LonWorks Network Variables
4.2 Supported Input Network Variables
NviObjRequest
Definition Network input SNVT_obj_request nviObjRequest;
Explanation This input is used to enable control commands and updates from the network. The
status of the node is reported in nvoObjStatus.
Valid range:
Object Request Function
RQ_UPDATE_STATUS Updates nvoObjStatus
RQ_CLEAR_STATUS
Clears nvoObjStatus
RQ_CLEAR_ALARM Resets a drive fault
RQ_REPORT_MASK Reports supported requests in nvoObjStatus
RQ_NORMAL The normal request. Sets object to default state
RQ_DISABLE Stops the drive with the selected stop mode and disables
the operation and object
RQ_ENABLE Enables the drive for operation and enables the object
Commands not listed above will be reported as invalid_request in nvoObjStatus.
NviDrvSpeedStpt
Definition Network input SNVT_switch nviDrvSpeedStpt.
Explanation This input network variable provides a low-resolution speed setpoint. It may also
use the receive heartbeat function. The speed setpoint is the result of multiplication
of nviDrvSpeedStpt and nviDrvSpeedScl.
Valid Range:
State Valid Range
0 Stop the drive
1 Start the drive
-1 (0xff) Auto (Invalid)
Value (% Nominal) Internal Value
-100.0% to -0.5% -200 to -1
0.0% 0
0.5% to 100.0% 1 to 200
Default value The default value is AUTO (state = 0xFF). This value will be adopted at power-up.
This network variable input may use the Receive Heartbeat function if the Receive
Heartbeat function is setup for use. The actual value of drive speed also depends
on the setting of nviDrvSpdScl.
