SGD 43-A 4.3 PanelPilotACE Compatible Display

Transcription

1 is a 4.3 capacitive touch display designed for use with PanelPilotACE Design Studio, a free drag-and-drop style software package for rapid development of advanced user interfaces and panel meters. The is the first in a range of PanelPilotACE compatible displays and panel meters. The low-profile display features a 4.3 capacitive touch screen and an ARM Cortex A9 processor running embedded Linux. The display can be powered from either or a 5 to 3 d.c. supply and offers users a wealth of hardware interfaces which include four 6bit bi-polar analogue inputs (to a maximum of ±4 d.c.), eight digital input/output pins, two alarm outputs (maximum current sink 0mA) and four 8bit PWM outputs. Users program the display using the free PanelPilotACE Design Studio software which allows the creation of anything from simple meters and dials, through to advanced user interfaces with control elements.

2 PanelPilotACE Design Studio Making Industrial User Interface Design Simple The design software provides a number of building blocks which allow users to drag-and-drop elements onto the screen to quickly create advanced user interfaces. From background images to text elements, analogue style meters, touch screen navigation elements and even complex logic statements, users can build up multi-screen interfaces without needing to write a line of code. There is a library of pre-defined elements such as meters, buttons and switches, and users can create their own content by combining elements or importing graphics in a number of formats (including jpg, png, tif, bmp and gif). The software includes support for transparency and multiple layers. Hardware interfacing is similarly intuitive, with hardware elements being dragged into a function builder where associations with graphical elements (such as a needle on a meter) can be defined. Here users can determine scaling for analogue inputs, define alarm triggers, behaviours for digital inputs and outputs and configure PWM outputs. Previewing and Uploading Projects The software includes a Preview in Emulator function which emulates the hardware s inputs and outputs, allowing users to test their projects prior to upload. Projects are uploaded to the via a mini port. PanelPilotACE Design Studio is compatible with Windows XP (SP3), Vista, 7 and 8 and can be downloaded free from. Issue 09/04 B.S. Page of 0

There are two mounting methods: The first uses clips that protude from the plastic assembly and is suitable for panels between and 3mm (0.04 and 0. ) in thickness. The second method uses a rear mounting plastic bracket featuring grub screws for a more secure and adaptable fit. This second mounting method is suitable for panels between 0.5 and 4.0mm (0.0 and 0.5 ) in thickness. Issue 09/04 B.S. Page 3 of 0
