ANSWER
By default, TIA portal uses symbolic names and no more the Tag addressing. Here are the steps to disable the so called "Optimized access" of your data block and get the tag addresses (ex : DB601.DBD0) you can use in your Flexy configuration.
Step 1 : Access the properties of your data block
Step 2 : Disable the option "Optimized block access"
The Datablock offsets will then appear allowing you to compute the unique register address. (Ex : DB1.DBD0)
Step 3 : Download the program to your PLC
