The supplier is advised to regularly review the security log for unexpected
entries, frequently enough that all log entries are read before being over-
written (the security log has a size of 100 entries and the content of the logs
are available to view on the meter LCD display or remotely).
In case of a security event, the security log can be read on-site on the LCD
via the Service Menu display after corresponding navigation using the
buttons A and B as shown in Figure 22 in section 14.2.
Note that access to the security log requires a breach of the meter terminal
cover to enable the Service Menu.
The security log can also be read by the remote parties using GBCS com-
mand ECS35b "Read ESME Security Log".
The security log is protected against deletion and filtering out of security
events.
The meter is fitted with an internal ZigBee communication module for the
transmission and receipt of data to and from the separate communications
hub device.
Communication with an external head end system (HES) gives the energy
utility the ability to remotely program individual or multiple meter points,
including tariff plans and configuration details
Support of Over the Air (OTA) firmware upgrades allows new functionality
to be sent to the meter. OTA ensures that the meter is future proofed and
mitigates the need to visit the meter when essential changes are required.
ZigBee Low Power Radio communication is also used to communicate with
other smart devices connected via the HAN including the in-home-display
(IHD) which allows the consumer to view real-time usage and pricing
information.
