1.Introduction
The STG series provides a cutting-edge solution for converting Wireless M-Bus (WMBus) OMS (Open Metering System) data to Modbus protocols, enabling seamless integration between advanced metering systems and industrial automation platforms. By focusing on Modbus TCP and RTU compatibility, the STG series ensures interoperability and ease of deployment in diverse operational environments.
2.Why Convert WMBus OMS Data to Modbus?
Wireless M-Bus is the preferred communication protocol for smart meters, transmitting real-time utility consumption data wirelessly. However, industrial control systems like SCADA and PLCs primarily rely on Modbus for data exchange. The STG series bridges this gap, ensuring metering data can be integrated into industrial systems for centralized monitoring and control.
3.Exclusive Features for Modbus Conversion
Unlike general-purpose data parsers, the STG series is tailored specifically for converting Wireless M-Bus OMS data to Modbus protocols. Key features include:
• WMBus OMS to Modbus TCP Converter: Facilitates integration with Ethernet-based networks by converting WMBus data into Modbus TCP format.
• WMBus OMS to Modbus RTU Converter: Enables communication with legacy devices via serial interfaces using Modbus RTU.
• Flexible Transparent Mode: Sends raw WMBus packets to/from TCP/IP or serial interfaces for custom applications.
• OMS Compliance: Full support for OMS encryption and standardization ensures compatibility and data security.
• Advanced Diagnostics: Built-in tools for monitoring communication and debugging issues during system setup.
4.Step-by-Step Guide to Using the STG Series for Modbus Conversion
1. Configuration:
o Connect the STG device to your computer via TCP/IP interface.
o Use the bultin web interface to configure the desired Modbus mode (TCP/RTU).
o Enter OMS encryption keys and set the communication frequency for the WMBus network.
2. Data Reception:
o Position the STG device within range of the Wireless M-Bus meters.
o Start data reception using the software. The STG device will decode OMS packets and prepare them for Modbus transmission.
3. Modbus Integration:
o For Modbus TCP: Connect the STG device to an Ethernet network and configure the Modbus master to communicate with the STG’s IP address.
o For Modbus RTU: Connect the STG device to a serial port and ensure the Modbus master is set to the correct baud rate and communication parameters.
o Map the WMBus data to Modbus registers as needed for your application.
5.Unique Applications of the STG Series for Modbus Conversion
