pulse Intel steps up support for industrial control designs Intel has made a number of introductions around its Intelligent Systems Framework (ISF) including framework-ready products and two new software tools intended to support designers in the industrial market. One specific development is that of a PROFINET IO solution based on the Intel Ethernet Controller I210 and stacks from KW-Software, that achieves the highest level of PROFINET performance. The most common design practice has been to implement the PROFINET interface in an ASSP or an FPGA, Intel says; this development allows the Intel’s System Studio development environment generates a cycle-by-cycle plot of predicted power demand against program flow, to reveal where coding generates highest energy usage. function to be brought into a standard chipset. At the same time, Intel is releasing two new software tools – System Studio and the Firmware Support Package – to support ISF. System Studio integrates multiple development tools into a single package aimed at embedded and mobile software developers using Intel processors and SoCs. System Studio includes system and application debuggers, a memory and thread error checker and tools to optimise code for power efficiency (figure) and performance. The Firmware Support Package provides low-level Intel CPU, Intel chipset and memory firmware initialisation capability using a standardised interface. Previous firmware solutions for embedded devices were, Intel says, highly customised and offered no backward compatibility: you can integrate the Firmware Support Package into any boot loader of the your choice, such as coreboot, Wind River VxWorks, BIOS, Real- Time Operating Systems, Linux and open source firmware. The Intel System Studio single user licence is available for $3,499 and a floating license (one seat) is available for $5,299. The Firmware Support Package and the Intel Intelligent Systems Framework are available free of charge. - by Graham Prophet Intel, www.intel.com Design RS485 links with assured EMC protection Analog Devices has collaborated with Bourns – as a supplier of circuit protection devices – to offer what both companies claim is the first RS485 evaluation board with Certified RS-485 EMC performance. The challenge of matching the EMC characteristics of external protection devices and the components they are designed to protect is, ADI asserts, among the biggest contributors to schedule and cost overruns for manufacturers of industrial and instrumentation equipment. As the externally-certified, EMC-compliant design tool for RS- 485 circuits, the EVAL-CN0313-SDPZ board provides design and integration files, device drivers, and evaluation hardware that you can import directly into a target project. The EVALCN0313 SDPZ also includes an EI3 Hirose connector that allows the board to be used with ADI’s ezLINX iCoupler Isolated Interface Development Environment, giving you a plug-andplay method to evaluate the digitally-isolated RS-485 physical communication layer. The board incorporates ADI’s ADM3485E, 3.3-V RS-485 transceiver and various circuit protection devices from Bourns and meets IEC61000-4-2/4/5 ESD (electro-static discharge), EFT (electronically-fast transients), and power-surge specifications. Specifically, the board offers line protection against 6-kV, 4-kV and 1-kV surges (IEC61000-4-5); 2-kV EFT and 8-kV contact (IEC61000-4-4); and 15-kV air-discharge ESD (IEC61000-4-2). It comes in ADI’s “Circuits from the Lab” reference circuits library and includes circuit notes, test data and results that you can apply to applications such as motor controls, mains-connected inverters, and programmable-logic controllers. The development board will cost $78: there will be a webcast on March 27th 2013, details at; www.analog.com/ RS485EMC-Webcast There is a video clip at; www.analog.com/RS485emc - by Graham Prophet Analog Devices, www.analog.com/RS485emc w ww.edn-europe.com MARCH 2013 | EDN Europe 13
