Once the installation of the BACnet OPC Server is complete, you will need to create an NCL (Node Control List) file to upload into the Web services Gateway.

Execute the “BACrestcfg.exe” which is located in the folder named “BACrestCfg” to create the NCL file. In order to create the NCL file we would need to be connected to a BACnet network with devices. If you do not have a real BACnet network i.e. working BACnet devices, you could start a simulator device (a software which upon invoking will mimic a real BACnet device) by going to Start | Programs | BACnet OPC Server | Simulator – BACnet Device Good.

Once you are sure about being connected to the BACnet network (or have started the simulation program), start the BACrestcfg.exe by double clicking on it. Once the program opens, click on the “Find Devices” button. This action will result in the discovery of all the BACnet devices on your network. Once you have been able to discover devices, (these are exhibited / displayed on the top half of the window), click on one of the devices (single click is enough). Clicking on the device will further discover the objects of that device and the results are displayed in the lower half of the window. Once you have looked through the object list in the lower window, double click on the object that you would like to map to the Web Services Gateway. Double clicking on the Object will open up a window “Select Properties”. Please select the properties that you would like to have for the object followed by clicking on OK. Once you have worked with all the devices and objects, you are ready to create the NCL File.

Clicking on the “Build NCL Records” button will help create the NCL file. Once this button is clicked, complete the necessary information and click on “Save to NCL File”. This will help you create a new NCL File. Clicking on “ADD to NCL File” will allow you to add new points to an already existing NCL File.
