Communication architecture and contracts
Define embedded communication interfaces and specifications so connected components share an agreed interpretation of exchanged information.
Capability
Connectivity, Diagnostics & Interfaces
Define and integrate communication boundaries between embedded components, devices and upstream systems.
Communication work covers the contract between connected elements as well as implementation and configuration. Protocol selection and diagnostics scope follow the actual system, its interfaces and the assignment boundary.
When to involve CEVOLARION
- Components exchange data but disagree on interface behaviour or configuration.
- A platform needs measurement, calibration or diagnostic interfaces integrated with its software baseline.
- An embedded device must connect to an upstream system while preserving clear responsibilities at the interface.
Engineering scope
The agreed assignment determines which activities are included and where the responsibility boundary sits.
Embedded networks and configuration
Implement or configure communication stacks and interfaces using CAN, CAN FD, LIN or Ethernet where appropriate to the system.
Measurement and calibration interfaces
Support measurement or calibration communication, including XCP/CCP-style interfaces where the platform and assignment require them.
Diagnostics integration
Clarify required diagnostic behaviour and integrate the agreed interfaces. The supported platform and precise diagnostic scope are established during technical scoping.
Device, edge and upstream integration
Connect embedded devices with edge or upstream systems, including MQTT or REST-based interfaces where relevant to the system architecture.
Interfaces to adjacent disciplines
Systems & Requirements Engineering
Make communication responsibilities and interface requirements explicit in the system definition.
Embedded Software & Platform Engineering
Connect communication-stack behaviour and configuration to platform implementation.
System & Software Integration
Resolve cross-component assumptions and verify the resulting interface behaviour in the integrated system.
Example engineering outputs
Outputs are assignment-dependent and agreed for each engagement.
- Interface specifications and communication contracts.
- Communication-stack and network configuration.
- Agreed diagnostic or measurement-interface behaviour and integration records.
- Interface test configurations and findings.
Methods and engineering environment
- CAN / CAN FD, LIN and Ethernet in applicable embedded-network contexts.
- XCP/CCP-style measurement and calibration communication where relevant.
- MQTT or REST interfaces for applicable device, edge and upstream connectivity.
- Interface specification, configuration review and integration testing.
Where this discipline connects
Highlighted stages indicate typical connections. The actual entry point and scope follow the product and assignment.

Delivered at the scale of the work
This capability can contribute to specialist work, an Engineering Cell, a Defined Work Package or an agreed Managed Service. The collaboration model and partnership tier are separate decisions.
