PBM_RD_NODEINFO | PROFIBUS

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

The first slave number to want to get information

Number of slaves in which you want to get information

Specifies the pointer to the OUT_PBMNODEINFO structure to store the slave information.
The OUT_PBMNODEINFO structure is as follows.
It is necessary to allocate the size of structure specified by the above "number" beforehand.

typedef struct _OUT_PBMNODEINFO{
    unsigned char   slv_no;
    unsigned char   commstat;
    unsigned char   status1;
    unsigned char   status2;
    unsigned char   status3;
    unsigned char   master;
    unsigned short  ident;
} OUT_PBMNODEINFO;

slv_no

slave station (when commstat is equal to 0xff, this is master station)

range: 0 to 125

commstat

the state of communication

0x00	:	invalid slave station
0x01	:	valid slave station (communicating)
0x02	:	valid slave station (disconnecting)
0xff	:	master station (self-node)

status1

STATION STATUS1 of dignosis data

status2

STATION STATUS2 of dignosis data

status3

STATION STATUS3 of dignosis data

master

master station that sets parameter of slave station
When the master station does not set the parameter, 255 is stored.

ident

identification number of slave station
