Advanced Process Control (APC)

The APC library offers a large selection of sophisticated control functions and is integrated directly into the SIMATIC PCS 7 control system.

The APC functions can be divided into the following three classes:

• Control Performance Management
  For monitoring the control quality and optimizing control loops.
• Extension to PID regulation
  Contains APL approaches that can be implemented by skillfully combining PID controllers with other function blocks.
• Multi-size control (Model Predictive Control)
  Includes tasks with regard to subsystems that have several mutually influencing control variables.

Condition Monitoring Library (CML)

The blocks of the SIMATIC PCS 7 Condition Monitoring Library enable cost-effective monitoring and analysis of mechanical assets (system components such as pumps, valves, heat exchangers) with the aim of increasing their efficiency and availability and recognizing any damage at an early stage.

Advanced Process Graphics (APG)

APG is another library for more effective process control. It is an HMI concept for optimized process monitoring and control. Instead of just displaying data, APG offers task and goal-oriented information such as hybrid displays, trend curves or Kiviat diagrams. All key performance indicators (KPIs) are also visualized. Situations can be correctly assessed even faster, which leads to further advantages:

• Safer decisions
• Less misuse
• Higher product quality
