RUTM59 DLMS

The information in this page is updated in accordance with firmware version RUTM_R_00.07.11.3.

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 RUTM59 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.

General status

---

This section displays DLMS general status information.

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

Clicking the Cog icon opens a modal window. The global configuration slider can be set and it's state saved.

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.

Test	-(interactive button)	Test device configuration.

Scan device parameters

---

After successfully adding the 'DLMS physical devices' configuration, and if the DLMS server is available, you can initiate a Device Parameters scan, which will write the parameters locally next to the cosem value configuration.

DLMS Cosem groups

---

To add a new cosem group, click the 'Add' button.

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

Test	-(interactive button)	Test cosem group.

DLMS Cosem value

---

Cosem value is a specific value retrieved from a defined server (physical device). To add a new cosem value, click the 'Add' button.

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