In BAC0, Is it possible to expose actual points to Bacnet Server Points ?
Daniel-V-Richardson opened this issue · 7 comments
Hello,
I don't know whether my question makes any sense, but i have a requirement and i don't know how to achieve it.
I have Created a network with the below details :
client = BAC0.lite(ip=networkAddress, port=networkPort, deviceId=device_id)
After this i am discovering devices and adding them to my db and then adding points for each device respectively to my db aswell. I am using Room Control Simulator as a Bacnet Device and it's points.
Now I need to export these Imported DB Points as Bacnet points based on the client which i had created before, and i can do this by using object factory, which is working fine. But my requirement is, I need to establish a link between the exported bacnet point and the actual point. Which means if i try to update the setpoint1 of the exported point. then it should also reflect on the actual setpoint1.
I am trying to achieve this functionality for a long time but I am a beginner to field and i don't really get the entire picture. Please Help me out!
Thanks.
@bbartling This (#381) script is just trying to simulate a bacnet device which is then discovered by another device. But want i wanted was kinda different. For example I have a bacnet device let's say an AHU device exposed on port 47808 simulated by niagra, and i have discovered it and enabled polling in my BAC0 application which used BAC0 library, now i want to export the same points of the simulated AHU on port 47809 which will be exposed as BAC1 points from my application. Now if i dicover the BAC1 device's points in another device i want the actual polling of the Original AHU's points to be happening, and also if i try to write to any point it should write not only the exported point from BAC0 device but the original point too. I don't know if i'm clear enough but this is what my understanding and requirement is. Thank You for your reply.
Not sure why you need that. From BAC1, you can point directly to BAC0 (the port, not the app) using unicast (a direct connection). I see no need for an intermediate device.
BBMD are used to make broadcast messages work on different subnets. If you know where to connect and don't need broadcast, a direct connection will work.
I think you need a BBMD, right @ChristianTremblay/BAC0 @.> ? You can run 2 BACnet apps on one OS but I they need a BBMD to route data between them. I have actually never done this before. That's what you want right? Run 2 apps on one machine and then read/write between the two?

Yes I understand it's kinda unnecessary, but i just wanted to try it out as niagra does it pretty efficiently, and not only bacnet to bacnet, i also wanted to expose modbus points to be converted as Bacnet points from my application too.
