Compiler Error C0183

Message: Global scope operation '.' is not valid on expression '<expression>'

Possible error cause: The '.' operator is used to access a global variable. However, at this location it is not followed by a valid IEC identifier, but for example a character such as ";" or a reserved identifier such as FUNCTION, or an operator such as TO_STRING.

Error correction: Use a valid IEC identifier for a global variable.

Example of the error:

PROGRAM MAIN
...

iVar := .FUNCTION;
strVar := .TO_STRING;

Message:

C0183: Global scope operation '.' is not valid on expression '<expression>'

Error correction:

Example: globalValue is declared in a GVL.
PROGRAM MAIN
iVar := .globalValue;
