BacnetNetwork "uploadOnStart" property

In AX-3.8 the BacnetNetwork has a new dynamic Boolean property “uploadOnStart”. Note this property appears only after a station with a BacnetNetwork has been started (e.g. not seen in the bacnet palette).

Figure 20. BacnetNetwork “uploadOnStart” property (AX-3.8)

This property determines how newly-added BacnetDevice components under the network are created.

If “uploadOnStart” is true, added BacnetDevice components will have no “skipUpload” slot.

Note the device-level “skipUpload” slot, new in AX-3.7u1, lets you specify to not automatically re-upload all BACnet Device object property values upon each station startup. In AX-3.7u1 (prior to AX-3.8), you have to manually add this Boolean slot to a BacnetDevice, if needed.
If “uploadOnStart” is false, added BacnetDevices are automatically created with a “skipUpload” slot (hidden), with value of true. For devices that do not support message segmentation and/or with small APDU sizes (often MSTP devices), skipping the upload of these properties can greatly speed the startup of the station’s BacnetNetwork, and allow more important and dynamic point values to be read and written without undue delay.

Changing the value of the network’s uploadOnStart property does not affect any BacnetDevice components that already exist in the station. It only determines how newly-added BacnetDevices will be created.
