The Advanced Process Library (APL) is the standard library of SIMATIC PCS 7 for performing automation and process control tasks. It is based on many years of experience of configuration engineers and plant operators and takes into consideration current NAMUR recommendations and PNO specifications.
Channel blocks for standard signals (e.g., Analog In, Analog Out, Digital In, Digital Out) and for fieldbus signals
Blocks for integrating drives and motor management starters (e.g., SIMOCODE or SINAMICS)
Technological function blocks such as motors, valves, measured values, controllers, operator control blocks, counters, interlocks, etc.
Advanced closed-loop control functions – Advanced Process Control (APC) such as Gain Scheduler, PID Tuner, Smith Predictor, or Model Predictive Controls
Maintenance blocks for alarm suppression and maintenance alarms
System blocks such as for manipulated variable/coefficient calculation or conversion blocks
Logic blocks (analog, binary, mathematical functions)
Block icons and faceplates for visualization and for operator control and monitoring
The function blocks allow easy and fast engineering. The signal status is thereby consistently tracked together with the value of a signal. Information about the quality of the represented value is available at any time via displays on the operator station. The faceplates are adapted to the requirements of the operating personnel, which not only enables optimum process operation but also a good overview of the plant status. With these user-oriented APC functions, demanding APC applications can be implemented easily and cost-effectively in small and medium-sized plants.
