The benefits of Advanced Process Control and advanced analytics have become increasingly well established in the process industry. Through continually evolving technologies, the benefits of APC are now accessible to a much broader range of industries and users by providing mainstream tools and leveraging diverse industry experience.

Recently, industry requirements of plant historian and HMI/SCADA products have grown, driven by pressure to reduce production costs, meet regulatory requirements and survive as competition increases. The challenge now is to meet the industry’s expectations to use these products to improve process optimization.

Transforming data into information

Many manufacturing and processing facilities have invested in historian technology, allowing them to capture large volumes of process information. These valuable repositories provide trends, reports and analyses from which companies make decisions about process performance. It is now necessary to have improved client tools that transform the captured data into actionable information.

When selecting Advanced Analytical tools for use with a historian and HMI/SCADA, the challenges to consider include:

  • Few intended users have an advanced statistics and modeling background

  • Analysis of historical data is not sufficient; knowledge extracted from data must be made actionable, preferably in the HMI/SCADA

  • To be really beneficial in an industrial context, a wide range of users should benefit from the Advanced Analytical tool, including operators, maintenance personnel, process engineers and other key operational employees

  • The ease at which Advanced Analytical tools connect and access data from a plant historian

  • How effective these tools are in enabling data preparation such as allowing for process lags and filtering out bad data and connecting to multiple data sources.
