Logix5000 and ControlNet

Can anyone help please, I get the following message when I save my ControlLogix project:

“Warning: Associated RSNetWorx file name of device conflicts with associated file name of device at same node and slot in ControlNet project file."

I have a 1756-CNB and a 1756-DNB in the project both networks are working.

There is a topic on the Rockwell site - but it is locked #32891.

Any help would be most appreciated.

Thanks .... Kev

Hi Kev,

The simplest fix is delete the associated filename within the DNB and CNB modules within RSLogix5000. It is only a software link between the Logix file and the Networx files, and doesn't really do much with the programming or configuration. Also is annoying when the files are transferred to different PC's and the warning pops up. Otherwise change the filename.

Trevor.

Kevin,

Here is the full article from the Rockwell web-site.

------------------------------------

Warning messages when multiple ControlNet Bridge modules have associated RSNetWorx files in RSLogix5000.

Associated ControlNet files are stored in two different locations when using ControlLogix processors.

A file name is stored in the RSLogix5000 .ACD project file and in the RSNetWorx for ControlNet .XC project file.

The file association in RSLogix5000 Software is used to launch RSNetworx for ControlNet from within RSLogix5000.

The file association in RSNetworx allows the user to jump between different ControlNet .XC project files. It is this feature that is addressed in this Technote. This fila association is assigned for 'offlink' CNB modules.

Offlink is meant to mean a CNB module in a rack other than the module that connects the rack to the local ControlNet network.

If the files specified in those two locations point to different file names, warning messages are generated when RSNetWorx for ControlNet is launched from RSLogix5000.

In the following project, there are 3 1756-CNB/D modules, each with it’s own ControlNet network, meaning each will have a different associated .XC file.

This is an example of the messages that are encountered:
“Merging module at node 1, slot 4: Network1”
“Warning: Associated RSNetWorx file name of device conflicts with associated file name of device at same node and slot in ControlNet project file.”
“Merging module at node 1, slot 5: Network2”
“Warning: Associated RSNetWorx file name of device conflicts with associated file name of device at same node and slot in ControlNet project file.”

This image shows the 1756-CNB modules in the I/O tree and the associated file assignments in the module properties:

This image shows the rack in this example ControlNet:

This image shows the properties of the 1756-CNB/D module from RSNetWorx for ControlNet:

These are the steps required to view and/or change the file association in RSNetWorx for ControlNet:
1) Open the appropriate .XC file.
· Enable Edits.
· Right click on the CNB in Slot 5. (Note: This is not the CNB module that is connected to the local ControlNet)
· Go to Properties.
· Select Device Bridging tab.
· Select the same file as has been selected for this module in RSLogix5000 using the "Set Association" button.
· Apply these changes.

· Repeat these same steps for all other modules in this RSNetWorx for ControlNet project.
(1756-CNB modules that appear in the 1756 Chassis that are present in separate ControlNet networks.)

2) Save the .XC file.

3) Repeat these same steps for all other ControlNet networks in the RSLogix5000 project.

Here is where the associated file that is specified in the RSNetworx .XC file is used to 'Jump to the Associated Network'.

NOTE: You select this menu by Right-Clicking on the 'Offlink' 1756-CNB module.

Summary: Associated ControlNet files are stored in two different locations when using ControlLogix processors.

A file name is stored in the RSLogix5000 .ACD project file and in the RSNetWorx for ControlNet .XC project file.

If the files specified in those two locations point to different file names, warning messages are generated when RSNetWorx for ControlNet is launched from RSLogix5000.

The file association in RSNetworx allows the user to jump between different ControlNet .XC project files. It is this feature that is addressed in this Technote. This fila association is assigned for 'offlink' CNB modules.

Offlink is meant to mean a CNB module in a rack other than the module that connects the rack to the local ControlNet network.
