Commands / symbols
The following table provides an overview of the existing ladder diagram symbols
and their equivalent representation in the ‘statement list’ programming language
used for checking purposes. Not all symbols in the ladder diagram column are di-
rectly available to the programmer. A few are available from the user program cre-
ated by the programmer. The description of the symbols available for program cre-
ation and the respective statement list of the timer and functions are provided fol-
lowing this table.
The translation process of the ‘ladder diagram’ programming language to the
‘statement list’ programming language necessary to check the program is de-
scribed in Chapter 6.15.3 / 6-104 using a detailed example.
