Important User Information

Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://literature.rockwellautomation.com) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment.

The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the examples and diagrams.

Set the Communication Rate

The 1756-DNB scanner module supports the following DeviceNet network communication rates:

•125 Kbps

•250 Kbps

•500 Kbps

The factory default setting is 125 Kbps.

ATTENTION			Do not change the communication rate on an active network. Unpredictable
			operation may result. In addition, the new communication rate does not take
			effect until you cycle power to the 1756-DNB scanner module.

Change the communication rate by setting the rotary switch or commissioning the 1756-DNB scanner module in RSNetWorx for DeviceNet software.

Use the switch to select a specific communication rate. When the switch is set to 3...9 (except for 888), you can configure the communication rate with RSNetWorx for DeviceNet software. When all three switches are set to 8, the 1756-DNB scanner module will reset to factory default settings at powerup.

See Restore the Factory Default Settings on page 15 for more information. See the following table for switch settings.

Set the Rotary Switch

Use the communication (data) rate rotary switch to change the communication rate.

TIP	For ease of access, remove the module from the chassis before proceeding.

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 switch to the desired position.

3.If necessary, reinstall the module into the chassis.

Use RSNetWorx for DeviceNet Software

Follow this procedure to use RSNetWorx for DeviceNet software to set the communication rate.

For more information, refer to the DeviceNet Modules in Logix5000 Control Systems User Manual, publication DNET-UM004.

1.In RSNetWorx for DeviceNet software, select the 1756-DNB scanner module.

2.Select Tools and Node Commissioning.

3.Browse to the DeviceNet network for the 1756-DNB scanner module you want to commission.

4.Select the 1756-DNB scanner module you want to commission.

5.In the Data Rate field, select 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 through 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 three switches are set to 8, the 1756-DNB scanner module will reset to factory default settings at powerup. See Restore the Factory Default Settings on page 15 for more information.

Restore the Factory Default Settings

The out-of-box reset will clear the scanlist (including ADR configuration recovery files) and return all software setting attributes to their default values.

Follow this procedure to restore the factory default communication rate and node address.

1. Set the switches to 888.

IMPORTANT	Do not use the 888 switch setting during normal module operation.

2.Restore power to the module.

When the out-of-box reset is complete, the alphanumeric display repeatedly scrolls the message Reset Complete - Change Switch Settings. During this time, the module does not respond to communication from any port (including the backplane, DeviceNet connector, or USB port).

3.After the module resets, perform the following steps.

a.Set the switches to the desired position.

b.Restore power to the module.
