The focus of our research work is on readily accessible, embedded, real-time development with concurrency support. To this end, we develop the Real-Time For the Masses (RTFM) programming framework with a model of computation based on tasks and resources and that stipulates a timing semantics. Typically, hard real-time requirements are a characteristic of safety-critical applications. In contrast to runtime verification, such applications primarily require static assurances concerning safety and security attributes. This thesis discusses the building blocks for a statically analyzable programming paradigm for embedded real-time applications and its implementation. Svenska kraftnät funded the research presented in this thesis and set the scope to industrial automation. Consequently, we also investigate the applicability of our RTFM framework for scheduling and resource management for the runtime environments of industrial applications. We start by reviewing relevant and well-established industry standards to build background knowledge of the state-of-the-art safety and security requirements in software development. Special attention is placed on the IEC 61131 and IEC 61499 standards for industrial software development and their programming and execution model. We show the feasibility of using IEC 61499 as a holistic, distributed, and hierarchical model with mappings from the functional layer (IEC 61499 function block networks) and safety layer (PLCopen safety function blocks) to RTFM. We also demonstrate that our Rust-based RTFM implementation enables static verification for a myriad of safety and security attributes. Moreover, our investigations reveal a mutual dependency of safety and security in the context of software systems. For this reason, we believe and argue that safety and security cannot be considered independent during the design and implementation of safety-critical applications. Upon closer examination, we even conclude that safety and security are equivalent.
