About the 500WERTModule
OpenWay
®
Riva
The OpenWay Riva 500W ERT modules are radio-frequency water modules (RF) featuring
IPv6 open standards. The modules are designed to be read under Itron’s multipurpose
OpenWay Riva Network Mode or by legacy ChoiceConnect handheld, mobile and fixed
network readers.
In OpenWay Riva Network Mode, the ERT modules offer firmware download, sub-hourly
interval data, and extended data storage. In Mobile Mode, the ERT modules operate
identically to the 100W+ ERT module and can be read by legacy ChoiceConnect handheld
readers, mobile collection, and Itron's new Mobile Radio network readers. The 500W ERT
module continues Itron's tradition of reliability, accuracy, and long battery life while supporting
the industry's standards for security.
Note: The OpenWay Riva 500WERTModule was formally known as the OpenWay Riva
Water Module. The UIassociated with this device may reflect the former name.
Gen™5
Itron Gen5 500W ERT modules are radio-frequency (RF) water modules that connect to the
Gen5 Network as a leaf on a continuously powered device (CPD). The modules choose one
CPD as a gateway to the Gen5 network. The CPD communication with the modules is based
on a Limited Listening Schedule (LLS). The CPD handles the modules' messages, forwarding
and transmitting the module's messages. The modules can communicate in 100S System
Mode to support a ready-to-secure installation when a third-party work order system is used.
The utility configures the module to switch to the Gen5 Network Mode.
The CPD device accepts up to 20 modules at a time. The modules choose the CPD
association. Associated parent CPDs can change over time. The Gen5 500W ERT modules
are not IP-addressable. The Gen5 network head-end addresses the ERT modules through
the CPD and maintains a list of CPDs and associated 500WERTmodules. The CPD forwards
messages addressed to the 500WERT module. The modules continue Itron's tradition of
reliability, accuracy, and long battery life while supporting the industry's standards for security.
