Marcom OPC Server DLMS for RS485/232 networks, optical probe, modem or Ethernet TCP. Multi-connection support, advanced diagnostic functions. The **Marcom OPC Server DLMS** is an OPC Server for communicating with energy meters that implement the DLMS protocol (IEC-62056, IEC-62056-21, IEC-62056-42, IEC-62056-43, IEC-62056-61, IEC-62056-53, IEC-62056-46, IEC-62056-47 standards). It supports RS232, RS485 serial communication and with an optical probe, GPRS Modem communication, and TCP communication both as "Serial over TCP" and as "TCP Wrapper" (for DLMS protocol). A state-of-the-art OPC Server ideal for monitoring energy meters from all major manufacturers: **Landis+Gyr**, **Iskra**, **EMH**, **Actaris-Itron**, **Cewe**, **L&T**, **EDMI**, **Elster**, **Kamstrup**, **DPEE, ADDAD, Holley, Metcom, Secure Premiere, GELEX-EMIC** and many others... **COMPATIBLE WITH ELSTER A1700 METERS FOR READING ENCRYPTED AND PASSWORD-PROTECTED DATA** ****WITH THE POSSIBILITY TO DOWNLOAD *GENERIC PROFILES* FROM THE METER AND SAVE HISTORICAL DATA TO CSV FILE. It is now possible to configure the download of P.01, P.02 profiles and historical data for the IEC protocol and all profiles for the DLMS protocol, then schedule the download of the configured profiles as desired.**** The **Marcom OPC Server DLMS** offers high performance and great ease of use. As a leader in OPC product supply, Marcom is proud to distribute the distinctly best product on the market for OPC products communicating with DLMS meters: - Very high performance: communication over serial networks is optimized to ensure speed and reliability. - Simple and immediate configuration: just know the meter's communication speed and its address to add it to your network and have all device variables available. - Extremely convenient: a sizing system to adapt to any need The **Marcom OPC Server DLMS** allows fast and comfortable access to data present in energy meters of different brands using a single server. Variables are constantly addressed using the standard DLMS language. All data can be read with any client application compatible with OPC specifications. It is possible to simultaneously access an unlimited number of controllers. Configuration is done through a convenient graphical interface.  **Includes examples of already tested meter configurations.** - **ACTARIS-ITRON** with DLMS protocol and IEC readout - **ELSTER** with data exchange and readout - **EMH** with DLMS protocol and with data exchange, readout - **ISKRA** with DLMS protocol and readout (also using Consereth connection over TCP) - **KAMSTRUP 382J** - **LANDIS+GYR** with DLMS protocol and readout - **CEWE** with DLMS protocol and readout (for both PromoterW and Prometer 100) - **EDMI** with DLMS protocol - **ADDAD-5** with DLMS protocol Added connection type "**Serial port over TCP**": functionality that allows communication with meters directly over an ethernet port using the serial protocol. Added connection type "**Wrapper TCP/IP**" to communicate directly over TCP on port 4059 of meters that support this mode (e.g., CEWE Prometer 100 and Iskra MT880).   The main features of the OPC Server are: | Connection/Connections | Access to data from meters of all major brands. | |---|---| | Supported data types | All data present in the meter, totalizers, and instantaneous values of voltages and currents. | | Configuration | Intelligent configurator with automatic detection of address syntax errors | | OPC Specification | Compliant with OPC Data Access 2.04 specification | | OPC Data Types | VARIANT data types UI1, I1, UI2, I2, UI4, I4, R4, R8, BOOL as well as fields with these data types | | Supported operating systems | Windows 7/8/10/11 (32-bit and 64-bit) + .NET Framework 4.6.2. | | Multi-language support | Italian and English with online HELP |   --- Source: https://shop.marcomweb.it/en/dlms/opc-server-dlms MARCOM S.r.l. — a trusted supplier for industrial automation and building automation.
