The Object Outputs (AVO, BVO, MVO) convert input value(s) (Public Variable(s)) into a raw network variable output that is published onto the Bacnet network.
You can add an Object Output from:
To add a new Object Output:
Note: If adding an Object Output to an Application, browse through to the appropriate Application on the Nav palette.
Note: You cannot add an Object Output to a macro.
| Name | Definition |
| Object Name | The name of the Object Output. This field is editable. |
| Object type | Indicates if the object input is of type AV, BV or MSV. This field is non-editable. |
| Object Instance | A unique number that is automatically assigned to the object. This field is editable. If you try replacing the instance value with a value of your choice, the replacement is successful only if the value of your choice is not in use by any other object. |
| Update Interval | The rate at which the controller compares the last value propagated to the network against the current value to determine whether significant change has occurred that warrants the new value to be propagated. Update Interval works with SEN Delta to throttle back the information propagated to the network. Recommended value is 0 second. |
| Sen Delta | The delta value for Significant Event Notification is also known as SEN Delta. The 'presentValue' property of this object is refreshed/updated by the controller when the value changes by the configured SEN Delta. This can be used to tune the controller such that small changes of value are not propagated to the BACnet network . If this object is 'bound' to another controller, then the value is sent on the Bacnet Network to the target controller whenever it changes by an amount exceeding the SEN Delta. A SENDelta of zero means that any change of value is considered significant and is propagated to the network. |
| Object Category | Displays the unit of measurement for the object output. |
| Unit | Displays the engineering unit based on the object category. |
| Sub-Category | Displays the enumeration type for the object inputs. The field Unit is renamed as Sub-Category if the object category selection is unitless. |
| GPU | Set the GPU (guaranteed periodic
update) to either True or False.
|
| Send Heart Beat | The rate at which a Network object value is sent to the network regardless of whether its value has changed or not. The send heart beat must be configured to be equal to or greater than the 'update rate' expected by the target controller. This value should be configured as multiples of 5 seconds only, else tool rounds it off to the nearest multiple of 5 during download. |
To expose the Object Output you have added:
While in the midst of creating an ControlProgram/Application, if you need to quickly add an Object Output, use the Network Outputs item on the Spyder Palette.
Note: You cannot add an Object Output to a macro.
To add an Object Output to an ControlProgram/Application:
Once you have created an Object Output, you can connect an Object Output to an Object Input/Function Block or Physical point by left-clicking on the output of an Object Input/Function Block/Physical point and dragging your mouse to the input of an Object Output.
