The software component Ethernet Device Driver for IRTE (EDDI) makes the industrial real-time Ethernet communication section of the relevant hardware (IRTE switch controller) accessible and therefore usable for IRTE based solutions. The IRTE switch controller functionality is independent of the OS and is also managed by PN Driver in conjunction with EDDI.
The system integrator interfaces are the input functions and output macros. Input functions are called directly by the system integration layer. Output macros are used within the EDDI and are implemented by PN Driver and PROFINET System Integration (PSI).
In combination with the hardware addresses provided in
EPS_PNDEV_OPEN_FCT, the EDDI can control the PROFINET Ethernet
Controller with integrated L2 Switch (IRTE-IP).
Note
The PNDevDriver must provide a set of parameters, memory areas and
functions in the structure EPS_BOARD_EDDI_TYPE.
Please refer to section Overview of sample PN Driver implementations for information regarding how EDDI is integrated to sample implementations to use the PROFINET Ethernet controller.
