I would like to know how I can add symbols of Variable table, when I want to simulate because it's very useful when our program has many variable.
Since when it is absolute, it is very difficult to remember that it is each input and output address of the PLC. And it is better to see it symbolically.
when I was use Step 7, I remember that only in PLCSIM i was going on tools and then option and chose the option of assigning symbols. Now I try to do same in Tia Portal but does't work.
