PROFIBUS Slave Stack for Renesas' R-IN Industrial Automation System

November 23, 2015 // By Graham Prophet
Renesas Electronics Europe and TMG TE have announced a PROFIBUS slave stack for the R-IN Family. The two companies are providing system solutions for Renesas' R-IN32M3 Series of industrial Ethernet communication application specific standard product (ASSP) and RZ/T1 Group of microprocessors (MPUs). A PROFIBUS slave implementation joins industrial Ethernet protocols.

There are over 50 million installed PROFIBUS devices in the process and manufacturing industries all over the world; "Although industrial Ethernet technologies have the highest growth rates within industrial automation, PROFIBUS continues to grow, adding 3.5 million new nodes worldwide in 2014 alone," said Niels Trapp, Senior Director Segment Solutions at the Industrial Communications Business Group with Renesas Electronics Europe. "This shows a significant customer demand that we are addressing together with our partner TMG TE. Our goal is to support our customers by offering rich software functionality and added-value services."

Renesas' R-IN Engine is an integrated processor subsystem that includes both Ethernet and RTOS hardware accelerators. It was specifically developed for industrial applications, where high speed and real-time communication as well as low power consumption are some of the highest priorities. The R-IN Engine is featured in the R-IN32M3 Series as well as the RZ/T1 Group.

The R-IN Engine runs PROFIBUS slave on an ARM Cortex-M3 processor with enough headroom to run additional applications. The integrated real time OS (HW-RTOS) reduces the burden of the CPU and improves the interrupt response time with minimal jitter. The combination of the CPU and the HW-RTOS results in ultra-high-speed real-time responsiveness five to ten times that of a conventional software real-time OS.

The R-IN Engine already supports a variety of industrial Ethernet communication standards, such as EtherCAT, CC-Link IE, EtherNet/IP, PROFINET and Modbus.

TMG TE is a service provider in industrial communication technology and focused on PROFINET, EtherNet/IP, PROFIBUS and IO-Link as well as TCI, FDT and EDD. TMG TE is member of PROFIBUS International, ODVA and the IO-Link community and is accredited as competence centre for PROFINET, PROFIBUS and IO-Link. TMG TE possesses own basic technology and has already realised various master and device integrations based its own or partners' technology;
