Crate mabi_bacnet 

mabi-bacnet

BACnet/IP simulator for the OTSIM protocol simulator.

This crate provides:

• BACnet/IP server implementation with UDP networking
• BACnet object model (AI, AO, BI, BO, AV, BV, MSI, MSO, MSV, Device)
• Property services (ReadProperty, WriteProperty, ReadPropertyMultiple, WritePropertyMultiple)
• COV subscriptions and notifications
• Device discovery (Who-Is/I-Am)
• BBMD (BACnet Broadcast Management Device) for cross-subnet communication
• APDU segmentation for large message handling

Architecture

The crate follows a layered architecture:

Quick Start

use mabi_bacnet::prelude::*;

// Create object registry
let mut registry = ObjectRegistry::new();

// Add analog input object
let ai = AnalogInput::new(1, "Zone Temperature");
ai.set_value(72.5);
registry.register(Arc::new(ai));

// Create and run server
let config = ServerConfig::new(1234);
let server = BACnetServer::new(config, registry);

server.run().await?;
