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.
Code table and signal flow diagram as a quick overview
In the code table all functions are numerically listed in the form of a "reference book" with
short explanations. (
The signal flow diagram shows in which way the most important codes are integrated in
the internal signal processing. (
