BACnet OPC Client 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 Client. 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 3 - Automatic Object Creation

You are now ready to create internal BACnet Objects which will be updated with real time data from an OPC Server, from the Tools menu select "Automatic Object Creation" to bring up a list of available OPC Servers on the network. Select an OPC Server from the list and then select OK. The application will attempt to read all of the OPC Tags within the OPC server and map the Tags to BACnet internal objects. The Datatype of the OPC Tag is used to determine the type of BACnet Object to use.

Step 4 - View the Real Time Data

After the BACnet Internal Objects have been built, the explorer will be populated with the OPC Tag list. The BACnet Internal Objects are grouped in the same format as the OPC Server. When you navigate to the list of names, the BACnet OPC Client will display real time data as shown below.

Step 5 - Save the OPC Tags

After the Tag list has been build, the OPC Tag list should be saved into the database. The BACnet OPC Client 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.
