The information in this page is updated in accordance with firmware version RUT361_R_00.07.07.1.

Summary

The DLMS / COSEM standard suite (IEC 62056 / EN 13757- 1) is the most widely accepted international utility meter data exchange standard. DLMS is the application layer protocol that transforms the data into messages and COSEM describes the general object model and can be used for all kinds of presentations.


This manual page provides an overview of the DLMS functionality in RUT361 devices.

Note: DLMS is additional software that can be installed from the System → Package Manager page. Note: The count of DLMS connections is limited to 30, physical devices - up to 30, space groups - up to 10, cosem objects - up to 20 in each group.

Main

The Main page is used to configure DLMS physical devices and Cosem Groups.

Notice the Global section config. It is used to outright turn the service off or on if any active configurations are present.

DLMS Physical devices


Interoperable devices in DLMS categorize as server (physical device) and client. Data collection device act as a client that supports system dependent features, parameters, functions and classes requesting data from the server (physical device). In this structure, communication protocol stack is independent of application layer so both devices may communicate different media. To add a new physical device, click the 'Add' button.

After clicking 'Add' you will be redirected to the newly added physical device's configuration page.

DLMS Physical device configuration


The DLMS Physical device configuration section is used to configure the parameters of server (physical device).
