Wired M-Bus / OMS® v4.5.1 for Master Devices

Single Stack

Master

Compliant to EN 13757-2/-3/-7 (Wired) M-Bus and OMS® specification

Decryption of up to 20 slave devices to one master

Reliable and efficient data transmission for M-Bus networks

Seamless integration with existing systems

Wired M-Bus / OMS® v4.5.1 for Master Devices

The Wired M-Bus Protocol Stack for Master Devices is a robust and efficient solution for remote reading of slave devices within a Wired M-Bus network. It enables data transmission from numerous meters and sensors and allows the device to manage a large number of connections simultaneously.

Ideal for settings where devices are installed relatively close to each other or where existing infrastructure can be leveraged, this protocol stack ensures seamless data transmission at a cost-effective setup.

The Wired M-Bus Protocol Stack for Master Devices is an implementation of the standards EN 13757-2/-3/-7, together with the OMS® specification 4.5.1, dedicated to specifying wired communication for M-Bus.

Frequently asked Questions

What is included in the STACKFORCE software package?

Our Protocol Stack package includes everything you need for integration:

  • Precompiled stack library
  • Hardware-specific drivers
  • Serial interface (UART, SPI, etc.)
  • Power management
  • Example applications for quick integration
  • Documentation

The Protocol Stack itself is delivered as object code and cannot be directly modified. The platform interface (including HAL and RF driver integration) is provided as source code. This allows you to:

  • Adapt the platform driver to your target hardware
  • Configure specific radio settings such as frequencies
  • Optimize driver behavior
  • Add your own components such as security and timers

For further adjustments to the stack itself, we are happy to support you with specific development services.

Yes, that’s possible. In addition to our standard solutions, we offer customer-specific extensions of our Protocol Stacks. This enables us to implement your specific requirements so that the stack integrates seamlessly into your system environment.

We are happy to check compatibility with your specific hardware. If your hardware meets the minimum requirements for running a Protocol Stack, porting is generally possible. We can discuss the porting effort with you or provide our Platform Porting Guide so you can perform the porting yourself.

Yes. You can request a free evaluation license and test the software in your target environment – without obligation and risk-free. More information about the evaluation offer can be found on our website under: Evaluation License.

STACKFORCE uses a multi-stage testing process to ensure high software quality. This includes:

  • Unit, module, and firmware tests to check the functionality and stability of individual components
  • Static code analysis to detect errors and vulnerabilities at an early stage
  • Automated system tests on simulated and real hardware
  • Regression tests to ensure that existing functions continue to work reliably and that no new errors are introduced
