Power-line communication PLC carries data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. It is also known as power-line carrier, power-line digital subscriber line PDSL , mains communication, power-line telecommunications, or power-line networking PLN. Windows Management Instrumentation WMI consists of a set of extensions to the Windows Driver Model that provides an operating system interface through which instrumented components provide information and notification. FCAPS is an acronym for fault, configuration, accounting, performance, security, the management categories into which the ISO model defines network management tasks. In non-billing organizations accounting is sometimes replaced with administration. An electricity meter, electric meter, electrical meter, or energy meter is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device.

Parts of this standard define interfaces relevant to each of the major business functions described by the Interface Reference Model. As used in IEC , a DMS consists of various distributed application components for the utility to manage electrical distribution networks. These capabilities include monitoring and control of equipment for power delivery, management processes to ensure system reliability, voltage management, demand-side management, outage management, work management, automated mapping, meter reading, meter control and facilities management.
This set of standards is limited to the definition of interfaces and is implementation independent. It provides for interoperability among different computer systems, platforms, and programming languages.
Methods and technologies used to implement functionality conforming to these interfaces are considered outside of the scope of these standards; only the interface itself is specified in these standards.
Typical uses of the message types include meter reading, meter control, meter events, customer data synchronization and customer switching. Although intended primarily for electrical distribution networks, IEC can be used for other metering applications, including non-electrical metered quantities necessary to support gas and water networks. The purpose of this document is to define a standard for the integration of Metering Systems MS , which includes traditional manual systems, and one or two-way Automated Meter Reading AMR Systems, with other systems and business functions within the scope of IEC The scope of this standard is the exchange of information between a Metering System and other systems within the utility enterprise.
The specific details of communication protocols those systems employ are outside the scope of this standard. The capabilities and information provided by a meter reading system are important for a variety of purposes, including but not limited to interval data, time-based demand data, time-based energy data usage and production , outage management, service interruption, service restoration, quality of service monitoring, distribution network analysis, distribution planning, demand reduction, customer billing and work management.

November Note: One of the strengths of the CIM is its flexibility. As technology advances, and new needs develop, new messages can be created. These new messages might involve additional systems not pictured. These new messages may leverage different options than the ones depicted in the example.
All UML-based communication diagrams and message flow diagrams contained herein are to be considered informative. All UML-based class diagrams contained herein are to be considered informative. The reader is referred to part 1 to locate the document that contains the normative definitions of the classes used in the CIM. Message format diagrams contained in the annexes of this document are to be considered informative. Message format diagrams can be construed to represent an XML schema.
The usecase provides a given context for the use of the CIM. Message format diagrams describe the elements which are passed. The elements depicted in dashed-line boxes are to be considered optional in a given context. The elements depicted in solid boxes are to be considered mandatory in a given context. If a diagram should depict an entire class as mandatory or optional, the reader should interpret this to mean that the use of the class is either mandatory or optional, but not that every element within the class is now mandatory or optional.
The reader must refer to the normative definition of the class to determine this.
