Object Status
This network variable reports the status for any functional block on a device. It is also used to report
the status of the entire device and all functional blocks on the device. A status update consists of an
object ID (the
object_id field) and multiple status fields. The object ID is the functional block index as
described under nviRequest . If the object ID is zero, the status of the device itself and all functional
blocks on the device is reported. The status fields are one-bit bitfields. The only supported status fields
are the
report_mask , invalid_id , and invalid_request fields; all other status fields are not supported.

invalid_request - Set to one if an unsupported request code is received on the nviRequest input
network variable.

invalid_id - Set to one if a request is received for a functional block index that is not defined in the
device. No further checking of the request code is required when set to one.

report_mask Set to one if an RQ_REPORT_MASK request is received by the nviRequest input
network variable, and the nvoStatus network variable is set to contain the status mask. The status
mask is an nvoStatus value that describes the status bits that are supported beyond the three
mandatory status bits. The status mask consists of all fields in the nvoStatus network variable, with
the exception of the report_mask , invalid_id , and invalid_request fields. A one bit in the mask
means that the functional block may set the corresponding bit in the nvoStatus network variable
when the condition defined for that bit occurs. A zero bit means that the functional block may never
set the bit.
