The Visual BACnet Device Browser will alert users when new devices are added to the BACnet network. All devices will automatically be marked as "unknown." Users can manually flag those devices as "approved" or "unapproved."
Marking devices as "approved" indicates to fellow users on your site that the device should be on the system and is not rogue or malicious. Marking devices as "approved" or "unapproved" does not affect their ability to communicate on the network, but helps users organize and track their assets.
When you flag a device as "unapproved," you should investigate further to find where this device is, who added it to the network, and how it is communicating on the system. Leave it as "unapproved" until you've confirmed if it's a legitimate new addition, or a rogue or malicious device.
Tip: Use the "approved" and "unapproved" field as part of your installation process! An "approved" device should have a unique device ID and IP address assigned within the network of the Site node tree, or within the network of the single monitoring node if it isn’t part of a Site tree. Visual BACnet Site Monitoring will aggregate the ID, IP address, and vendor information to the Site level when this device is added to the Device Browser. When you've completed every step in your implementation process, flagging the device as "approved" is your check to mark that installation as done!
