HMI module targets renewable energy

Aug 10, 2009 — by Eric Brown — from the LinuxDevices Archive — 3 views

German embedded firm SSV announced a touchscreen control unit designed for HMI industrial applications. The EUI/57V is equipped with an x86-based Vortex86DX processor clocked to 800MHz, a 5.7-inch VGA touchscreen, and HMI (human machine interface) connections that include Ethernet, serial, USB, CAN, GPIO, and SPI, SSV says.

The EUI/57V touchscreen control unit is built around a BB6/eSOM baseboard containing SSV's eSOM/2586 computer module, which uses a proprietary form factor the company calls "eSOM-200." In addition to providing common computer interfaces, eSOM-200 modules offer a generic 16-bit bus that can support a wide range of peripheral modules, says SSV. The module's 200 pins are said to be accessible on two FX8C plug connectors.

Introduced earlier this year, SSV's first eSOM-200 module is the eSOM/2586 (pictured below), which, like the company's DIL/NetPC DNP/2486 computer-on-module (COM), runs Debian Linux on an x86-compatible Vortex SoC from DMP Electronics. However, the eSOM/2586 runs the more powerful Vortex86DX instead of the older 300MHz Vortex86SX.

Announced last November, the Vortex86DX is a 32-bit x86 SoC that targets home gateways, thin clients, and industrial controllers. Claimed to run Linux using under two Watts, the Vortex86DX puts a CPU core, northbridge/southbridge, and numerous peripheral functions into a single IC housing.

SSV clocks the EUI/57V's Vortex86DX to 800MHz, and backs it up with 128MB DDR2 SDRAM and a gigabyte of NAND flash containing the Debian-based embedded Linux distribution. Storage expansion is available via a CompactFlash slot.

The 5.7-inch TFT LCD touchscreen offers VGA resolution and a 4-wire-touchscreen interface, says SSV. The module is said to provide interfaces including 10/100Mbps Ethernet, USB 2.0 host interfaces with 480Mbps support, dual RS232 ports , and an RS485 port. Additional interfaces include CAN, GPIO , and SPI.

All interfaces are integrated into the preinstalled software and can be used directly from Java, says SSV. The pre-installed software includes X-Server, as well as the original Sun Java Runtime Environment (Java 6 J2SE), says SSV. The software bundle also includes the Java 6 with Swing widget toolkit and API, which enables the development of independent graphical user interfaces (GUIs) with a procedural (Java- and Swing-based) or declarative (HTML- or XML-based) approach, says the company.

The pre-installed software can be extended with integrated data logger, teleservice router, and virtual IP modem functions, says the company. The EUI/57V is particularly suitable for front-panel systems used in renewable energy applications, where data must be logged over long periods, and "a safe remote maintenance access is standard," says SSV. Extended temperature versions of the device are also said to be available.
