Efficient Handling of States in Abstract Interpretation of Industrial Programmable Logic Controller Code. |

This paper presents an efficient static analysis for programmable logic controller code. For each program line (or each function block call), the analysis calculates an over-approximation of the possible values each variable can assume during all possible executions. This information can then be used to automatically check for certain critical program conditions such as division-by-zero and array-out-of-bounds. To make this approach applicable to large programs comprising many variables, we present a technique that only stores the values of a subset of the variables based on their context and liveness. We show how to detect typical problems in real PLC code. |
