PMC_PRFWRDIDO | PROFIBUS

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

Specify the index number for DI/DO address data. (0 - 47)
When "-1" is specified, slave_no and slot_no in the IODBDIDO structure are effective. (When the data of specified slave_no and slot_no exist, the following data is updated.)

Pointer to the IODBDIDO structure including 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

Specify the slave station number of the DP-Slave. (0-125) (It is effective at only idx=-1.)

slot_no

Specify the slot number. (0-23) (It is effective at only idx=-1.)

di_size

Specify the size of area used as buffer for DI data. (0-244)

di_type

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

di_addr

Specify the top number of the PMC address used as a buffer for the DI data.

When you want to initialize this data, please set "0xFFFF".

do_size

Specify the size of area used as buffer for DO data. (0-244)

do_type

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

do_addr

Specify the top number of the PMC address used as a buffer for the DO data.

When you want to initialize this data, please set "0xFFFF".

shift

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

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

module_dlen

Specify the data length of "Module" keyword in GSD file. (0 - 128)

* Further, as for one slave, the total of every module size should be within 128 bytes.

module_data

Sets the data for "Module" keyword in GSD file.

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