Single Stack
End device

Compliant to EN 13757-3/-4/-7 (Wireless) M-Bus and OMS® Specification

Low complexity and optimization of energy consumption

Bidirectional as well as unidirectional communication possible

Pre-certification on reference hardware platform
The OMS® Stack for End Devices is the proven software solution for metering applications from our product portfolio and comes with some new features in OMS® version 4.5.1. The stack implements all the protocol elements required for Wireless M-Bus compliance and covers a large part of the options and features specified in EN 13757 and its sub-standards, with a focus on the most commonly used options and features.
This single stack is optimized for a compromise between small footprint, excellent modularity and scalability, but still rich in features. With the OMS® v4.5.1 Stack, you can be sure to equip your products with a proven and constantly evolving software solution.
Optimization of energy consumption and usability of utilities (as e.g., CRC or AES) by application
Quick stack adaption to different use cases
With a directly available OMS® v4.5.1 Standard Stack you shorten your time-to-market significantly

The code sizes described above indicate the typical memory requirements for operating the fully equipped protocol stack as a library, including associated drivers. The values are based on the specified reference hardware
Our Protocol Stack package includes everything you need for integration:
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:
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.
