4.3. Object status variables
4.3.1. nviRequest (Object Request)
SNVT type: SNVT_obj_request (92)
This is the variable to request the node status response. LONWORKS 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.
4.3.2. nvoStatus (Object Status)
SNVT type: SNVT_obj_status (93)
This is the variable to inform the object status. LONWORKS option unit supports some status shown in
the table below.
Bit Request Description

4.6.10. nvoDrvAlarm (Alarm)
SNVT type: SNVT_switch (95)
It provides the inverter fault.
- Status nvoDrvAlarm
value state Status
0% 0 No fault
Fault code*1 1 Fault
*1: Lower 7bits show the inverter fault code. As the fault code may be indicated in 0.5% unit on
network tool, correct value is twice value as it. 8th bit shows the communication error between
the inverter and the option (including RS485 port connection, “1” means abnormal.).
<Example>
In under emergency stop, the fault code of the inverter is set to 0x11 (the method of decimal
numeral 17). It is displayed as 17x0.5%=8.5%. When communication is in abnormal state, it
is set to 128 because the 8th bit is set to 1, and its value is set to 128x0.5%=64%.
