Optional Features
Event Log
The C12.19 C1SD/T/L register has an Event Log that records historical events that have
taken place in the meter. The events to be logged must be configured via the PC-PRO+
Advanced programming software. To aid in troubleshooting, Itron recommends enabling all
events to be logged.
In order to have date and time associated with an event, Time-of-Use or Load Profile
is required. A Demand-only register allows for event log recording; however, in the
event of a power outage, the date and time will not be reliable.
The C12.19 C1SD/T/L register Event Log is circular in nature, allowing for the capture of
the most recent events in the meter at all times. The register is capable of retaining 420
events prior to wrapping.
Each event log record includes an event description, a time and date stamp, and additional
information on certain events.
