I just want to note that "raspi-profibus" is end-of-life and its successor "pyprofibus" is not split into Python and C anymore. It does not use an AtmelAVR via SPI for data transfer anymore. It's a pure Python implementation that already contains pure Python code for a /dev/ttyS UART PHY. So "pyprofibus" is not restricted to the Raspi and should work anywhere (including an LinuxCNC/awlsim enviromment. But that was not tested, yet) https://bues.ch/h/profibus https://bues.ch/h/awlsim https://bues.ch/h/pilc -- Michael
