Supports writing data (in both manufacturing and by FDM) to the module to support future
installation programming auditing.
Reading the auditing data is supported locally.
Auditing parameters include FDM User ID, number of dials, meter drive rate, unit of
measure, count rate, rollover, and PComp.
Timestamping of auditing parameters.
Log access via COSEM only.
Low Battery Event/Alarm
Note: For Cellular 500G Remote Modules, low-battery functionality is dependent on the
module's firmware version. For more information, see Device Firmware Functionality on
page 15.
The OpenWay Riva Cellular 500G Remote Modules' low-battery events are flagged when the
device reaches a 10% of battery life remaining state. The event triggers an alarm configurable
for asynchronous delivery to the head end system.
Cellular 500G Remote Module and Itron Security Manager
The Cellular 500Gremote module is a component of Itron's OpenWay Riva system. The
module's system security, provided by Itron Security Manager (ISM), applies to the RF
communications between the collection device and the module.
There are two fundamental security processes used in the Itron Security Manager to ensure
system communication confidentiality and validity.
Authentication. Authentication is the process of confirming that an artifact is genuine or
valid. Authentication in the module is the process of verifying a request is from a valid source
and in its original form.
Encryption. Encryption is the process of transforming information to make it unreadable to
anyone who does not have a valid security key. There are two types of encryption, symmetric
and asymmetric. Symmetric encryption uses a shared key to decrypt or encrypt information.
Asymmetric encryption uses a private key to encrypt and a public key to decrypt. Data
transmissions over the network are protected using AES-256 encryption.
As a component of the Itron OpenWay Riva solution, the module supports the security model
found in the OpenWay solution for both reading and programming. If the modules are shipped
without security enabled (ready to secure), the utility canat a later date—configure the
modules for ISM enhanced security.
