This is the variable to request the node status response. L
ON
W
ORKS
option unit supports some requests
shown in the table below.
Value Request
Description
0
RQ_NORMAL
Just report “mvoStatus”. The state of the object is unchanged.
2
RQ_UPDATE_STATUS
It requests the status of the object to be sent to the “nvoStatus”
output network variable. The state of the object is unchanged.
RQ_REPORT_MASK
It requests a status mask reporting the status bits that are
supported by the object to be sent to the “nvoStatus”
output
network variable. A one bit in the status mask means that the
device may set the corresponding bit in the object status when
the condition defined for that bit occurs.
10 RQ_CLEAR_ALARM
It requests the alarm state of the object to be cleared. If any
alarm conditions are still present for the object, the alarms are
reported again as they are detected.
N.B.: This option does not use the object ID, so it works according to the request in spite of received
value of object ID.
N.B.: In case that receiving the request other than above, this option unit sets “1” to
“invalid_request” bit of “nvoStatus” output network variable.
