[etherlab-users] Beckhoff EL6224 IO-Link

[Rehberger, Sebastian]

Hello,

thanks for the hints. Unfortunately I did not get the IO Link clamp to run with just the SDO configuration and I guess this isn't possible for this kind of configurable clamps. 

However a viable way to work around was to pre-configure the EL6224 with TwinCAT and write the config (created with an .iodd device description from the end point RFID sensor) to the the clamp. Afterwards the PDO configuration derived by --skin etherlab looks completely different, but can be now used to retrieve the sensor information from the specific device. 

The configuration steps in TwinCAT/config mode  have to be repeated after a restart of the clamp, which is a bit of a pitty (I guess IOLink commands are sent to set the sensor device to OP). I guess it would not very easy to implement the configuration into Simulink, but I'll leave it for now.

Best regards,
Sebastian

Hallo,

copy the output of etherlab --skin etherlab -p xx to your m-file.
Add sdo configuration as show in attached example.
Call the m-file from an generic slave block.

Attached an example for EL7041.

Sometimes one has to examine the configuration from TwinCat.

Regards Wilhelm.
