This is actually possible in V18 Update 5 and V19 for Unified Panels. With some limitations and caveats. Specifically, you need to target a specific ladder section.

The solution uses a poorly documented script function that has now been removed from the documentation for V19.

History is:

• V18 Update 5 introduces it with a disclaimer
  • Works in both simulated and physical panels (MTP2200)
• V19 partially rolls it back
  • No longer listed in documented functions
  • Doesn't work in simulation
  • Works as per V18 in physical panel with V19 firmware image

In both cases there doesn't seem to be a need for ProDiag as there is nothing configured directly in TIA Portal.

Prerequisites are:

• WinCC Unified RT  -> Runtime Settings -> Process Diagnostics
  
• ProDiagOB in PLC Program Blocks as per Graph viewer usage
• Name of the PLC (PLC_1)
• Name of the FB containing the ladder logic (EM23_00_Main)
• A static bool defined in the same FB (#Failsafe_Diagnostics)
• Add the static bool to the right of the logic you need to view
• Call the OpenProDiagDetailsByAssignment system function on HMI

Script to display ladder only in a code viewer control:

 

HMIRuntime.UI.ProDiag.SysFct.OpenProDiagDetailsByAssignment("PLC_1", "EM23_00_Main", "#Failsafe_Diagnostics", "CodeViewer");

 

I've attached the configured ladder FB in TIA Portal and then the resulting view on the physical panel.

Split from is it possible to visualize PLC code display without Graph mode?.
