Linking signals correctly
To operate the controller or to output status messages, you can freely link internal digital
and analog signals to sources and targets.
You can avoid faults if you observe the following:
ƒ Always select the source from the target:
– Ask yourself, where the signal comes from.
– Like this, you can easily find the correct entry for the corresponding code.
ƒ A source can have several targets:
– Thus, when a target is assigned to a source, undesirable or duplicate assignments
that are mutually exclusive may occur.
– Ensure that a source is only linked to the desired targets.
ƒ A target can only have one source.
)
Note!
The default setting defines the signals for the most frequently used function
modules of the standard I/O and application I/O. If the default setting is
changed, all unused signals must be set to FIXED−FREE in order to ensure
trouble−free operation.
Brief overview of the code table and signal flow diagrams
The code table provides a list of all functions including brief explanations in numerically
ascending order. (

The signal flow diagrams show the way the codes are integrated in the internal signal
processing structure. (
