To make the configuration of BACnet devices and their objects more easier, a tool called BACnet Explorer is provided. Starting with BMS Platform and MP Server version R2 Build 2068, this tool can be used to discover BACnet devices and their objects online or BACnet EDE files can be imported.

This tool is started from the NETx BMS Studio while the NETx BMS Core Server is stopped. To start the BACnet Explorer, shutdown shut down the NETx BMS Core Server and select the menu item BACnet / Start Explorer ...

...

Acknowledge the warning to get to the main window of the online discovery. Afterwards, select the local IP address that shall be used to communication communicate with the BACnet network. Then press the scan button (if required you can limit the search by entering a minimum and maximum device ID):

...

After a few seconds, all available BACnet devices (IP and non-IP ones) will be listed):

...

As nextNext, select the devices and objects that you want to integrate. After selecting a device, the BACnet Explorer will search for all objects that are available within the device and which are supported by the NETx BMS Core Server.

Since the EDE files do not contain the address information i.e. IP address of IP address or link layer address of non-IP devices, the address information must be added in this step. For each device, click on the … button and add the address information. After press next to get to the window where all new objects are listed:

Starting the Core Server

Start the Core Server and open an Item Tree. All BACnet devices and objects are found under the branch NETx\XIO\BACnet. Each device has one entry within the Item Tree. Below this entry a GATEWAY item shows the connection state of the BACnet device. In addition, all selected objects are listed. As defined by the BACnet standard some BACnet objects are read-only (e.g Binary Input, Analog Input, ...) and some are also writable (e.g. Binary Output, Analog Output, ...). Input objects have only one item which shows the current Present Value of the BACnet object. Output objects have in addition for each used BACnet priority one Write Item to send a write command with the given priority and one Reset Item to reset the given priority. The NETx BMS Server supports multiple priorities at the same time. The following figure shows an example.
