Шлюз KNX в BACnet/IP: Intesis IN701KNX и настройка ETS6

Технические характеристики IN701KNX

Model comparison:
  IN701KNX          — 1,000 bidirectional signals
  IN701KNX300000    — 3,000 bidirectional signals

Physical:
  DIN-rail: 4 modules (72mm width)
  Power supply: 24VDC ±10%, 150mA (not from KNX bus)
  KNX TP: screw terminal, 30mA bus power draw
  Ethernet: RJ45, 10/100 Mbit/s
  USB: Type-B, configuration only

BACnet role:
  BACnet/IP server (not client)
  Responds to BACnet WhoIs broadcasts
  Handles COV (Change of Value) subscriptions
  Supports BACnet Read/Write Property services
  BACnet/IP port: 47808 (0xBAC0) default

Настройка проекта MAPS — три обязательных параметра

1. BACnet device instance
   Must be unique across the entire BACnet network
   Example: 10001 (check with BMS engineer for conflicts)
   Range: 0 – 4,194,302

2. KNX individual address
   Assign in ETS6 before MAPS configuration
   Example: 1.1.250 (area 1, line 1, device 250)
   The address must be programmed into the gateway
   via ETS6 download before MAPS sends KNX telegrams

3. BACnet/IP port
   Default: 47808 (0xBAC0 in hex)
   Change only if another BACnet device on the LAN
   uses the same port — rare in practice

Пример таблицы сигналов интеграции AHU

Signal  BACnet Object    KNX GA      DPT        Direction   Description
001     AV 001 (REAL)    4/0/1       DPT 9.001  K→B→K      Room setpoint (°C)
002     BV 002 (BOOL)    4/0/5       DPT 1.001  K→B        Occupancy status
003     AV 003 (REAL)    4/0/10      DPT 9.001  B→K        AHU supply air temp
004     AV 004 (REAL)    4/0/15      DPT 5.001  B→K        AHU fan speed %
005     BV 005 (BOOL)    4/0/20      DPT 1.001  B→K        AHU run/stop status

Integration flow:
  KNX PIR detector → GA 4/0/5 (DPT 1.001) → IN701KNX → BACnet BV 002
  Desigo CC reads BV 002 → triggers AHU occupancy mode via RLU220
  RLU220 supply air temp → IN701KNX BACnet AV 003 → KNX GA 4/0/10
  Gira X1 room display reads GA 4/0/10 → shows supply air temperature

Шаги интеграции с Desigo CC

1. Desigo CC Management Station
   → System → Networks → BACnet driver
   → Add Network: BACnet/IP, BBMD address if needed

2. Discover or manually add IN701KNX:
   → Add Device: IP = 192.168.1.250, Instance = 10001
   → Desigo CC queries device for object list

3. Auto-import object list:
   → All configured AV, BV, MSV objects appear
   → Check names match MAPS signal descriptions

4. Bind to Desigo CC functions:
   → Alarms: bind BV objects to Alarm Management
   → Trends: bind AV objects to Trend Log objects
   → Graphics: drag AV/BV to floorplan graphics

Point-based licensing note:
   Each BACnet object imported into Desigo CC
   consumes one point licence. Confirm total count
   with Siemens before ordering the licence package.

Последовательность проверки при вводе в эксплуатацию

KNX → BACnet direction test:
  1. Open ETS6 Group Monitor
  2. Send write telegram to GA 4/0/1 (value: 21.5°C)
  3. Open MAPS Diagnostic tab
  4. Confirm Signal 001 shows updated value 21.5
  5. Open Yabe BACnet Explorer → Read AV 001 Present Value
  6. Confirm Yabe reads 21.5 ✓

BACnet → KNX direction test:
  1. In Yabe: Write AV 001 Present Value = 22.0
  2. MAPS Diagnostic confirms write received
  3. ETS6 Group Monitor shows telegram on GA 4/0/1
  4. Value = 22.0°C ✓

Diagnostic LED status (IN701KNX front panel):
  PWR (green solid)   — 24VDC power OK
  KNX (green blink)   — KNX bus active, telegrams exchanged
  ETH (green blink)   — Ethernet link active
  ERR (red blink)     — configuration error or signal fault
