Show box icon  | The function block symbol is displayed in the block element in the FBD and LD editor. The standard operators also have symbols.  | 
Show operand comment  | TwinCAT displays the comment that you have assigned to a variable in the implementation part. The operand comment only refers to the local usage point of the variable, in contrast to the "symbol comment".  | 
Show symbol comment  | TwinCAT displays the comment that you have assigned to a variable or symbol in the declaration above the variable name. In addition to or instead of the symbol comment, you can also assign a local "operand comment".  | 
Show symbol address  | If an address is assigned to a symbol (variable), this address is displayed above the variable name.  | 
Show network separators  | A dividing line is displayed between the individual networks.  |
