Binding Bacnet Devices

To bind two Bacnet devices in Honeywell SpyderTool:

  1. Right-click Bacnet Network in the Nav palette and select Views > Wiresheet. All devices on the Bacnet Network are displayed as containers on the wiresheet.
  2. Right-click the source device container and select Link Mark.
  3. Right-click the destination device container and select Link To. The Add Binding dialog box appears.
  4. Click the Object of the source controller you want to link. The pane showing the destination objects highlights the objects with which you can bind the source object.
  5. Select the Object from the destination device pane to which you want to link the source object.

Note: The Object Properties of the source device shows Present Value. This implies that the present value of the object input or object output is taken as input to the control logic.
The Object Properties of the destination device shows Present Value for all objects except AO and BO. When an AO or BO object is selected as a destination object, Object Properties displays the priority array index from 1 to 16. You can set the priority value for the destination object.
If an AO and BO object is set as the source objects, then their present value is taken as input to drive the logic.
AO and BO object types can act as both source and target.

  1. Click OK. A link appears on the wiresheet between the source and destination controllers.
  2. Right-click Bacnet Network in the Nav palette and select Views > Bacnet Link Manager. A row providing the link details appears.
  3. Select the row and click Bind to complete binding Objects between a source and destination controller.

Note: Binding cannot be done if both source and destination devices are third party Bacnet devices. Atleast one of them must be a Spyder device.

Unlike LON, the objects will not be present under the device level until you click Generate Network Objects on the BacnetSpyder device.This option creates a BacnetObjectReferences for network objects in the Control Program.

When a new network object is added, perform Generate Network Objects so that the corresponding BacnetObjectReference is added at the BacnetSpyder device level.

When you perform operations such as delete/modify Network Objects in the Control Program, BacnetObjectReferences are automatically updated.

Generate Network Objects option recreates the BacnetObjectReferences under the device as per the Bacnet Objects under Control Program of that device. You do not have to be online for the Spyder device to use this option. You can set up offline Bacnet data sharing links involving Spyder devices and bind the devices when the Spyder devices are online. This feature is of useful for offline engineering.
