Hi Dirk
How do you see that they are wrong? Sorry, still a noob...
[ 8413.402490] EtherCAT ERROR 0-0: Failed to set SAFEOP state, slave
refused state change (PREOP + ERROR).
[ 8413.402734] EtherCAT ERROR 0-0: AL status message 0x001E: "Invalid
input configuration".
I did not configure them at all. I simply took the slave that was connected and
operational on our Acontis EtherCAT master and connected the CAT5 cable to the
Etherlab controller.
I had tried configuring it manually in Etherlab before but always ran into this
input configuration error.
Some masters (not ours) read the SII eeprom and autoconfigure the slaves
with their default. Then they work.
Our master requires the slave to be known _before_ the network starts.
There are pro's and con's with this concept:
con: no auto config (but see below)
pro: you can start the master *without* being connected and attach the
network later. That is why the master cannot rely on reading SII, hence
no autoconfig. You can't have both :(
I like the latter, it is more explicit than implicit (rule #2 in 'python
-c "import this"' ... and this is a good lecture), but the learning
curve is steeper.
So:
$ ethercat cstruct
and merge that into the example and you should be going.
Mit freundlichem Gruß
Richard Hacker
