Plant SCADA link variables and tags with unity Pro (Control Expert)

does anyone know how to link variable between M340 CPU and Plant SCADA including UDT & DDT. I have created a PLC program with defined data types (structures) and when I link my project Plant SCADA does not see these variables. Is it available or I will have to modify my PLC?

Latest OFS for Plant SCADA doesn't require the presence of the license.
