Environment
- Workstation
- BACnet devices
Cause
Require information on configuring the workstation Device Node ID and Bacnet Device ID
Resolution
When setting up a workstation two of the parameters to set are the Network ID and the Device Node ID. The Device Node ID corresponds to the BACnet Device ID or BACnet Instance ID in the BACnet protocol.
Essentially the workstation is a BACnet device and when setting the Device Node ID during setup in a BACnet installation, consideration should be taken into account when setting this number.
By default Schneider BACnet controllers use their serial number as the BACnet Device ID but when using 3rd party BACnet controllers, some vendors use different means when setting their BACnet Device ID.
In the past instances have been observed where the workstations Device Node ID is set to 1. If the 3rd parties BACnet Device ID is set to 1 as well, that device will not be found when using find new BACnet devices.
A method of avoiding this is to reserve 191 to 254 for creation of the workstations and set the Device Node ID to the same as the Network ID in the Database Initialization workstation configuration.
Or set the workstations with the Device Node ID's starting with 1, but be aware of this setting when configuring any 3rd party BACnet devices. The Device Node ID/BACnet Device ID must be unique within the BACnet network.
