Experimenting with Ethercat.
Connecting three devices it work perfect. But with more there are cases
then only some messages arrive back to master and some cases there no
messages arrive back to master. Even though message do not arrive back
as expected checking with broadcast write message arrive at last device
and probing with oscilloscope I could see data is sent on Ethernet cable
back towards computer. No sign of other communication problems except
what I am pretty sure is ordinary Ethernet messages destroyed on purpose
by nodes.
Anyone else here have any experience with Ethercat?
