Message: '<variable>' is not a component of '<structure>'
Possible error cause: Component access with "." to a variable that is not a structured value or does not exist as a component of the structure.
Error correction: Access a defined component, or change the definition of the component in the data type. The input assistance "List components" provides all valid access to this position.
Example of the error:
TYPE DUT: STRUCT x, y : INT; END_STRUCT END_TYPE PROGRAM PLC_PRG VAR test1 : DUT; test2 : INT; END_VAR test2 := test1.z; --> C0032: Type 'Unknown type: 'test1.z'' cannot be converted to type 'INT' --> C0004: 'z' is to a component of 'DUT'
