Hi,
Here're the things I would check.. in that sequence:
1. Having configured the RSLinx OPC Server, do I see the items in Server Explorer. (Note that here we do not even use LV-DSC; we're only checking if the RSLinx OPC Server has been correctly configured).
2. Once we succesfully can read/write the items from the ServerExplorer utility, launch LV-DSC and create Tags in the TCE. You must be able to browse the RSLinx OPC Server in the TCE to generate tags.
3. Once you have the Tags, launch the Tag Monitor utility and make sure you can read/write to these Tags. (Note that here we are using the DSC Engine, but not the HMI Wizard yet).
4. Now, finally, you invoke the HMI Wizard on a Control/Indicator and connect to the
relevant tag. Run the VI again and check if the value updates in the control.
The DataSocket URL stuff dropped by the HMI Wizard is for internal conversion of protocols. You do not need to do anything special about this.
For troubleshooting each step above, there are different things you can try. For instance, if you can see the Items update in Server Explorer but not in Tag Monitor, you probably need to lower the update deadband. If you see the tags update in Tag Monitor but not in your Wizard-generated VI code, you may want to create a test VI using the Rad Tag and Write Tag VI, bypassing the Wizard.
Hope this helps,
Khalid
