1.4.2 Run-Time Software
Runtime software provides ready-to-use solutions you can call in user program and is directly
implemented in the automation solution. It includes:
Controllers for SIMATIC S7, for example, standard, modular and fuzzy logic control
Tools for linking the programmable controllers with Windows applications
A real-time operating system for SIMATIC M7
Controllers for SIMATIC S7
Standard PID Control allows you to integrate closed-loop controllers, pulse controllers, and
step controllers into the user program. The parameter assignment tool with integrated controller
setting allows you to set the controller up for optimum use in a very short time.
Modular PID Control comes into play if a simple PID controller is not sufficient to solve your
automation task. You can interconnect the included standard function blocks to create almost
any controller structure.
With Fuzzy Control you can create fuzzy logic systems. These systems are used if the
mathematical definition of processes is impossible or highly complex, if processes and
sequencers do not react as expected, if linearity errors occur and if, on the other hand,
information on the process is available.
