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.

The following note is reused word-for-word in the Logging overview and Burst data logging concept topics.
NOTE: To maximize the performance of your power management system, it is recommended that devices be connected directly to an Ethernet network.
Previous wording was: Whenever possible, always use a direct Ethernet connection from the meter to the software system to maximize network communications performance. Connecting meters using serial or Ethernet-to-RS485 gateway methods significantly reduces the available bandwidth and can cause multi-mastering problems.

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.
