[etherlab-users] Created scicoslab block

[Andreas Stewering-Bone]

Hello Simone,

The EtherCOS has no generic block in the actual version
and it does not support SOE and DC, so no chance to get the AX5101 running

If you have a running C-Example you only have to port it to a C-Function 
Block


- write a C-Function block (see ethercat user space example), please 
note you can only use 1 EtherCAT Slave per EtherCAT Master.
- you have to store the master and domain, and variable handles in the 
work vector
- you have to add the soe parameters
- write a calc in/out function to connect the channels to the ethercat io

and that is all.

I think you will try the compilation step, a problem could be the 
linking of the ethercat lib.

Greatings
