Implementing a "Remote Front Panel" using the webserver

Versatile and affordable operator interfaces

Mosaic's embedded computers combined with displays and touchscreen operated graphical user interfaces (GUI) offer a low cost solution to instrument control. Our HMI products are ideal for numerous OEM applications that require a programmable hand-held controller and a smart user interface. A touch panel display; a powerful microcontroller; Ethernet or WiFi connectivity; sophisticated gui tools for programming hundreds of screens; compact flash mass memory; and many flavors of expandable I/O will make your system more flexible and efficient without compromising its affordability.

Remote front panel made possible with affordable expansion modules

Mosaic controllers offer a touchscreen-based "Graphical User Interface" (GUI) that enables a user to control the instrument by pressing buttons and menus on the screen. The software that runs the GUI is called the "GUI Toolkit" and is available as a pre-coded "kernel extension" library from Mosaic Industries.

An EtherSmart or WiFi Wildcard can be added to a touchscreen-based controller to implement a web-based "Remote Front Panel" that allows a user to operate the unit via a web browser. Your instrument connects directly to a LAN, and through its router and firewall to the web, enabling you to view and manipulate the instrument's GUI from any standard web browser. A replica of the GUI screen can be presented in the browser window on a remote PC that will enable mouse clicks to mimic the action of touches on the instrument's touchscreen. The browser displays a bitmapped image of the GUI screen exactly as it appears on the controller's LCD (Liquid Crystal Display). Clicking on the web-based image with a mouse has the same effect as touching a button on the touchscreen: both the local screen image and the web image are updated.

Use of the remote front panel feature can expand the capabilities of an instrument, offering the possibility of web-based remote control, reporting, and diagnostics via an Ethernet or WiFi connection. You can remotely control the instrument or process, download data, or adjust control parameters with a remote front panel.

Source code generator makes front panel design easy

Ideal for scientific instruments, robotics, or process control, our affordable embedded computers come with a set of complementary features including real time operating system software, and precoded device drivers. With the help of Mosaic's GUI Toolkit and the GUI Builder you can design hundreds of screens with different levels of graphical user interface - from simple switchboards to sophisticated diagrams of entire processes. And you don't have to worry about the source code, the GUI Builder helps generate it for you.
