I have a project in which I work with CompactLogix linked at 24 flex I/O by devicenet, the problem is when I generated all tags from Rsnetworkx using tag generator, I don't know what is the next step.
what I used to read Tags in Rslogix5000? MSG or they are already away when I used tag generator.(I work in offline mode)

thanks for your help
 
Data is exchanged with the CompactLogix via the I/O image of the 1769-SDN Scanner module. The data that goes into each memory location is determined by the Scanlist Data Mapping, which is done in RSNetworx for DeviceNet.

Once your data is mapped into the scanner, the DeviceNet Tag Generator creates user-defined datatypes based on the I/O modules in the RSNetworx project, and creates both tags and the logic to get data between the I/O image and those tags.

You do not need to use any MSG instructions to handle this data. You should just be able to put the scanner into RUN mode with the .RUN bit in the Command Word and start using the I/O.

Everything depends on having a proper Scanlist. FLEX I/O is fairly challenging to work with on DeviceNet, so you should focus on understanding how the modules are configured in RSNetworx first.
