PROFINET-IRT and PROFIdrive software stack for Renesas MPUs
Renesas has launched its first certified PROFINET software stack for its RZ/T and RZ/N series of microprocessors (MPUs), which supports both PROFINET IRT (Isochronous Real-Time) and PROFIdrive.
The initial software versions are available for the RZ/T2M MPU, designed for servo motor control applications, and the RZ/N2L, for industrial internet gateway applications, such as remote-I/O or industrial Ethernet devices. Using Renesas MPUs with this software stack eases the path for certifying customers’ devices.
PROFINET is the leading industrial Ethernet protocol for automation systems and facilitates high-speed communication in industrial automation equipment. Its highest performance class, PROFINET IRT ensures precise and time-sensitive data transfer, making it ideal for real-time applications such as servo drives and motion control systems.
The implementation of the certified PROFINET IRT stack encompasses all essential features required in industrial equipment communication including PROFINET RT (Real-Time) communication. The software supports cyclic data exchange with a PROFINET I/O controller and can handle diagnostic, process, and status alarms, as well as plug and pull alarms. It assigns IP addresses and device names via PROFINET and through the device application. Furthermore, it includes fast startup functionality, shared device support, media redundancy (MRP), and system redundancy (S2).
“We expect the outstanding market success that we achieved with our RZ/T and RZ/N MPUs to further accelerate with the introduction of our network stack integration. PROFINET is the market-leading industrial protocol, and have integrated the Siemens PROFINET IRT Device Development Kit on our devices,” said Mohamed Dogar, Vice President of Embedded Processing Business Acceleration at Renesas.
“Our cooperation with Renesas has led to their first certified PROFINET IRT solutions using the Siemens PROFINET Device Development Kit,” said Efrossini Tsouchnika, Vice President Control at Siemens Digital Industries. “Industrial customers can now enjoy seamless integration options provided by Renesas within the PROFINET ecosystem.”
Simplified process to embed drive systems
PROFIdrive enables seamless integration of variable speed drives, servo motors, and other motion control devices into automation systems, ensuring efficient communication and operation. PROFIdrive standardizes data exchange between devices, providing key parameters such as speed, torque, and position, which are essential for precise control of drives. It supports both real-time communication through PROFINET IRT and conventional Ethernet, allowing flexibility in various industrial applications.
PROFIdrive profile on RZ/T and RZ/N MPUs
Renesas implemented a certified PROFIdrive application example for Application Class 4. This includes the implementation of a drive object with a speed setpoint interface. It supports cyclic data exchange via standard telegrams 1, 2, and 3, as well as acyclic data exchange through the PROFIdrive parameter channel. Additionally, the application encompasses PROFIdrive diagnostics and the state machine for the PROFIdrive General State Machine. It includes the PROFIdrive encoder channel with its respective encoder state machine and offers the simulation of a drive control system.
Binary versions of the PROFINET stack for the RZ/T2M and RZ/N2L MPUs are available on the Renesas website for evaluation. Customers can obtain licenses for commercial use directly from Renesas.
