Secure web access over PROFINET Renesas Electronics Europe and Sevenstax joined their forces to commercialize a secure connectivity solution for industrial automation applications, that supports secure web access using standard internet protocols over a PROFINET communication. The secure connectivity solution is based on: Renesas’ PROFINET IO Device Chip TPS-1 supporting PROFINET IRT (isochronous real time); and the RX630 Group of microcontrollers (MCUs) as a host device. The provided software framework for the RX630 Group contains a software library to interface the PROFINET hardware and an IoT stack to implement common internet protocols such as a webserver and an AJAX/JSON API for the web application. The web application for the solution is based on Sevenstaz’s Webdesktop framework and can be stored in the MCUs’ internal flash or in external flash memory. A comprehensive demo firmware is available showing the interaction between the web application and Renesas’ PROFINET IRT – TPS-1 solution kit, combining an evaluation board with software. The webserver is protected with secure user authentication including an extensive user & group management. Further protocols and services, e.g. TLS, IPv6, secure Firmware-Update and even additional fieldbus protocols are available as RX630 Group compatible software packages. Renesas Electronics Europe www.renesas.eu Transparent connector integrates LED to help troubleshooting TE Connectivity’s Detector connector is an extension of the reliable and time-tested DEUTSCH DT connector series. The 2 way plug features a transparent housing and a wedge-lock with an integrated 12 or 24 volt LED option. The environmentally sealed Detector plug provides a visual confirmation of power to help with troubleshooting, especially in areas with difficult connector visibility and accessibility. The connector accepts all size 16 DEUTSCH contacts, solid or stamped & formed. It comes with colour coded wedge-locks for operating voltages, 12VDC (yellow) and 24VDC (red) and joint retention fingers allow both contacts to be removed at the same time. Protected to IP67, IP6K9K when used with back-shells, the connectors are compatible with pulse width modulated control, they are rated for operation in a temperature range of -55 to +125°C, with a contact current rating of 13A. Flammability rating is UL94-V0 for the housing material and UL94-HB for the seal material. TE Connectivity www.te.com FTDI Chip releases X-Chip breakout boards for USB 2.0 bridging FTDI Chip has introduced an array of new breakout boards, simplifying the bridging of USB 2.0 (full speed) signals to serial or parallel interfaces based on its X-Chip series USB 2.0 chips. The UMFT200XD is a USB-to-I2C module with 4 control bus lines, which is based on the FT200XD device. The UMFT201XB incorporates an FT201XQ IC and is also designed for USB-to-I2C conversion. This is complemented by the UMFT220XB, featuring a FT220XQ, which enables conversion of USB to a user-chosen, parallel bit interface (FTDI Chip’s own proprietary FT1248 I/O) where the data bus may be set to a bit width of 1, 2, 4 or 8 depending on design constraints. The UMFT230XB modules relies on a FT230XQ USB-to-UART IC. It has 4 control bus lines and can be utilised for UART bridging with a UART rate of 3Mbit/s available. These modules are powered via USB, with no additional power source required. They do not have a built-in USB connector as the mechanical dimensions of the PCB allow direct insertion into the USB Host connector. In addition to the standard -01 products, the new X-Chip breakout boards will also be offered in 2 other versions. The -NC variant is supplied without the connector on the I/O side, while the -WE variant comes with 15cm ‘flying leads’ attached. Each of these X-Chip breakout boards is suitable for use with a broad range of different operating systems. These include Windows CE.NET/Vista/7/8/XP/XP Embedded, as well as Android, Linux 3.0 (and above) and MAC OS-X.
