30. INSTALLATION, COMMISSIONING AND DECOMMISIONING
30.1. HAN Setup
The Installer should check all HAN Devices for suitability for joining the HAN
1. Install meters / Comms Hub and power up AS302P & Comms Hub.
2. Comms Hub automatically detects the WAN, Initiates comms with the DCC and requests to join the WAN.
– After validating the Comms Hub Device ID the DCC:
- Records the Comms Hub Device ID and WAN Address Mapping in its Inventory
- Confirms WAN joining to the Comms Hub
- Establishes Valid UTC Time to the Comms Hub
- Records the Comms Hub Device ID Mapping to the Gas Proxy Function Device ID
Mapping in its Inventory
- Updates the Status of the Comms Hub to be Commissioned
3. Installer recognises that the Comms Hub has successfully registered (WAN) and scans asset data IDs - AS302P,
Comms Hub and Gas Meter
4. Sends Asset Data ID’s to the Supplier
5. Supplier updates HAN Device Log and requests that devices be registered at the MPxN specified
6. The DCC, on receipt of such a Request, instructs the Comms Hub to:
1. Add the Devices to the Comms Hub Device Log
2. Allow joining (set the Comms Hub to “pairing mode”)
7. HES instructs Comms Hub to allow HAN Device Joining for Fixed Time Period. Comms Hub is set to “Pairing
Mode” for a minimum of 3600 seconds (1 hour)
8. Comms Hub successfully creates HAN
9. Installer advised that meters can be joined to HAN and initiates Meter Join
30.2. Meter Commissioning
1. Installer Initiate Request for IHD & AS302P to join HAN
2. Power up the AS302P, if it is not connected to a network then it will show the commissioning screen
– This screen will remain present for one of the following lengths of time, whichever is shortest:
- 30 seconds
- Until the commissioning process starts
- Until a pushbutton is pressed to step through the display
– The meter also allows navigation to this screen though the menu structure.
– Pressing and holding the top button activates the Commissioning process.
– The screen will change to a HAN Status screen, this will step through the following items (see steps
below):
- Scanning for Network
- Doing key establishment
- Scan for tunnel
3. AS302P sends NWK Join Request with Certificate Based Key Exchange
4. AS302P and IHD join HAN with ZigBee Network and Link Connections to Comms Hub. There is no IHD to AS302P
data at this stage.
