    • Multiport DNP (maximum 3 simultaneous connections)
    • DNP over Ethernet
See the technical note "Multiport DNP and ION Technology" for more information.

For more information on configuring this new functionality, see the DNP Slave Options module description in the latest version of the ION Reference.

New Pre-configured Modbus Slave Modules

Five new Modbus Slave modules have been added to the default meter framework.

    • Amp/Freq/Unbal
    • Volts
    • kW/kVAR/kVA
    • kWh/kVARh
    • PF/THD/Kfactor
For more information, see the "ION 7500 / ION 7600 / ION 8000 series Modbus Register Map" document.

Improved Ethernet Functionality

A new TCP/IP stack has been implemented.

7500/7600 Meters with V251 now support:

    • DNS (Domain Name Service) resolution. This allows users to enter a fully qualified domain name (e.g., rather than an IP address (e.g., 115.221.335.102) for the meters associated NTP (network time synchronization) or SMTP (email) server.
    • NTP (Network time protocol) time synchronization. This allows the meter to acquire time stamps from an internet server.
See the technical note "TCP/IP Network Connectivity" for more information.

For more information on configuring this new functionality, see the Ethernet Communications and Clock module descriptions in the latest version of the ION Reference document.
