Initially, the stack is for the RZ/T2M servo motor control MCU and the RZ/N2L industrial internet gateway MCU.
Binary versions are available for evaluation, and licenses for commercial come directly from Renesas.
“The stack is Renesas’ first certified software that supports Profinet IRT and Profidrive,” according to the company. “IRT ensures precise and time-sensitive [Ethernet] data transfer, making it ideal for real-time applications such as servo drives and motion control systems. “We are delighted to have integrated the Siemens’ IRT device development kit on our devices.”
The stack included Profinet RT (real-time) communication, supporting cyclic data exchange with a Profinet IO controller. It 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,” said Renesas. “Furthermore, it includes fast start-up functionality, shared device support, MRP [media redundancy] and S2 [system redundancy].”
Profidrive provides a standard data exchange format for parameters including speed, torque and position between automation systems and: variable speed drives, servo motors and other motion control devices.
“Renesas implemented a certified Profidrive application example for Application Class 4,” it said. “This includes the implementation of a drive object with a speed set-point 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.”
