Hello,
we have seen in the sourceforge repository that 13 days ago Florian
Pose fixed an error that caused the slaves not going to OP. We have
downloaded the last Etheract Master version 1.5 from the repository
and now everything seems to work properly...
So, my question is, is this version "good" enough to make some
tests/applications with Ethercat or it is still in a very early version?
Thank you very much!

We have also tried connecting only the EL2004 Digital Output module and
connecting only the EL4132 Analog Output module and decreasing sample
frequency to 50 Hz and the "erratic" behavior doesn't change, sometimes
the modules get to the OP state and sometimes not.
Thank you for your help!
Quoting "Dr.-Ing. Wilhelm Hagemeister" <[email protected]>:
Hello Jordi,
this is a unknown behavior...
please supply:
- Kernel version
- Ethercat version
- Network card
- Output of "ethercat master" (without running your sample program)
- Output of "ethercat slaves" (without running your sample program)
- Sample time of your sample program
try your sample program with only one module and at a slow sample rate
and with a different network adapter
Regards Wilhelm.

Hello everybody,
as nobody is answering to my colleague's question, I've thought that
maybe his explanation is difficult to understand, so I'll try to explain
it in a clearer way.
Our problem is that we have modified the mini.c example module to fit
our modules: EK1101, EL4132, EL3102, EL2004. After compiling the module
without errors, when we insmod it, we find that sometimes some modules
get to the OP state and some others remain at the PREOP state or
continuously changing among INIT, SAFEOP, PREOP, ... states. Everytime
we insmod the mini module, the ethercat modules that really get the OP
state are different, so it seems a random behavior.
