PBM_RD_SLOTINFO | PROFIBUS

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

The first slot array number that you want to get information

Number of slots that you want to get information

Specifies the pointer to the OUT_PBMSLOTINFO structure to store the DI/DO information.
The OUT_PBMSLOTINFO structure is as follows.
It is necessary to allocate the size of structure specified by the above "number" beforehand.

typedef struct _OUT_PBMSLOTINFO{
    unsigned char   slv_no;
    unsigned char   slt_no;
    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;
    unsigned char   module_type;
    unsigned char   commstat;
    unsigned short  reserved;
} OUT_PBMSLOTINFO;

slv_no

number of slave station

0x00 to0x7d	:	valid slave station
0xff	:	invalid slave station

If a slave station is invalid, following information is invalid.

slt_no

module number of slot

di_size

the size of DI data

do_size

the size of DO data

di_path

PMC path number of DI data

do_path

PMC path number of DO data

di_kind

PMC address of DI data

do_kind

PMC address of DO data

di_top_address

top number of PMC address of DI data

range: depend on the PMC address

do_top_address

top number of PMC address of DO data

range: depend on the PMC address

module_type

type of module

1	:	INPUT only
2	:	OUTPUT only
3	:	INPUT and OUTPUT
4	:	no INPUT and no OUTPUT
200	:	out of size for INPUT/OUTPUT
201	:	violation of PROFIBUS standards
255	:	unsetting

commstat

the state of communication

0x00	:	invalid slave station
0x01	:	valid slave station (communicating)
0x02	:	valid slave station (disconnecting)

reserved
