The advanced process library (APL) for version 8 is a database of controller function blocks [including advanced process control (APC)], variable frequency drives and other channel drivers, and graphic icons and faceplates. It is based on the many years of experience of project engineers and plant operators and takes into account the latest NAMUR recommendations and PNO specifications.

The APL features intuitive operator displays like the new loop preview window, which allows operators to see set point differences (internal versus external values) before making changes allowing them to anticipate the process response.   The APL faceplates are adapted to the needs of operating staff, allowing not only optimum operation of the process, but also a good overview of the system status. With these user-oriented APC functions, sophisticated APC applications for small and medium-sized installations are easy and cost-effective to implement. The optional industry library supports drivers for touch panels and the integration of Simatic S7 Package Units (AS 300 controllers) into Simatic PCS 7 applications.
