COSEM (''Companion Specification for Energy Metering'') is a protocol that falls under the DLMS standard, and it provides application and transport layers for the protocol. COSEM defines a set of '''objects''' that represent the data and functions of the meter, and a set of '''services''' that allow the client to access the objects. COSEM also specifies the '''security''' mechanisms for authentication and encryption of the messages. It should be noted, that for now our implementation of COSEM only allows us to perform read operations on DLMS servers, with write operations not currently supported.

For this example we will be using a three phase electricity meter made by CLOU Electronics with a model number of '''CL730S22'''. We will be demonstrating the configuration of TCP/IP connections as well.
