Local In the fields class and type the default settings were simply adopted. We just
want to point out that the variables in the example were declared locally. That
means that the declaration only applies to the POU in which it is located, here in
the program And. If a variable, e.g. an input, is to be used in several POUs it is
easier to declare it as a global variable. Using the selection field type helps to
avoid invalid declarations. During declaration the 'Autodeclaration' option also
helps to prevent syntax errors which may cause confusing error messages in
compilation, especially at the beginning.
This completes our little POU.
