Chapter 1 Install a 1756 DeviceNet Communication Module
5. From the Data Rate pull-down menu, choose the communication (data)
rate.
6. Click Apply.
7. Cycle power to the 1756-DNB scanner module.
Set the Node Address
The 1756-DNB scanner module supports DeviceNet node addresses 00…63.
The factory default setting is node address 63.
Change the node address by setting the rotary switches or commissioning the
1756-DNB scanner module in RSNetWorx for DeviceNet software.
Use the switches to select any network address from 00…63. When the switches
are set outside of this range (except for 888), you can configure the node address
with RSNetWorx for DeviceNet software. When all 3 switches are set to 8, the
1756-DNB scanner module will reset to factory default settings at powerup.
Figure 2 - Node Address Rotary Switch
Set the Rotary Switches
Use the node address rotary switches to change the DeviceNet node address for
the 1756-DNB scanner module.
1. If the module is removed from the chassis, be sure that power is removed or
the area is nonhazardous before proceeding.
2. Move the rotary switches to the desired position.
3. If necessary, reinstall the module into the chassis.
Table 2 - Switch Settings
Switch Setting Node Address
0…63 The DeviceNet node address is 00…63.
888 When all 3 switches are set to 8, this resets the 1756-DNB scanner module
to factory default settings. Do not use for normal operation.
All other values Select the node address with RSNetWorx for DeviceNet software.
