METHODS OF INTEGRATION WITH BACNETP2


Four Methods of Integration

This short video demonstrates four easy methods available to use BACnetP2.

Configurations

Once you have decided that BACnetP2 is the solution you are looking for, there are a few things to consider. One of the considerations, is what additional hardware, if any, will be required for the particular set up. There are four different configurations that you can use when integrating Siemens P2 to BACnet with BACnetP2. You can connect with P2 over Ethernet, or P2 over RS485, and you can either run BACnetP2 on a dedicated Linux device, or you can run it on a virtual machine.

● Method 1: P2 over ethernet network with a dedicated Linux device running BACnetP2

● Method 2: P2 over ethernet network with a virtual machine running BACnetP2

● Method 3: P2 over RS458 network with a virtual machine running BACnetP2

● Method 4: P2 over RS485 network with a dedicated Linux device running BACnetP2.

All of the methods, except method 2, require you to have some additional hardware. We have made diagrams with system trees, and explanations to help make it clearer.

Method 1: P2 over ethernet network with a dedicated Linux device running BACnetP2

With this method, you have a device running BMS software or a BACnet Browser which connects via BACnet over IP to a dedicated Linux device running BACnetP2. This network is then connected to the rest of the system via P2 over ethernet. The additional hardware needed is the Linux device for running BACnetP2.

Method 2: P2 over ethernet network with a virtual machine running BACnetP2

With this method, you have a device running BMS software or a BACnet Browser, with a virtual machine running BACnetP2. This is connected to the rest of the system via P2 over ethernet. There is no additional hardware needed.

Method 3: P2 over RS485 with a virtual machine running BACnetP2

With this method, you have a device running BMS software or a BACnet Browser, with a virtual machine running BACnetP2. This is connected to an RS458 converter which is then connected to the rest of the system by P2 over RS458. The additional hardware needed is the RS485 converter.

Method 4: P2 over RS485 with a dedicated Linux device running BACnetP2

With this method, you have a device running BMS software or a BACnet Browser which connects via BACnet over IP to a dedicated Linux device running BACnetP2. The dedicated Linux device is connected to an RS458 converter which is then connected to the rest of the system by P2 over RS458. The additional hardware needed is the RS485 converter and a dedicated Linux device.
