Node Object #0
Node Object contains the functions Object Status/Object Request.
nvoStatus
nviRequest
SNVT_obj_status
Input variable, demands the status of a specific object in the node.
nvoStatus
nvoFileDirectory
Output variable, gives the actual status of a specific object in
SNVT_address
the node.
nvoFileDirectory
Output variable, indicates information in the address area of the
Neuron chip.
Damper Actuator Object #8110
The actuator object shows the functions of the MFT2 actuators on
the L
these objects (one for each MFT(2)/MP actuator, see next page).
nviRelStpt
nvoActualValue
This input variable gives the actuator its reference position or set-
SNVT_lev_percent
point. The variable is normally linked to the output variable of an
HVAC controller.
nvoAbsAngle
nviActuateState
SNVT_angle_deg
This input variable gives the actuator a preset position. Note on
priority: whichever variable, nviActuatState or nviRelStpt, was last
nvoAbsAirFlow
active takes priority.
SNVT_flow
nviManOvrd
These input variables can be used to manually override the actu-
ator into a particular position. If the manual override (nviManOvrd)
is in HVO_OFF status, the network variables nviRelStpt or nvi-
ActuatState are active. The table defined in the functional profile
(#8110) applies to the other statuses.
nviManOvrd
This input variable allows manual overriding of the actuator to
a specific position (the function is only active if preceded by
RQ_OVERRIDE). The function is typically used during the com-
missioning of installations.
nvoActualValue
This output variable shows the actual position of the actuator and
can be used for resetting control circuits or for indicating position.
nvoAbsAngle
This output variable shows the actual angle of rotation of the actu-
ator or damper blade and can be used for indicating position or for
servicing purposes (not for the NMV-D2M or linear actuators).
nvoAbsAirFlow
This output variable shows the actual volumetric flow through the
appropriate box and can be used for control and indicating pur-
poses (MP-VAV only).
Open Loop Sensor Object #1
One sensor can be connected to each MFT(2)/MP actuator. It can
be either a passive resistance-type sensor (Pt1000, Ni1000 or
nvoSensorValue
NTC), an active sensor (e.g. with a DC 0...10 V output) or a swit-
SNVT_xxx
ching contact. The measured sensor values are transferred to the
L
ject is implemented 8 times in the UK24LON unit (see next p. 9).
nvoSensorValue
This output variable shows the actual sensor value. Depending on
the connected sensor, the output variable can be configured via
the sensor plug-in and specifically adapted to the system.
