    This article brings out some challenges in the process of defining the PL of a safety function implementation. One of these examines the use of different cabling schemes of the SRP/ CS and their effect on the PL evaluation. The challenges are highlighted using a generic example of a safety function relating to a mobile work machine where different technologies (electrical, hydraulic and pneumatic) can be utilized. The different principles and solutions for considering things in the evaluation of the PL are discussed in this article.
