To bind two Bacnet devices in Honeywell SpyderTool:
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.
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.
AI, BI, AV/BV/MSV(setup as NetworkOutput) can act as source objects to the device.
AV/BV/MSV (setup as NetworkInput) can act as destination objects to the device.
Only the custom Bacnet objects are displayed in the Add Binding dialog box for binding devices. The mandatory and fixed objects are not available for binding.
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.
