Secure web access over PROFINET
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.
