Third Party Protocols
Modbus and DNP modules are factory configured and do not require basic
configuration changes. Changing the factory configuration is an advanced setup
procedure that requires an understanding of the protocol, as well as an
understanding of the meter’s internal operation.
Refer to the technical notes DNP 3.0 and ION Technology, and Modbus and ION
Technology for the appropriate list of parameters available for each protocol.
N OTE
The meter can also be configured to receive data through Modbus or DNP 3.0, though there is no factory-
configured framework for receiving data through these protocols. For details on configuring your network
for receiving data via Modbus or DNP 3.0, refer to the DNP Slave Import module and Modbus Slave
Import module descriptions in the online
ION Programmer’s Reference , as well as the technical notes
DNP 3.0 and ION Technology, and Modbus and ION Technology .
Communications Protocol Configuration
In order to use the factory Modbus or DNP configuration you must first configure
the communications channel you want to use. By default, all communications
ports are configured to use the ION protocol. Choose the 3rd-party protocol you
want from the list of available protocols in the Communications module’s Protocol
setup register.
N OTE
Modbus RTU is available on each of the meter’s communications ports, and multiple ports can
communicate using Modbus simultaneously. Only a single port can use the DNP 3.00 protocol at any
one time.
