2.3Operator 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 system (Human Machine Interface) represents the interface between the human being (operator) and the process (machine/system). The controller actually controls the process. That is, there is an interface between the operator and WinCC (on the HMI device) and an interface between WinCC and the controller.

WinCC is the software to handle all necessary configuring tasks. WinCC Advanced V11 Simulation is the software for process visualization.

WinCC handles the following tasks:

•Representing the process

The process is mapped to 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 use a graphic user interface to operate the process. The operator, for example, can 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 older production data can later be accessed.

•Documenting process values and alarms

Alarms and process values can be read out by the HMI system as a log. After a shift, for example, you can have the production data read out.

•Managing process parameters and machine parameters

The HMI system is able to store parameters for processes and machines in recipes. These parameters can, for example, be transferred from the HMI device to the controller in one step in order to change production to another product type.
