A POU name is used in the project, which is already used for
a library POU. Rename the POU.
Use command ‘Project’ ‘Rename object’ to rename the POU
in the object organizer, or change the name of the POU in

Take care that there is only one identifier with the given
name in the declaration part of the POU.
A FB instance was used, which needs itself.
Add a valid address after the keyword AT or modify the

Put the declaration to a VAR or VAR_GLOBAL declaration
area.
Modify the address or modify the type of the variable to
which the address is assigned.
The type of this variable cannot be placed on the given

In the definition of the enumeration type an identifier is
missing after the opening bracket or after a comma between
the brackets.
Enumerations can only be initialized with numbers of type
INT.
Check if you have followed the following rules for the
definition of enumeration values:
- Within one enum definition all values have to be unique.
- Within all global enum definitions all values have to be
unique.
- Within all local enum definitions all values have to be
unique
