An ultra-compact design doesn’t have to mean limitations in terms of functionality. DISPLAY VISIONS demonstrates this with its touch operating units in theEA-HMI series. Even at diagonal screen measurements of just 2.8″ and 4.3″, these displays offer excellent functionality in the smallest space. They thereforerepresent a robust solution for all industrial applications where compact dimensions are a real issue.
The EA-HMI operating devices can be used with more than 20 widely available programmable logic controllers (PLCs), including the models from well knownproviders such as Allen Bradley, Beckhoff, Mitsubishi and Siemens. They are configured as slaves and support the standard communication protocols ModbusRTU and Modbus TCP.
In addition to the compact dimensions, another highlight of this series is the ease of integration into existing PLC systems. The displays support all data types,including coil, discrete, input and holding. It is also possible to process 32-bit floating point values for floating point calculations. The data elements, from thetext and numbers to the bar graphics and images, can be assigned flexibly to the Modbus registers.
The free of charge software HMI designer is available for customers to develop their own user interfaces quickly and easily. This WYSIWYG tool allows screenpages to be designed intuitively. After the interface is designed, the Modbus registers are logically linked with the display elements, which means that thecorresponding data is automatically shown on the display in a form that is always up to date. DISPLAY VISIONS also offers the creation of complete,customer-specific HMI designs as a service on request.
The EA-HMI series operating units offer a high level of brightness of 1000 cd/m², which means that the displays can be read at all times, in poor lightconditions or even outdoors. The devices are intended for wall or front panel assembly.
