Meter Installation - Temp No Wan; Meter Decommissioning - Honeywell AS302P Operating Instructions Manual

50

AS302P Single Phase Smart Meter

____________________________________________________________________

5.

AS302P– Joins Time Server {Time Invalid/Unreliable}

6.

Establish Tunnel for End to End Communications via the Comms Hub to allow End to End Messages meter to/from

DCC.

7.

AS302P sends an Automatic Commissioning Alert Notification

8.

Supplier sends Commission Device (via DCC) message to AS302P

9.

AS302P performs Clock Sync with Comms Hub and displays MPAN

10. The meter now offers the opportunity to join other HAN devices to the meter, this could be up to:

7 - Type 1 devices (which could be up to 5 HCALCS, therefore 2 other Type 1 devices could be added)

4 - Type 2 devices

11. This is achieved with a Service Request (SR) which writes the Device ID of the devices to be joined to the HAN

into the Device Log of the AS302P. (Method B Join)

If configured to be shown during the manufacturing process, information on the devices connected to the meter

will be available to view in the HAN info menu.

12. AS302P verifies the Cryptographic Protection, updates its Device Log & undertakes the ZigBee Key

Establishment Process with the other devices

13. The Supplier configures the Meter through further Service Requests (SRs) via the DCC.

30.3. Meter Installation – Temp No WAN

In case of a No WAN Availability, the process follows the process above, except Message Delivery and Response is via

DCC back to Supplier to a HHT to the Comms Hub with the following observations:

–

HHT Process to Connect to the Comms Hub is still not confirmed via GBCS Change and TBDG.

–

HHT needs a robust connection to Suppliers Systems to make the Installation Viable due to sequencing of

Commands and Responses

–

The AS302P is likely to remain on its Own Time (from factory) but identified in GBCS terms as "Unreliable"

until a Comms Hub WAN connection is established

–

Suppliers could provide all Configuration and Certificate Updates (where required) delivered via HHT, but

there could be some requirements for Buffering/Message Sequencing via the HHT

–

The Device Certificate Process update obligation on Suppliers post installation is expected to be dependent

on establishing a WAN Connection.

30.4. Meter Decommission and Removal

Honeywell would recommend the following process is followed (assuming meter is still communicating to DCC).

–

Supplier requests and obtains Closing Reads, Financial Status. Event Logs, etc.

–

Supplier issues Set Tenancy Date to restrict data (Electricity or Gas Proxy Function)

–

Supplier issues Unjoin Commands to remove Meter Connections from IHDs, PPMIDS, HCALCS

–

Supplier issues Remove Device from Comms Hub Log, to Remove the Device from the ZigBee Network

with the Comms Hub

–

Supplier issues Decommission Request to DCC (DUIS Interface no meter impacts)

–

Meter returned and subsequent actions dependent on reason for removal.

If the meter is not being used again e.g., being disposed of, then the Utility is responsible for ensuring that all sensitive data

is removed before disposal of the device.
