Communications
Communications overview
Communications is the transfer of data to and from the meter and is controlled by a combination of
hardware and software components in the meter.
For each connected communications port, the meter uses the applicable communications
protocol to establish communications with other devices or software. The protocol manages the
communications session and defines the set of rules, commands, and packet structure of the
transmitted data. You can also control which protocols are enabled or disabled on the meter.
NOTE: To maximize the performance of your power management system, it is recommended
that devices be connected directly to an Ethernet network.
Other means of controlling communications, such as who can access certain types of meter data,
are discussed in the security topics for the meter.
Your meter's default protocol settings meet the needs of most systems with only basic
configuration. You can customize these settings to meet your specific needs. These are
advanced procedures that require an understanding of your meter's architecture, supported
protocols, and the communications network and power system that your meter is connected to.
Ethernet communications
Your Ethernet connection source should be installed in a location that helps minimize the overall
Ethernet cable routing length and complexity of your network.
The meter supports a single IP address for both physical Ethernet connections.
Your device's second Ethernet port acts as an Ethernet switch to help simplify network
connections and reduce installation time and costs, by having shorter Ethernet cable runs
between devices without needing additional Ethernet routers or repeaters. You cannot connect
your meter to two different Ethernet networks. The two Ethernet ports do not split the signal, so
connecting both ports should not impact your communications speed.
The meter uses dual-stack IPv4/IPv6 routing technology to manage network communications and
allow network hosts to communicate with the meter using either IPv4 or IPv6.
Ethernet communications connections
Your meter's dual port Ethernet connections enable you to use straight-line or network loop (ring)
topology.
If local network loop Ethernet topology is required, you must enable RSTP for your meter's
Ethernet communications to function.
Use CAT5 (or higher) Ethernet cables with unshielded RJ45 modular connectors to wire your
meter's Ethernet communications.
