Fatal alarm types can only be cleared by a reset command, therefore, they are always trapped.
• Fugitive
For some alarms (e.g. a communication error) there is only an alarm appearance event. These can only be
cleared by a reset command as there is no alarm disappearance event.
Therefore, fugitive alarm types are always trapped.
6.13.4. Alarm notification
Alarms are reported only when the corresponding event is logged into the logbook. Therefore, it is important that
the following events are selected for inclusion in the logbook:
• Non fatal alarm appearance
• Non fatal alarm disappearance
• Fatal alarm appearance
When an alarm is detected by the meter it can be reported in several ways:
• an alarm display on the meter LCD
• a triggered control output
• an SMS or email message
6.14. Remote Firmware Upgrade
There is a possibility to use the remote download functionality for a non MID meter only. The remote download
consists, in the first step, to load firmware applications by image transfer (COSEM protocol) in the meter, which is
still in nominal operation (the metrology is running). In a second step, the meter enters in downloading mode on
activation order (date or manual), the new firmware is written in flash, and it is taken into account by the next
power up. The time between FW activation and restart of the meter is <1min (metrology application do not run
during this time).
The following support tools are currently available to manage the remote Firmware Upgrade:
ACE Pilot (upgrade of meters only one after one)
ACE Vision (possibility to group the meters, in order to upgrade many meters with the same Firmware)
