M-Target for Simulink Version 2.20 from Bachmann Electronic provides a new interface between Matlab and the M1 real-time controller. Online values can be read directly from the controller system from the Matlab console or scripts and are immediately available for further calculations and evaluations. This extension is available for all M1 CPU classes. Further improvements and support up to Matlab/Simulink R2018a round off the new version. This enables model-based development with modern engineering tools. This is particularly useful when a system consists of several complex subsystems or the creation of a necessary prototype would exceed the project budget in terms of time and money. Code generated from a simulation model is installed directly on the M1 real-time system with M-Target for Simulink and executed there as an independent application. Neither manual steps nor additional engineering tools are required. This direct method of model-based development is also being expanded with the latest version of M-Target for Simulink V2.20.
