PMC_PRFRDSLVID | PROFIBUS

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

Specify the slave index number. (0-47)

Pointer to the IODBSLVID structure storing the slave index data.
The IODBSLVID structure is as follows.

typedef struct {
    short          dis_enb ;
    short          slave_no ;
    short          nsl ;
    unsigned char  dgn_size ;
    char           dgn_type ;
    unsigned short dgn_addr ;
} IODBSLVID ;

dis_enb

The state that indicates whether the master communicates with the specified DP-slave is stored.

0	:	DISABLE	Communication disabled
1	:	ENABLE	Communication enabled

slave_no

The station number of the DP-Slave is stored.

When this data is not set, the "-1" is stored.

nsl

The number of I/O module units which are installed in the corresponding slave station is stored.

When this data is not set, the "-1" is stored.

dgn_size

The size of the area where the diagnosis data is read is stored.

dgn_type

The kind of the PMC address used as an area where the diagnosis data is read is stored with ASCII CODE.

dgn_addr

The top number of the PMC address used as an area where the diagnosis data is read is stored.

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