7.3. Hilscher Fieldbus CIF Card Status API

The status of the Hilscher Fieldbus Card is read from buffer 2 with a length of 64, using the function DR_ApReadStatus, as follows:

    DR_ApReadStatus (dev, 2, 0, 64, &status, &error)

The offset and length are ignored. Status is a structure of type cif_ApState_t (see the file cif_api.h) and is defined as follows:

    typedef struct {
        unsigned char	global_bits;
        unsigned char	bus_status;
        unsigned char	err_rem_addr;
        unsigned char	err_rem_event;
        unsigned char	reserved[28];
        unsigned char	state [16];
        unsigned char	diag [16];
    } cif_ApState_t;
