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 up to three meters through the RS485 port and provides value to two RS232 port MODBUS RTU slave and on an Ethernet port Modbus TCP Server (up to 3 client connections) ISKRA MT880 compatibility The MT880 counter is not compatible with the gateway by default. It is therefore recommended to ask the installer / seller of the counter to change the counter configuration like this: activate the IEC protocol on the serial port to be connected to the gateway reduce to a maximum 2 the number of previous values of the obis in the readout message of the counter User s Manual GW-DLMS-485-ISK Page 3

5 1.2 Features Connections Gateway has following communication ports: 2 x Serial RS232 port to read energy meter s data by master Modbus RTU 1 x Serial RS485 port to connect up to three energy meter 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-485-ISK Page 4

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-485-ISK Page 6

8 From this page, through the links at the top of the page, 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 coder Meter x the serial numbers of connected meters. 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. Time between readouts can be set from 10 to 3600 seconds. String debug is useful to understand the communication with meters. With GATEWAY REBOOT button you can force the gateway to reboot. The confirmation of the changes is recorded using the Submit button. 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-485-ISK 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. Modifications to the COM2 port are not necessary as the parameters are forced by the software. User s Manual GW-DLMS-485-ISK 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. 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 approximately: Time between readouts * N, where N is the number of energy meters connected to gateway and configured with a serial number different from zero in HomeDLMS. Modbus addresses in the table are base 1; depending on used Modbus master, sometimes is required to swap words to read data correctly.

A : this indicates which energy meter is reported B : this indicates the type of error 5 : serial port is not correctly opened 7 : message from energy meter is too big for gateway s buffer; this error does not compromise gateway s normal functionality, but last part of obis list will be lost 8 : message from energy meter is empty -> please check cable connection There are also : 888 : global timeout error (this happens if there aren t meter s serial number in modbus area) 999 : hardware/software authenticity error User s Manual GW-DLMS-485-ISK Page 13
