System Libraries

A modern process control system like SIMATIC PCS 7 makes standardised modular software functions for process control and visualisation available for procedural tasks. These ready-made and tested function blocks, faceplates and symbols together form the perfect basis for simple project planning and reliable process control. We make these basic elements available in demand-orientated libraries.


Improved overview and more intuitive user guidance system: SIMATIC PCS 7 library manages to make plant control even more efficient. For users the process tag browser displays a perfect list of all measuring points of one or more plant areas, forming the foundation for systematic plant optimizations. With the new Operator Trend View you can conveniently group trend curves. In doing this, the operator can obtain a clear overview of the progress of processes even faster, so he can monitor the plant even easier, and run processes optimally. Moreover, with SIMATIC PCS 7 library individual process tags can easily be taken from the process screen and summarized in groups. This compilation is helpful for various standard operation scenarios in which the operator can now keep an eye on important process values in a much clearer way.

Function blocks are standardized software modules that model process engineering equipment such as valves and motors in I&C terms. They form the starting point on the software side for controlling your plant and are made available in well-organized libraries for engineering tasks and for program-specific implementation.

The Advanced Process Library (APL) in SIMATIC PCS 7

  • is based on many years of experience of configuration engineers and plant operators.

  • takes into consideration current NAMUR recommendations and PNO specifications.

  • increases ease of use through new and improved functionalities.

  • facilitates and speeds up the interaction of the operator with the plant.

SIMATIC PCS 7 Advanced Process Graphics (APG)

  • offer plant operators more compact and simplified displays in overview screens.

  • enable predictive plant control.

  • support easy monitoring of quality-relevant process parameters through uniform operator control elements and hybrid displays.

  • ensure optimized operational sequences.

  • improve the efficiency of operators and the plant over the entire life cycle of the process control system.

In addition to these, other libraries are available that extend the control system in function-specific and industry-specific ways. For example:

  • Industry Library

  • Condition Monitoring Library

All libraries are compatible with one another, provide you with tailor-made functionalities, and contribute significantly toward standardizing your automation solution.
