What Can The Tool Do?

The first thing I found was the ease of use of this program. In order to scan the network all I needed was one BBMD. First, use an IoT search engines to find a publicly exposed BBMD (there are literally thousands of exposed BBMD’s worldwide). The image below shows the results of taking one of these IP’s and entering it into the tool. As you can see from the one found using the IoT search engines, the scan revealed even more IP’s that are not listed on the IoT search engine. In addition to finding other BACNet IP devices, it discovered MSTP (serial communicating devices) BACNet devices as well. There can be hundreds of devices attached to the system and thousands of points underneath the devices that can be controlled with this tool.

All the devices and points can be accessed without using a user/password.

By clicking on device in the top left window (image below) the device’s associated points will be displayed in the bottom left window. These points can be dragged into the middle window and their value and status are displayed along with device ID, object ID, name, and update time.

Clicking on a point in the bottom left window will display its properties in the window on the far right.

You have full control of the properties to be able to write to it.

The point property window allows for editing of the point parameters. In the image below the call-outs show what is editable (in black) and parameters that could take the point offline (in red). Depending on the point type, command and control of these points/devices could lock operators out, change VFD speeds to an unsafe level, modify setpoints, etc.
