Taarifa ya Protokali

BACnet ni protokali ya mawasiliano kwa ajili ya Mitandao ya Usimamizi na Udhibiti wa Majengo (BAC) inayotumia ASHRAE, ANSI, na ISO 16484-5 standard protokali. Inarahisisha mawasiliano kati ya mifumo ya usimamizi na udhibiti wa majengo, ikiruhusu programu kama vile udhibiti wa HVAC, udhibiti wa mwanga, udhibiti wa ufikiaji, na mifumo ya kugundua moto kubadilishana taarifa. BACnet inahakikisha ufanisi wa kazi pamoja na kuruhusu vifaa vya usimamizi wa majengo vilivyokamilishwa na kompyuta kuwasiliana, bila kujali huduma maalum wanazotoa.

Bandari ya kawaida: 47808

Uhesabu

Mikono

pip3 install BAC0
pip3 install netifaces

import BAC0
import time

myIP = '<Your IP>/<MASK>' #You need to be on the same subnet as the bacnet device. Example: '192.168.1.4/24'
bacnet = BAC0.connect(ip=myIP)
bacnet.whois() #Broadcast request of bacnet devices
time.sleep(5)  #Wait for devices to respond
for i, (deviceId, companyId, devIp, numDeviceId) in enumerate(bacnet.devices):
print(f"-------- Device #{numDeviceId} --------")
print(f"Device:     {deviceId}")
print(f"IP:         {devIp}")
print(f"Company:    {companyId}")
readDevice = bacnet.readMultiple(f"{devIp} device {numDeviceId} all")
print(f"Model Name: {readDevice[11]}")
print(f"Version:    {readDevice[2]}")
# print(readDevice) #List all available info about the device

Kiotomatiki

nmap --script bacnet-info --script-args full=yes -sU -n -sV -p 47808 <IP>

This script does not attempt to join a BACnet network as a foreign device, it simply sends BACnet requests directly to an IP addressable device.
