Toward multi-task support and security analyses in PLC program translation for verification: poster abstract

Published: 16 April 2019 Publication History

Abstract

In this poster, we will present new tool, HyPLC [30], which implements the translation of discrete control code of verified hybrid program models to PLC controller code and, vice versa, the translation of existing PLC code into the discrete control actions for a hybrid program given an additional input of the continuous dynamics of the system to be verified. This approach allows for the generation of real controller code while preserving, by compilation, the correctness of a valid and verified hybrid program. PLCs are common cyber-physical interfaces for safety-critical industrial control applications, and HyPLC serves as a pragmatic tool for bridging formal verification of complex cyber-physical systems at the algorithmic level of hybrid programs with the execution layer of concrete PLC implementations. This poster will also discuss future directions of HyPLC such as support of multiple tasks (and, by extension, multiple PLCs), interval arithmetic, as well as security analyses.
