    I was looking at the possibility of creating nested data types in CoDeSys 2.3 (as in Simatic). Is this possible? Something like the below:

    TYPE Test :

    STRUCT

    Real1: REAL;

Real2: REAL;

RealSet: STRUCT

    Real3; REAL;

    Real4: REAL;

END_STRUCT;

    END_STRUCT

    END_TYPE

    Hi,

    you can do this, but first you have to declare the "inner" type separately. 

    TYPE TRealSet: STRUCT
Real3; REAL;
Real4: REAL;
END_STRUCT
END_TYPE

    This you can use now as follows:

    TYPE Test :
STRUCT
Real1: REAL;
Real2: REAL;
RealSet: TRealSet;
END_STRUCT
END_TYPE
