Config Variable With Incomplete Address
Variables defined in a VAR_CONFIG
block, i.e. config variables, must specify a complete address.
Erroneous code example:
VAR_CONFIG
main.foo.bar AT %I* : BOOL;
END_VAR
In this example main.foo.bar
has specified a placeholder hardware address.
For the example to be considered valid, a specific address such as %IX1.0
should have been declared.
