Demand Reset
When Command Center delivers a Demand Reset command, the communication module passes the
command to the meter, which performs the Demand Reset on the meter. The meter/communication
module then passes the previous demand data captured by the meter (Standard Table 25) to
Command Center for processing.
Time Synchronization
Time synchronization is the process of keeping the meter time synchronized with the Gridstream RF
network time within a configurable limit. The communication module automatically keeps its time
synchronized with the Gridstream RF network via periodic background process. The communication
module reads the meter date/clock table (Standard Table 52) periodically, determined by its
configuration. If the time drift between the meter and communication module exceeds the
configured threshold, it sends a time synchronization alert message to Command Center. Command
Center schedules a time change event for the meter and sends it to the communication module. The
time of the change is determined such that the meter’s data integrity is maintained. At the scheduled
time, the communication module executes the standard procedure to change date/time on the meter.
Power Outage/Restoration
When an outage occurs, the meter uses an early power failure signal to alert the communication
module to disconnect from the meter's power immediately. The communication module saves
critical module data to non-volatile memory and creates and sends a power outage message. This
message includes the following information:
• LAN ID
• Outage time
• Reboot count
The communication module sends the message, then assists with routing other packets until the
back-up energy source can no longer keep the radio alive. The time that this energy source is
available varies with several factors, including amount of data packets being routed, environmental
conditions and age of meter/communication module. Generally, a hold-up time of ~120 seconds is
typical.
At restoration, the communication module first acquires network connectivity. With network
communications restored, the communication module sends a power restoration message that
includes details such as:
• LAN ID
• Outage time
• Restoration time
• Reboot count
The communications module stores a history of up to the last five power outage and restoration
event pairs. Command Center can request this data.
