RUT271 DLMS
The information in this page is updated in accordance with firmware version RUT2M_R_00.07.10.4.
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 RUT271 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.
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.
DLMS Physical device configuration
The DLMS Physical device configuration section is used to configure the parameters of server (physical device).

| Encryption/Authentication encryption: Block cipher key | string (Length of the value must be 32); default: none | DLMS device block cipher key. |
| Encryption/Authentication encryption: Dedicated key | string (Length of the value must be 32); default: none | DLMS device dedicated key. |
| Logical name referencing | on | off; default: on | DLMS devices use Logical Names to reference and access specific data objects or attributes during communication. For example, when requesting data from a device, you might reference a specific Logical Name to retrieve the information. |
| 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.

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