2.3 Operator control and monitoring with WinCC

System description

Since processes are becoming more and more multi-layered and the demands regarding the

functionality of machines and plants are rising, the operator needs a powerful tool to control and monitor

production systems. An HMI (Human Machine Interface) system represents the interface between the

human being (operator) and the process (machine/system). The controller has the actual control over

the process. There is an interface between the operator and WinCC (at the HMI panel) and an interface

between WinCC and the controller.

WinCC is the software that you use to handle all necessary configuration tasks. WinCC Advanced V11 is

the software for process visualization.

WinCC handles the following tasks:

• Representing the process

The process is represented on the HMI device. If, for example, a state changes in the process, the

display is updated on the HMI device.

• Operating the process

The operator can operate the process via the graphical user interface. The operator can, for example,

enter a setpoint for the controller or start a motor.

• Generating alarms

If critical process states occur in the process, an alarm is triggered automatically; for example, if a

specified limit is exceeded.

• Logging process values and alarms

The HMI system is able to log alarms and process values. Thus, the process can be documented and

you can still access older production data at a later time.

• Documenting process values and alarms

Alarms and process values can be read out by the HMI system as a log. For example, you can output

the production data at the end of a shift.

• Managing process parameters and machine parameters

The HMI system is able to store parameters for processes and machines in recipes. You can transfer

these parameters from the HMI panel to the controller, for example, in a single step in order to change

production to another product type.
