PMC_PRFRDSLVADDR | PROFIBUS

Specify the library handle. See "Library handle" for details.

Pointer to the IODBSLVADR structure including the address allocation. The IODBSLVADR structure is as follows.

typedef struct {
    char           slave_no ;
    unsigned char  di_size ;
    char           di_type ;
    unsigned short di_addr ;
    unsigned char  do_size ;
    char           do_type ;
    unsigned short do_addr ;
    char           reserve[7] ;
} IODBSLVADR ;
