4 1.0 GENERAL INFORMATION 1.1 System Overview DLMS (Device Language Message Specification) Protocol is used in meters field and specifically in electric Energy meter to readout consumption and other values. The reference standard is EC This standard defines services which permit to read objects, OBIS defined. Inside these objects are mapped running meter values using standard profiles. By Gateway DLMS-MODBUS is possible to read DLMS energy meter s data using MODBUS RTU or MODBUS TCP protocol. The gateway is completely transparent to DLMS protocol, so user must know only Modbus protocol. This Gateway version reads data from one energy meter through the RS232 port or RS485 port or with optical probe and provides value on MODBUS RTU slave and on an Ethernet port Modbus TCP Server (up to 3 client connections).

5 1.2 Features Connections Gateway has following communication ports: 2 x Serial RS232 ports 1 x Serial RS485 port 1 x Ethernet port to read Energy meter s data by client Modbus TCP 1 screw connector to supply gateway VDC (min. 2 W) Front Signal LED for communication diagnostic 2 x Digital Input (*) 2 x Digital Output (*) (*) Their status is mapped in Modbus registers Digital Input connection The schema of two digital input/output connection is: User s Manual GW-DLMS-CEWE-INST Page 4

6 1.2.3 Serial port connections The schema of serial ports connections is: RS232-RS232 cable schema for optical probe User s Manual GW-DLMS-CEWE-INST Page 5

7 2.0 CONFIGURATION AND MODBUS MAP 2.1 Web Visualization To view the web pages containing the data read from the counter you need to connect to the network using the Ethernet RJ45 port available on the gateway. By a web browser, just type the default address In case of connection failure ensure that you have on your network card address on a subnet X. This brings us to the main screen of the Gateway with the values common to all Meter User s Manual GW-DLMS-CEWE-INST Page 6

8 From this page, through the links at the top, you can browse web pages that contain the data for the single Meter or go on the configuration pages of the Gateway (Home PLC). 2.2 Communication with energy meter In order to activate communication with energy meter user must insert in proper field Serial code Meter connected the serial number of connected meter. In case meter does not accept its serial number, please try with 1 to enable generic command. The confirmation of the changes is recorded using the Submit button. To make communication with meter working it could be necessary to know the password, depending on how the meter is configured. It s possible to change baudrate of the port connected to meter from Serial port baudrate selection in case meter works with speed different from 9600 that usually is standard. String debug is useful to understand the communication with meters. From this page, using the links in the upper part of the page, it s possible to move on the age with meter s data or in the gateway s configuration page (Home PLC). Default configuration is: meter connected to COM0 with RS232. It s possible to modify the used port: COM0, COM1 (RS232) e COM2 (RS485). Only for RS232 ports it s possible to modify the type of connection: RS232 or with optical probe. Changes are confirmed with Submit button. With GATEWAY REBOOT/APPLY CHANGES button you can force the gateway to reboot and apply changes to it. Modbus RTU for data reading is available on serial ports not used to connect to meter. 2.3 Gateway Settings To change the gateway settings, such as IP address, you need access to the configuration pages through the link HomePLC in the header of web pages that contain the data read from the counters. The Home page summarizes the main information concerning the gateway as the serial and with the navigation bar on the left you can move between the pages. Credentials to login and modify parameters are: Username = Admin, Password = Admin. Changes in gateway settings are applied to the gateway after a power reboot. User s Manual GW-DLMS-CEWE-INST Page 7

9 To change the parameters of the serial connections (baudrate, parity) and ethernet, such as the IP address, just go to the Devices page and, by clicking on the gear icon for the selected port, a popup will open with the settings. The two RS232 ports are COM0 and COM1 while the RS485 port is COM2. User s Manual GW-DLMS-CEWE-INST Page 8

10 To change the modbus node of the RTU or TCP server, open the Protocols page and modify the parameters of the desired interface. User s Manual GW-DLMS-CEWE-INST Page 9

11 2.4 Modbus Mapping Area The data read from the meters are placed in the Holding Register area. A copy of the values is also present in the 4x20000 holding register area. In case of obis not found in the message from meter you will find -1 value. Refresh time of the values is 3 seconds. Modbus addresses in the table are base 1; depending on used Modbus master, sometimes is required to swap words to read data correctly.
