parameter will take
effect after a reset. See Resetting the DeviceNet Option in this chapter.
The 1329I unit will fault after it is reset because it will not be operating
at the same data rate as other devices (e.g., the computer) on the network.
Clear the fault.
Communications with DeviceNet Manager will be disrupted because the
1329I unit and DeviceNet Manager will not be operating at the same data
rate. Disconnect the software and then reconnect at the new data rate.
