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.

NOTE

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.

NOTE

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.
