PMC_PRFRDDIDO | PROFIBUS

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

Specify the index number for DI/DO address data. (0 - 47)

Pointer to the IODBDIDO structure storing the DI/DO address data.
The IODBDIDO structure is as follows.

typedef struct {
    short          slave_no ;
    short          slot_no ;
    unsigned char  di_size ;
    char           di_type ;
    unsigned short di_addr ;
    unsigned char  do_size ;
    char           do_type ;
    unsigned short do_addr ;
    short          shift;
    unsigned char  module_dlen ;
    char           module_data[128] ;
} IODBDIDO ;

slave_no

The station number of the DP-Slave is stored.(0-125)

In case that the specified index number is final or unsetting, "-1" is stored.

slot_no

The slot number is stored. (0-23)

di_size

The size of area used as buffer for DI data is stored.

di_type

The kind of the PMC address used as a buffer for the DI data is stored with ASCII CODE.

di_addr

The top number of the PMC address used as a buffer for the DI data is stored.

When this data is not set, the "0xFFFF" is stored.

do_size

The size of area used as buffer for DO data is stored.

do_type

The kind of the PMC address used as a buffer for the DO data is stored with ASCII CODE.

do_addr

The top number of the PMC address used as a buffer for the DO data is stored.

When this data is not set, the "0xFFFF" is stored.

shift

The data that indicates if the area whose size is specified by "module_dlen" is newly allocated is stored.

1 (ON)	:	allocated
0 (OFF)	:	not allocated

module_dlen

The data length of "Module" keyword in GSD file is stored. (0 - 128)

module_data

The data of "Module" keyword in GSD file is stored.

The data of the number of bytes returned to above-mentioned module_dlen is effective.
