[etherlab-users] Station alias usage

[Michael Mangeng (V8tech)]

Hi!

The question is whether the EtherCAT-Master is using the Station-Alias 
Field internally to e.g. recognize slaves or anything else. If it does 
not use it, i will use it in my software.

Problem is the following:
E.g. Running ethercat-bus as building control bus with 10 slaves.
Now someone disconnects slave ID=3. Slave 4 is now 3, Slave 5 is now 4 
and so on. The building has to remain fully functionally (except of the 
disconnected slave of course).

I want to write a unique identifier into the station alias field of 
every registered slave so its not important at which position the slave is.

=> If the ethercat-master overrwrites the station alias field without my 
knowledge, i have to find another solution.

greetings from Austria,
Michael
