This paper proposes a formal representation of logic controllers programs that is aiming at improving scalability of model-checking techniques, when verifying controllers extrinsic properties. This representation includes only the states which are meaningful for properties proof and minimizes the number of variables that feature each state. Comparison with previously proposed representations, on the basis of three increasing complexity examples, validates this representation and quantifies its efficiency.
