OCXcip_GetDeviceIdStatus
Syntax
int OCXcip_GetDeviceIdStatus (OCXHANDLE apihandle,
BYTE *pPathStr,
WORD *status,
WORD timeout);
Parameters
apihandle
handle returned by previous call to OCXcip_Open
pPathStr
path to device being read
status
pointer to location receiving the Identity Object status word
timeout
number of milliseconds to wait for the read to complete
Description
OCXcip_GetDeviceIdStatus retrieves the identity object status word from the
device at the address specified in pPathStr.
apihandle must be a valid handle returned from OCXcip_Open.
status is a pointer to a WORD that will receive the identity status word data. The
following bit masks and bit definitions may be used to decode the status word:
OCX_ID_STATUS_DEVICE_STATUS_Mask
OCX_ID_STATUS_FLASHUPDATE: Flash update in progress
OCX_ID_STATUS_FLASHBAD: Flash is bad
OCX_ID_STATUS_FAULTED: Faulted
OCX_ID_STATUS_RUN: Run mode
OCX_ID_STATUS_PROGRAM: Program mode
OCX_ID_STATUS_FAULT_STATUS_MASK
OCX_ID_STATUS_RCV_MINOR_FAULT: Recoverable minor fault
OCX_ID_STATUS_URCV_MINOR_FAULT: Unrecoverable minor fault
OCX_ID_STATUS_RCV_MAJOR_FAULT: Recoverable major fault
OCX_ID_STATUS_URCV_MAJOR_FAULT: Unrecoverable major fault
Note: The key and controller mode bits are 555x specific
OCX_ID_STATUS_KEY_SWITCH_MASK: Key switch position mask
OCX_ID_STATUS_KEY_RUN: Key switch in run
OCX_ID_STATUS_KEY_PROGRAM: Key switch in program
OCX_ID_STATUS_KEY_REMOTE: Key switch in remote
OCX_ID_STATUS_CNTR_MODE_MASK: Controller mode bit mask
