As embedded computers have become ubiquitous, so too the need for human machine interfaces has grown. Now small form factor HMIs appear headed for inclusion in nearly every part of human existence.
Red Lion's latest addition to the G3 series of operator interfaces is the G315C touchscreen. The G315C offers a 15" TFT active matrix 32K colour XVGA 1024 x 768 pixel LCD and a 10-button keypad for on-screen menus.
The PV series from MyTek is an HMI equipped for various applications. Display sizes from 3.7 to 12.1" are available, and it can be used with most popular programmable logic controllers, inverters, temperature controller etc. With a rugged plastic housing and IP65-rated front panel, the PV series can be used in most harsh environments. The hardware features include a built-in ethernet port, a USB port, a serial interface, a parallel interface, a CF slot, real-time clock and an optional Profibus extension port. The HMI comes with a touch or keypad type screen and consists of a 32 bit RISC processor with the option of a CCFL backlight/LED backlight/Colour TFT LCD screen.

The crucial benefit of basing control and monitoring on web technology is that an HMI application for an automation device only has to be edited once. It can then be called from all Windows PCs, PDAs and Saia Web panels. This saves duplication of expenditure and, with that, a lot of time.
The Delta Electronics DOP-A and AE series HMIs are now available from Mechtric electric and mechanical engineering products. The DOP series are available in a wide range of screen types and sizes ranging from 3.8" blue screen to 10" 64K colour screen.
The Mitsubishi Electric GT1155-QSBD is a 256-colours compact graphic operation terminal for controlling factory-automated machinery.
C-more touch panels from Automation Direct are fully programmable and provide power and flexibility. The panel displays are available in either greyscale (15 shades of grey) or full colour (256 to 64,536 colours, depending on model). STN greyscale and colour displays are available in a 6" touch screen. Colour TFT touch screens are available in 6, 8, 10, 12 or 15" versions.
The A&D Mercury AD4820 is an HMI and PLC measurement and control system all rolled into one complete compact package. The instrument runs a 32 bit RISC processor and uses a real-time operating system, RT Linux. The AD4820 utilises a GUI front end known as virtual console (VC), together with a PLC ladder for controlling all I/O known as measurement and control ladder (MC).
