12.13.36 View as ladder logic
Shortcut: + <2>
This command (category 'FBD / LD / IL') is available, if you currently are working in the
Function Block Diagram (FBD) or Instruction List (IL) view of the POU. It can be used in
offline and online (online not available with the current version) mode.
Notice anyway, that there are some special elements, which cannot get converted and
thus will only be available in the appropriate editor view. Further on some constructs
might not be converted un-ambiguously:
FBD elements which cannot be displayed as LD elements (for example XOR) will be
displayed as FBD boxes within a LD network.
To switch back to the FBD view use command View as function block diagram.
To switch back to the IL view use command View as instruction list .
Attention: A proper conversion presumes syntactically correct code. Otherwise parts
of the implementation can get lost.
Note: Concerning the view options for the components of a LD / FBD network notice
the settings in the 'FBD/LD and IL editor Options'.
12.13.37 View as instruction list
Shortcut: + <3>
This command (category 'FBD / LD / IL') is available if you currently are working in the
Function Block Diagram (FBD) or Ladder (LD) view of the POU. It can be used in offline
and online (online not available with the current version) mode.
The FBD resp. LD networks will be converted to an instruction list.
Note:
Notice for conversions:
There are some elements, which cannot get converted and thus the respective
network will remain in the original editor view. Example: operators CALC, CALCN. In
case of syntax errors also no conversion is possible; a corresponding error message
will be generated.
Some constructs might not be convertible unambiguously and thus will be
"normalized" after a conversion from IL to FBD/LD and back. This concerns negations
and explicit/implicit assignment of function block in- and outputs.
To switch back to the FBD view use command View as function block diagram.
To switch back to the LD view use command View as ladder logic .
Attention: A proper conversion presumes syntactically correct code. Otherwise parts
of the implementation can get lost.
Note: Concerning the view options for the components of an Instruction List notice
the settings in the FBD/LD and IL editor options'.
