PMC_PRFWRSLVADDR | 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 ;

slave_no

Specify the station number of the DP-Slave.(0-125)

In case of 6558 system, the address allocation data can be initialized by specifying "-1".

di_size

Specify the size of area used as buffer of DI data.

6557 Series	Version 01-07	:	(1-32)
6557 Series	Version 09 or later	:	(0-244)

di_type

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

di_addr

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

do_size

Specify the size of area used as buffer of DO data.

6557 Series	Version 01-07	:	(1-32)
6557 Series	Version 09 or later	:	(0-244)

do_type

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

do_addr

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

reserve

not used

* 6557 Series Version 09 or later:

Set parameter di_size and do_size so that the total of the two parameter lengths does not exceed 244.
