  The development of Industrial Internet of Things systems (IIoT) requires
tools robust enough to cope with the complexity and heterogeneity of such
systems, which are supposed to work in safety-critical conditions. The
availability of methodologies to support early analysis, verification, and
validation is still an open issue in the research community. The early
real-time schedulability analysis can help quantify to what extent the desired
system's timing performance can eventually be achieved. In this paper, we
present CHESSIoT, a model-driven environment to support the design and analysis
of industrial IoT systems. CHESSIoT follows a multi-view, component-based
modelling approach with a comprehensive way to perform event-based modelling on
system components for code generation purposes employing an intermediate
ThingML model. To showcase the capability of the extension, we have designed
and analysed an Industrial real-time safety use case.
