For information regarding calendar clock accuracy and settings please see 
section 3.5. 

7.4 

Security log 

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. 

7.5 

Communication with other devices 

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.
