SCL error function(SFC14) not defined

Dear experts

I'm writing a program in SCL where I have to read input value's of a multimeter over profibus. I can only read the first input adres (256) and from there I have to put the other input values in a db.

For this i'm using SFC14 "DPRD_DAT".

When trying to compile my program i get the error:  "function not defined." So it's telling me that it doesn't recognise the system function  14. I have tripple checked that SFC14 is defined in the symbol table as  DPRD_DAT.

Using SFC14 in STL in the ob1 block is no problem and works correctly.

But for my assignment it has to be all written in the same function in SCL.

My code in SCL:

VAR_INPUT
input           : INT;
END_VAR

VAR_TEMP

ErrCode                   :   INT;

END_VAR

errcode := DPRD_DAT (LADDR := INT_TO_WORD(input),RECORD := "Lovato_Multimeter".Adres);

Any idea's?

Thanks in advance!

Hello

I have attached the object properties of my CPU 318-2.

It says it has firmware V3.0

To be more specific in the module information: i find firmware V3.5.4

Also i'm not sure what MLFB stands for?

Hi,

i have no error with this code and PLC here with Step7 V5.6.

Can you attach the complete exported SCLSource?

Regards

Christoph

Hello

Sure here you go. Everything else compiles just fine for me except this.
