OPERATOR CONTROL WITH WINCC FLEXIBLE
2.1 System
Description
Since processes are becoming more and more multi-layered and the demands on the functionality of
machines and plants are increasing, the operator needs a high-performance tool for controlling and
monitoring production plants. An HMI system (Human Machine Interface) represents the interface
between a human being (the operator) and the process (machine/plant). The controller actually
controls the process. That is, there are two interfaces: one between the operator and WinCC flexible
(at the operator panel), and another interface between WinCC flexible and the controller.
The WinCC flexible Engineering System is the software that is used to handle all required
configuring tasks. The WinCC flexible Edition determines which operator panels of the SIMATIC
HMI spectrum can be configured.
WinCC flexible Runtime is the software for process visualization. In runtime, the project is executed
in the process mode.

WinCC flexible Runtime is the software for process visualization. In runtime, the project is executed
in the process mode.
WinCC flexible performs the following tasks:
• Displaying the process
The process is mapped to the operator panel. If a status changes in the process, for example, the
display at the operator panel is updated.
• Operating the process
The operator can operate the process by means of the graphic operator interface. For example, the
operator can specify a setpoint for the controller, or start a motor.
• Reading out messages
If critical process states occur in the process, a message is triggered automatically; for example, if
the specified limit is exceeded.
• Archiving process values and messages
The HMI system can archive messages and process values. In this way, you can document the
process characteristics, and you can also access older production data later.
• Documenting process values and messages
The HMI system can read out messages and process values as protocol. Thus, you can have
production data read out after the end of a shift, for example.
• Managing process parameters and machine parameters
The HMI system can store parameters for processes and machines in recipes. With one operational
step, you can transfer these parameters from the operator panel to the controller, in order to change
production to another product variant.
