I need to translate from C to ST following:

ptr = (ACP10PRADR\_typ\*) para\_ptr-\>para.par\_sequ.int\_adr + para\_ptr-\>para.par\_sequ.cnt\_adr;

Should this in ST work:

var

```auto
 ptr : REFERENCE TO ACP10PRADR_typ

```

end\_var;

```auto
ptr ACCESS ADR(servo.para.par_sequ.int_adr + servo.para.par_sequ.cnt_adr);

```

where: “servo.para.par\_sequ.int\_adr” is address of memory buffer allocated with TMP\_alloc. In this memory buffer there is stored array/table of ACP10PRADR\_typ.

Hi @Matjaz_Kopac ,  
para\_ptr-\>para.par\_sequ.int\_adr and para\_ptr-\>para.par\_sequ.cnt\_adr are already 2 addresses so in ST you should not call ADR:

ptr ACCESS (servo.para.par\_sequ.int\_adr + servo.para.par\_sequ.cnt\_adr);

Ciao
