PBM_RD_SUBPRM | PROFIBUS

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

Specifies the kind of the setting assistant parameter.
slvslt_ind structure is used according to the kind of parameter.

(note) about usage of slvslt_ind

Specifies the pointer to the T_SLVSLT_IND structure.
The T_SLVSLT_IND structure is as follows. When the slave station or slot module is set to type, this structure is used.

typedef struct _T_SLVSLT_IND{
    unsigned char   slv_no;
    unsigned char   slt_no;
} T_SLVSLT_IND;

slv_no

Station number of slave

range: from 0 to 125

slt_no

Slot number

range: from 0 to 127

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

typedef struct _OUT_PBMSUBPRM{
    union {
        unsigned char  max_slv_num;
        unsigned char  max_slt_num;
        unsigned char  enb_slv_num;
        unsigned char  total_slts;
        unsigned char  shift_mode_stat;
        T_MAXMODLENPRM max_mod_len_prm;
    } subprm;
} OUT_PBMSUBPRM;

typedef struct _T_MAXMODLENPRM{
    unsigned char   slv_no;
    unsigned char   slt_no;
    unsigned char   max_mod_len;
    unsigned char   pad;
} T_MAXMODLENPRM;
