Chapter Objectives

Sample Network Configuration

The procedures in this chapter will show you how to configure a PanelView Plus terminal to operate as a slave device on a DeviceNet network. A ControlLogix processor with a 1756-DNB DeviceNet module will scan inputs and outputs from the PanelView Plus terminals.
You will learn how to:
configure communications for the PanelView Plus terminal and 1756-DNB module using RSLinx Enterprise software in RSView Studio software.
create a DeviceNet configuration using RSNetWorx for DeviceNet software.
add the DeviceNet module I/O configuration to the ControlLogix tag database using RSLogix 5000 software.
The example configures DeviceNet I/O messaging for a numeric input and numeric output from a PanelView Plus terminal to a 1756-L63 ControlLogix processor, version 15.0.
The PanelView Plus terminal has a network node address of 2.
1756-L63 ControlLogix processor, version 15.0, in slot 0
communicates via the 1756-DNB DeviceNet scanner module at network node address 1 in slot 2.

7. Set the node address to 2, the communication rate to match the
1756-DNB DeviceNet module, and click OK.
The General tab of the DeviceNet Scanner Properties dialog specifies the name, node address, virtual backplane slot, and communication rate of the DeviceNet scanner. The virtual backplane of the PanelView Plus has two slots. Because the terminal resides in slot 0, the DeviceNet scanner is automatically assigned to slot 1.
Publication 2711P-UM004B-EN-P - March 2007
18 Configure the Terminal as a Slave Device
Configure the Slave Inputs and Outputs
You are now ready to configure the slave inputs and outputs in the PanelView Plus terminal. For the example used in this chapter, the 1756-DNB DeviceNet module will scan these inputs and outputs.
One DINT or 4 bytes of input data
One DINT or 4 bytes of output data
IMPORTANT
What differentiates the PanelView Plus terminal as a slave or a scanner is the node you specify for each block of data. The device you configure data for via the I/O Configuration tab is the slave on the network. If the device node matches the node address for the PanelView Plus terminal, then it will operate as a slave. In this example, the node address is 2.
Typically these address blocks will be larger. Minimize the number of address blocks going to a single device.
Definition of Inputs and Outputs
Inputs and outputs are in reference to the PanelView Plus DeviceNet module and correspond to RSNetWorx terminology. In other words, the output of a controller is an input to the PanelView Plus terminal. RSView ME software can read inputs and outputs, but only write to outputs configured in the PanelView Plus terminal.

Chapter Objectives

Configure Communications

The procedures in this chapter build on the example configuration in Chapter 2. In this chapter, you will configure the PanelView Plus as a scanner and the 1756-DNB DeviceNet module as the slave device. The PanelView Plus will scan I/O from the 1756-DNB DeviceNet module.
In this section, you will learn how to:
configure slave input and output data for the 1756-DNB module.
view the structure of the DeviceNet input and output table when
browsing for tags.
copy the RSLinx software configuration to the Target tab.
Configure the Slave Inputs and Outputs
IMPORTANT
To change the scanlist for a device on the network, you must place the device in Idle mode before downloading the changes. For the PanelView Plus, you can load the application but not run it. For the 1756-DNB module, put the ControlLogix processor in Program mode.
To place the device in Idle mode:
For the PanelView Plus, load the application but do not run it.
For the 1756-DNB module, put the ControlLogix 1756-L63
processor in Program mode. This action will clear the run bit Local:2:O.CommandRegister.Run.
You are now ready to configure the slave inputs and outputs in the 1756-DNB module. The PanelView Plus terminal will scan these inputs and outputs.
One DINT or four bytes of input data, starting at byte 4.
One DINT or four bytes of output data, starting at byte 4.

Appendix
A
Restore Configuration to Local Tab
In some cases, it may be necessary to edit an application after the DeviceNet configuration on the Local tab has changed or has been moved to a different computer. The RSLinx Enterprise Local tab configuration stays resident on the desktop computer, regardless of which application is being edited.

Copy Configuration to Local Tab

The following procedure shows how to copy the Target tab configuration for an application to the Local tab to allow for browsing for tags.
IMPORTANT
Make sure that the DeviceNet configuration is saved, make sure the application is backed up using Application Manager.
When you are ready to resume editing, restore the application using the Application Manager. This will create an XML file with the restored I/O configuration. For RSView Studio software, you must complete the following steps.
1. Close RSView Studio software.
2. Disable the RSLinx Enterprise service within the Service Control
Manager (Control Panel>Administrative Tools>Services).
3. Double-click RSLinx Enterprise.
This procedure will overwrite all driver configurations on the Local tab with all of the driver configurations that were on the Target tab when the application was backed up.
4. Make a backup copy of the current RSLinxNG.xml file in
C:\Documents and Settings\All Users\Application Data\Rockwell\RSLinx Enterprise.
5. Rename the Restored_restoredAppNAme_RSLinxNG.xml to
RSLinxNG.xml.
6. Re-enable and restart the RSLinx Enterprise software.
71 Publication 2711P-UM004B-EN-P - March 2007
72 Restore Configuration to Local Tab
To allow browsing for tags, open the Communication Setup under the RSLinx Enterprise tree and apply the shortcut to the DeviceNet driver on the Local tab. If changes are made to the driver configuration on the Local tab, be sure to copy this configuration to the Target tab using the Copy button on the Communication Setup dialog.
