Small control systems with touch display

The slim PLC control of the DISPLAY VISIONS PLC series already has the touch display integrated. In addition, it can be wirelessly connected to up to 50 satellite displays. This allows processes to be monitored and controlled wherever they are.

Normally, the programming of small control systems and the reading out of their parameters is associated with some effort. Not so with DISPLAY VISIONS’ PLC series. The central control unit, also named as the “core”, has a coloured touch display already integrated in it. The brilliant 2.8-inch IPS panel is easy to read from almost any viewing angle (reading angle 170°) and even in direct sunlight. It’s not only able to display the measurement and process data, but also serves to input control commands and operating parameters thanks to its touch-sensitive surface. The core has eight digital inputs, 4 analogue inputs (4-20 mA and 0-10 V) and 4 relay outputs. It communicates via the RS‑485 or Ethernet interface and can also be accessed wirelessly via WiFi. Up to 50 satellite terminals can be automatically connected to the central control unit. Depending on the complexity of the input and output data, satellites with different display sizes are available, from the 1.5″ display with 240×240 pixels, which is just smaller than a postage stamp, to the 10.1″ panel with a resolution of 1,280×800 pixels. The satellites automatically synchronise with the core in real time and are individually configurable. For example, one point could be displaying operating data for the service, while one of the satellites at another point is used for work preparation and entering new parameters.

All touch and display functions can be programmed freely with the free Windows tool “PLC Designer” WYSIWYG. Numerous prefabricated elements support the construction of individual and even animated pages. The central control unit EA PLCC28 is designed for top hat rail mounting and is only 5 HP wide. There are various housings available for the satellite terminals for installation in other devices and for surface mounting.
