Hello comrades.

Im commenting up a program because its completely empty from comments. We dont have the original file so thats why im commenting the whole program.

Im putting the wire names in symbols and the use of the the wire in the comment

Why am i not able to only put in a comment without putting in a symbol in Simatic manager?

If a symbol is neccesary what should a memory bit be called when i feel like symbols are made for wire name's? Dont know if this makes sense.

Simatic Manager V 5.6
