Hello,
Can somebody explain me how I can estimate the Master Tx Rate based on
the list of exchanged PDO's with the slaves (an all other related
things). I tried to compute it based on the structure of an Ethernet
frame but I never found the good value. I don't found a consistent rule
that fit different examples. For instance, I have two programs with the
first exchanging 26 Bytes of PDOS and the second 40 Bytes. Both are
running at 1kHz (communication rate with the slave). With the first I
have a Tx rate of 60.5 kByte/s and for the second 69.8 kBytes. Thus a
difference around 9.3 kBytes/s although I have, in practice, 14 kBytes/s
more to exchange (14 x 1000). I though first to the 1024 conversion for
the Byte, but the difference is bigger.
As anybody more information about that ?
Thank you
Pierre Letier
