FMI Layered Standard Network Communication

This repository contains a current prototype draft for the FMI Layered Standard Network Communication (fmi-ls-bus) based on the Functional Mock-up Interface 3.0 standard for the exchange of simulation models. Note that this draft is being worked on actively, and thus are subject to change without notice.

This is currently not normative, nor is this document to be considered officially endorsed by the Modelica Association or other involved organisations prior to official adoption.

The FMI 3.0 Layered Standard Network Communication is currently maintained on GitHub and is based on the FMI standard. The current state of development is published here and contains all bus types that are currently in development or are already final. Official releases are directly published via GitHub.

Roadmap

Different abstraction layers and types of buses are developed in different versions that build on each other. Corresponding milestones and a detailed roadmap have been defined for this purpose. The following graphic provides an overview of the planned sequence of supported bus systems:

A detailed roadmap showing completed, current and future work can be accessed here.

Getting Started

To help you get started, we provide introductory chapters. The following resources are currently available:

• Getting started with CAN, CAN FD and CAN XL

Demos

Demo FMUs are available within the FMI LS Bus Implementers' Guide to illustrate how to use and implement the fmi-ls bus. More demos will be added iteratively in the near future. See also the overview pages for the demos, categorized by the different supported bus types of the fmi-ls-bus.

FMI LS Bus Implementers' Guide

The FMI LS Bus Implementers' Guide is a free resource intended to give non-normative recommendations and guidance to implementers of the Functional Mock-up Interface Layered Standard Network Communication (FMI-LS-BUS).
