Software gateway for the conversion between DLMS protocol and Modbus/TCP-RTU

Select desired model

The Marcom DLMS to Modbus software manages the protocol conversion between DLMS (protocol typically present on electrical energy meters) and Modbus/RTU.

The software allows you to interface to the optical port (with accessory USB optical probe or Serial Optical Probe) or on RS232 / RS485 port of the counter that implements the DLMS protocol and to convert the acquired data in Modbus memory areas. The software supports the Modbus RTU and TCP communication, and can act as Slave or as Master.

The product acts as a gateway and allows to put in communication between their equipment with the communication systems of different physical levels.

The configuration is done through a convenient graphical interface, either manually or through a tool for importing from Excel file. Existing configurations can be exported to Excel for example by visualization systems or process control in order to be easily uploaded to the Marcom DLMS to Modbus.

Including configuration examples of counters already tested.

  • ACTARIS-ITRON with DLMS protocol and readout
  • ELSTER with data exchange and readout
  • EMH with data exchange , readout and readout on ethernet ( new!!)
  • ISKRA with readout
  • Kamstrup 382J
  • LANDIS with DLMS protocol and readout
  • CEWE with DLMS protocol and readout (for Prometer W and also for the new Prometer 100)
  • EDMI with DLMS protocol
  • ADDED-5 with DLMS protocol

Introduced READOUT ON ETHERNET: brand new feature that allows you to communicate directly with the counters on Ethernet port using the serial protocol .

Introduced  "WRAPPER TCP" mode to comunicate directly on TCP port 4059 of meter that support this mode (Es. CEWE Prometer 100).


The scenario for using the software is the following:
Concentrator: In this mode the software is configured as Master DLMS on some of its serial/optical interfaces. Through these interfaces, the software goes to interrogate the counters and maintains the acquired values in the memory. The values are then made available as Slave Modbus RTU and / or TCP for requests from the PLC, devices, SCADA that interrogate the product.

The main features of the OPC Server are:

Connections Access to datas of main manufacturers meters
Supported Data Types All data in the counter, totalizer and instantaneous values ​​of voltages and currents.
Supported OS Windows 7/8/10 (32 bit and 64 bit) + .NET Framework 4.0
Multilanguage Support Italian and English with HELP online
