What did make you to add your question to an old existing topic instead creating a new one ? In this way you may never receive an answer as hardly anyone will notice you post.

 Its the very basic and first thing we have tried. String tags not communicate simply as integer or float tags.

In your PLC, do you have a DB designated for HMI communications and data transfer?  I call my DB simply "HMI".  In there, I setup string tags as required for transferring data between PLC/HMI.

In the HMI, I add user input InOut dialog boxes configured as String (or WString I think works as well for certain things, but check the online documentation via F1-Help).  Then it's a matter of pointing the HMI tag to the PLC tag, "HMI".SomeStringTagName, and portal does the rest.
