RUT240 DLMS

The information in this page is updated in accordance with firmware version RUT2_R_00.07.06.16.

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 RUT240 devices.

Note: DLMS is additional software that can be installed from the System → Package Manager page.

Main

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

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, enter an new configuration name and 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).

Field	Value	Description

Test	-(interactive button)	Test device configuration.

DLMS Cosem groups

---

To add a new cosem group, enter an new configuration name and click the 'Add' button.

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

DLMS Cosem group configuration

Name	string; default: previously added cosem group name	OBIS code group name.
Interval	integer [1..4294967295]; default: 1	Interval for OBIS code reading (in seconds).
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, enter an new configuration name and click the 'Add' button.

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

Field	Value	Description
Enable	off | on; default: off	Enables Cosem state.
Name	string; default: previously added cosem value name	COSEM option name.

Entries	interger [1..32767]; default: none	How many data objects to read.

Connections

The Connections page is used to configure DLMS connections. You can use either TCP or serial (depending on the router) connection to establish a connection between the physical device and the router.
