Adding symbols to the simulation project
The "Add Symbols to Simulation" dialog offers the possibility to maintain the simulation project after changing the original project. Before opening the dialog the TwinCAT Simulation manager scans the original and the simulation PLC project and offers the delta of the symbols inside the left hand side list box ("Original PLC(s)").
With adding the symbols to the right hand side pane ("Simulation PLC") the symbols to add can be selected.
