Data Sheet 98-1083 Rev AA 7
• Meter configuration information
Once this information has been sent the meter/endpoint starts collecting and sending based on the
default configuration loaded during manufacturing.
Retrieving Data
The endpoint performs data retrieval from the meter on request (ORR) or autonomously
(periodically reported).
Availability of the following features depends on meter configuration. On Request Reads (ORR)
available with this endpoint are:
• Register Data (Standard Table 23) which includes consumption, demand and TOU values.
• Load Profile or Interval Data (Standard Table 64).
• Revenue Integrity Services which includes instantaneous measurements related to line
voltage, current and phase angle.
Availability of the following features depends on meter configuration. Options for periodic reported
data with this module include:
• Register Data & Status Flags (Standard Tables 23 & 3) which includes consumption,
demand, TOU values and meter status.
• Load Profile or Interval Data & Status Flags (Standard Tables 64 & 3) which includes
interval data and meter status.
Demand Reset
When Command Center Host delivers a Demand Reset command, the communication module
passes the command to the meter, which performs the Demand Reset on the meter. The meter/
endpoint then passes the previous demand data captured by the meter (Standard Table 25) to the Host
for processing.
Time Synchronization
Time syncronization 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 the Host. The Host 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:
