Human-Maschine-Interfaces HMI

A reliable and intuitive solution is needed at the interface between the operator and the automatic flatness control system. The newly developed GRIP-HMI (Human-Machine-Interface) meets exactly these requirements.

All important information is shown on the display and the cooling system can be operated via touch screen.

The GRIP-HMI is available in two versions, which can be ordered individually or as a complete package:

OCS: The cooling system can be controlled via a permanently installed touch panel.

WCS: With a wireless tablet the maintenance mode can be controlled and allows valve tests to be performed directly in front of the rolling mill. This significantly reduces the amount of personnel required for maintenance work.


Your advantages with the GRIP-HMI
The GRIP HMI systems are programmed on customer request and can be retrofitted on all existing GRIP systems. Smaller cooling systems can be visualized as well as complex cooling zone arrangements. We always find a solution to display the cooling systems well structured.

Users find their way around the GRIP-HMI quickly and operate the system intuitively right from the start, without the need for extensive training. The displays on the screens are based on the latest findings in material design. This ensures that users can see at first glance what the current status of each cooling zone is and can intervene if necessary.

Additional signals and information that are helpful to the operator can be displayed on the HMI interfaces. For example, depending on the configuration of the cooling system, the temperature and pressure of the cooling medium can also be neatly integrated into the visualization.

  • Retrofittable – can be adapted for existing cooling systems

  • Customized control – is programmed for the specific plant

  • Closed network – meets highest security requirements

  • Dark mode – for eye-friendly operation

  • Uncluttered design – the most important information is immediately visible

HMI – Overview of basic functions

Mode Description
Automatic mode The HMI panel displays the current status of the valves. It is visible at first glance whether a zone is activated or deactivated. In this mode, users can only monitor and not switch valves.
Manual mode The signals of the automatic flatness control are still displayed. The valves are also switched on and off accordingly. The users can now interact. Individual zones can be activated and deactivated at any time.
Maintenance mode In this mode a zone can be manually activated and deactivated. This allows users to switch individual valves during maintenance in order to check the function and spraying behavior.
Spray test In the built-in spray test, all zones are activated one after the other. Depending on the configuration of the cooling system, an automatic fuse test is also possible. The system automatically checks whether one or more fuses are defective and displays them once the test run is complete.
Error signals Error signals existing in the controller are integrated in the visualization. Examples of this are: Pressure drop, fuse alarm, power supply interruption, etc.

The feature set can be extended and adapted according to customer requirements

OCS – Operator Control System

The Operator Control System is intended for permanent installation in the control center. Depending on customer requirements, the zones are visualized on one or more screens. All displays are touch-screens and thus allow uncomplicated control by the user. All the above mentioned operating modes are available on the fix installed OCS touch panel.

WCS – Wireless Control System

The “Wireless Control System” is WiFi-controlled and designed for maximum freedom in terms of testing and maintenance activities.
The wireless panel can be removed from the operator’s control room and allows valve testing and maintenance activities directly in front of the rolling mill. The WCS is limited to maintenance and test mode and is not designed for automatic and manual mode.

For the connection, a local, strictly internal WiFi network is established between the OCS panel and the WCS tablet. This WiFi connection is used exclusively for communication between the controls. For security reasons, access to the public Internet or another network is absolutely impossible.
