BACnet OPC Server Tutorial:

Step 1 - Configure Port

From the tools menu select Configure Port. The application will default to BACnet/IP configured on network 1. You may need to change the network number to suit your site.

Step 2 - Configure Device

From the tools menu section select Configure Device. The application will default to device instance 0 and is the ID of the BACnet OPC server. This should be changed to a new device instance when used on site. Each device on the BACnet network number needs a unique device instance. The BACnet installer will give you a device instance to use, in this example we will use instance 200. You can leave the other options as their default values.

Step 4 - Browse BACnet Network

You are now ready to Browse the BACnet Network and automatically create OPC Tags, from Edit menu select "Browse BACnet Network" to bring up a list of available BACnet Devices on the Network. You can highlight the devices for which you want OPC Tags created for. The Options Button allows you to select the filter settings which are used when creating OPC Tags. Select OK and the BACnet OPC Server will then build up the OPC Tags for the devices you have selected.

While the BACnet Server is building the OPC Tag list, you will see the following progress bar which indicates the status. It starts by reading the Object List from the device and then it builds up a list of OPC Tags based on the Names of the Objects inside the device. You can Cancel from this operation at any time and the BACnet Server will add the Objects located up to that point. If you Browse a second time, the BACnet Server will start from the last object it was reading.

Step 5 - View the Real Time Data

After the OPC Tags have been built, the explorer will be populated with the OPC Tag list. The OPC Tags are grouped in the same format as the BACnet Network which groups points by Device - Object Type - Object Name. When you navigate to the list of names, the BACnet OPC server will display real time data as shown below.

Step 6 - Save the OPC Tags

After the Tag list has been build, the OPC Tag list should be saved into the database. The BACnet OPC Server uses a CSV file for storing the OPC Tag database, you can save the configuration under a new name name using the File - SaveAs option. The BACnet OPC server is now ready for use and will load in the Saved OPC Tag list the next time it starts.
