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)
Note: The slow download (as done in IEC5 & IEC6) is always available with the following restriction: The
customer port can be configured by the customer in RS232 and RS485. But in loader mode, this port is
configured in RS232, so the slow download with a RS485 cable is not allowed.
6.15. UFER/DMCR and ABNT Protocol
6.15.1. UFER/DMCR
In order to penalize customers that have a too low power factor, a SL7000 function is in charge of handle specific
excess quantities. UFER and DMCR registers are implemented in SL7K IEC7. (by configurable parameter)
Following registers are implemented in IEC7:
UFER rate register
The excess energy over the UFER interval is accumulated in a rate only when the rate is active (current
rate). Only one rate is active at the same time.
