What term describes the values calculated by PLCs that represent the performance of a production system?

The term that best describes the values calculated by Programmable Logic Controllers (PLCs) to represent the performance of a production system is performance indicators. These indicators serve as quantifiable measures that help evaluate the effectiveness and efficiency of various processes within the production system. They provide insights into how well the production is functioning by reflecting various aspects of productivity, quality, and operational efficiency.

Performance indicators can include metrics such as production rates, downtime, and equipment effectiveness, which are essential for process optimization and decision-making. This information helps organizations identify areas for improvement, ensure consistency, and align production goals with business objectives.

While productivity metrics, production statistics, and efficiency rates may relate to performance measurement, they do not encompass the broader range of metrics used to evaluate overall performance as effectively as performance indicators do. Thus, performance indicators present a comprehensive view of how a production system is performing.
