Operating Panels with PCT Technology
Attractive human-machine interface: the ETT multi-touch series
Young, powerful, attractive ... the ETT multi-touch operating panels from SIGMATEK are looking for a challenging range of tasks in a modern machine concept.
With the ETT series, SIGMATEK launches operating panels that optimally combine multi-touch functionality in hard and software. The modern HMIs enable new, smart operating concepts that provide positive operating experience and conveys "zeitgeist".
Equipped with an ARM-based EDGE2 Technology dual-core processor, the ETT panels provide high performance (2x 800 MHz) with low power usage. 512 MB of DDR RAM for internal program and data memory, 512-MB storage (microSD) for data logging, recipe and alarm management are also standard functions, as well as a 2D and 3D graphics accelerator. Even with graphically complex operating surfaces, the ETTs are in their element.
In the new SIGMATEK HMIs, projective capacitive touch technology (PCT) is used, by which the sensors are protected on the back of the robust, solid glass surface (IP65 protection). Multi-finger input, as well as the use of styluses and thin gloves are possible. For now, there are five ETT display sizes: 8.4 – 10.4 – 12.1 – 15 and 19-inch in classic 4:3 format.
The thinly constructed panels – with only a 48 mm installation depth – can be mounted directly on the machine, an operating console or integrated into the control cabinet and are therewith suited for the most varying areas of use. The interfaces are particularly selected, so that the HMIs fit in any machine and equipment configuration: 2x Ethernet, 1x CAN, 2x USB 2.0 and 1x USB OTG (On-the-Go). 8 digital in and outputs each are also on board, which can be used for command and signaling devices such as toggle switches, signal towers and operating mode switches. All connections are located on the bottom, which simplifies installation and maintenance. The ETTs operate without a fan. Reliability, robustness and electromagnetic compatibility (EMC) are essential properties of the SIGMATEK HMIs. The integrated 4 mm glass surface is completely dust-tight and easy to clean.
Logo backlighting with added value
Externally, the ETT multi-touch panels have a modern simple frameless design. A back-lightable logo gives the new panel series that special touch. The monochrome logo backlighting can be controlled via the application in any color (RGB). The ETT can therefore be perfectly integrated into the corporate design of the machine or equipment. The logo also lights when the touch screen goes into idle mode. An application-specific function can be created to make the backlit logo blink or display in a different color when an error occurs – a distinguishing feature with added value.
The fitting software tool for HMI
In addition to the high performance of the panels, the efficiency of the visualization software is key factor. Only when hard and software interact perfectly, multi-touch is a fully integrated operating concept. The SIGMATEK panels are delivered with a Linux-based real-time operating system and the object-oriented development tool LASAL, which is well equipped for the creation of intuitive multi-touch applications.
