Wireless M-Bus Stack for Automatic Meter Reading Smart Metering using Wireless M-Bus Wireless meter reading requires communication for small amounts of data with little protocol overhead. The Wireless M-Bus protocol has proven ist qualities in many field tests in different countries, and is becoming a quasi-standard for European smart metering. Firmware Options Since 2007, stzedn has been implementing a wireless M-Bus protocol stack supporting the following features. ●● Wireless M-Bus modes as specified in EN13757-4:2010 (T1, T2, S1, S1-m, S2, C1, C2, F2, N1, N2) ●● Application layer protocols »» EN13757-3 »» Open Metering Specification ●● Serial command set for ease of integration ●● Libraries for data link layer and application layer Serial API API Selection Layer ●● Protocol stack in source code Extended Data Link Layer (EN 13757-4.2011) DLL API Ongoing Development at stzedn ●● Wireless M-Bus modes according to EN13757-4:2010 (C1, C2, N1, N2) ●● Active participation in Open Metering Specification (OMS AG1) Data Link Layer (EN 13757-4.2011) PHY API Physical Layer (EN 13757-4.2011) ●● Support for different sub-GHz radio transceivers Hardware Abstraction Layer ●● Consulting, training and workshops ●● Firmware customization Contact For further information, please contact us at: Steinbeis Transfer Center Embedded Design and Networking (stzedn) Prof. Dr.-Ing.
