HMI Touch Panel

HMI Touch Panel or Graphical user interfaces enable the display of machine data and the control of machine processes. The operator can monitor data via the graphic interface. Different states can be highlighted in colour. With the touch function and graphically displayed switches and buttons, the operator sends commands to the machine. Hmi touch panels can be used as PLC display extensions. Product variants with digital and analogue inputs and outputs can be used as stand-alone controllers.

Display size




HMI Touch Panel for industrial applications in many variants. All EMKO proop control panels have USB, RS232 and RS485 interfaces as standard. Equipped with an ARM Cortex-A Series processor, 512 MB RAM and 4 GB, even complex graphics, videos and processes can be displayed.

Display properties of the HMI touch panel

The EMKO PROOP series display has a very fast vector-based graphic display with powerful Cortex A series CPU. For design creation, the Builder software (Figure 1) provides a user-friendly design for quick and easy development of the user interface and control and switching functions.

Application examples HMI Touch Panel

The panels act as an interface between the user and the machine and can be used as a PLC display extension or as a stand-alone control. The graphics of the display can be created individually. Animated buttons and switches enable the output of commands. Furthermore, animations and videos can be played, for example, to show processes or to provide instructions on how to operate the machine.
The panels are compatible with common PLC communication protocols from Siemens, Omron and Delta. This enables the connection to existing systems. The integrated interface transmits the data via cable connection or Wi-Fi.
The resistive display is suitable for industrial environments and also allows operation with gloves.
