PBS_RD_PARAM | PROFIBUS

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

Specifies the pointer to the OUT_PBSPRM structure to store the the acquired parameter.
The OUT_PBSPRM structure is as follows.

typedef struct _OUT_PBSPRM{
    unsigned char       slave_no;
    unsigned char       pad;
    unsigned char       di_size;
    unsigned char       do_size;
    unsigned char       di_path;
    unsigned char       do_path;
    unsigned char       di_kind;
    unsigned char       do_kind;
    unsigned short      di_top_address;
    unsigned short      do_top_address;
} OUT_PBSPRM;
