Renesas, SEVENSTAX Team Up for Secure PROFINET for IIoT

As the factory floor and various devices and applications become more connected through Ethernet-based automation systems and the Industrial Internet of Things (IIoT), security becomes an even greater issue for manufacturers. To that end, Renesas Electronics Europe and SEVENSTAX have teamed up to provide a secure connectivity solution for PROFINET, the standard for industrial Ethernet, supporting secure Web access for industrial automation applications, according to Renesas.

Renesas is a supplier of advanced semiconductor solutions and SEVENSTAX provides embedded Internet protocol stacks and applications. The two companies demonstrated their solution, which 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, late last year.

The solution’s 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 Web server and an AJAX/JSON API for the Web application, according to Renesas. That Web app is based on SEVENSTAX's Webdesktop framework and can be stored in the MCUs’ internal Flash or in external Flash memory.

To help manufacturers understand how the two companies’ products interact for secure connectivity, the companies also provide a demo firmware showing the interaction between the Web application and Renesas’ PROFINET IRT-TPS-1 solution kit, combining an evaluation board with software, according to Renesas.

The solution works by protecting the Web server with secure user authentication, including an extensive user and group management, the company said. Further protocols and services, such as TLS, IPv6, secure Firmware-Update and even additional fieldbus protocols, also are available as RX630 Group compatible software packages.

Renesas designed its PROFINET IO Device Chip TPS-1 as an integrated, single-chip solution for simplified and cost-efficient implementation of PROFINET IRT interfaces for automation devices. It also features configurable host interfaces that allow for deployment flexibility, such as direct connection of an external host CPU or digital I/Os without additional circuitry, the company said.

Manufacturers also have flexibility of choice for the RX630 Group aspect of the application, which has six Flash memory capacities and eight package variations, according to Renesas. All the devices of the product set include E2 data Flash capable of 100,000 rewrites, and enhanced peripheral functions with increased numbers of channels including timers; USB 2.0 function module,; a multichannel serial communication interface and a I2C bus interface; CAN; and a 10-bit and 12-bit A/D converter as well as a 10-bit D/A converter.

Other built-in features of the RX630 Group include RTC with timestamp, a temperature sensor, an independent watchdog timer, and power-on reset and low-voltage detection controller. These enable manufacturers to reduce the number of external parts used in the solution, according to Renesas.
