IEC62056-53: COSEM Application Layer

COSEM (Companion Specification for Energy Metering)

defines an Application Layer protocol that can handle Meter

data and perform the basic functions of data set/get/action

operations in the Meter. In addition to these, COSEM

handles access rights, client-server connection handling,

abstracting meter data from/to COSEM class instances,

framing data into COSEM packets, high-level segmentation

of data into blocks etc.
