Short Desciption:
This manual will help you when selecting, configuring, and assigning parameters to a controller block for your control task. The manual introduces you to the functions of the configuration tool and explains how you use it.

Summary:
The software product ”Standard PID Control” essentially consists of two function blocks (FBs) which contain the algorithms for generating control and signal-processing functions for continuous or step controllers. It is a pure software control in which a standard function block incorporates the functionality of the controller. The behavior of the controller itself and the properties of the functions in the measuring and adjusting channel are realized or simulated by means of the numberic algorithms of the function block. The data required for these cyclic calculations are saved in control-loop-specific data blocks. An FB is only required once to create several controllers. Every controller is represented by an instance DB which must be created application-specifically. When the ”Standard PID Control Tool” is used, this DB is created ’implicitly. This means that the design of a specific controller is limited to specifying the structural and value parameters in the editing windows of the user interface. The instance DB is created by the configuration tool. The calculation of the algorithms for a certain controller is carried out in the processor of the S7 automation system (AS) in the set time intervals (sampling times). The calculation results and thus the updated values of the input and output variables (measuring and manipulated variables) and status signals (limits) are stored in the corresponding instance DB or transferred to the process periphery. In order to process several control loops which are to be executed at different intervals – but equidistantly – depending on the inertia of the respective process, a controller call distribution function (Loop Scheduler = LP_SCHED) is available through which the configuration of extensive plant controls becomes structured and thus simple. In addition, even utilization of the CPU is ensured.
