Hi:<br><br>I am a new user of Ethercat device, and when I use BeckHoff EL3102
analog input device in an experiment (by following the example c code
in mini and RTAI of document "ethercat-1.4.0-rc3"), I find out that if
I keep the scan-cycle at 1 hz, I can access the Sdo data successfully, and read the value of analog in. However, if I put the Read_sdo() in a higher scan-cycle (e.g. 1000hz),
it always shows EC_SDO_REQUEST_BUSY status.<br><br>About two years ago, someone asked a question about read_sdo in realtime. At that time, the answer was No. Is that still the case now? If so, is there a way to read a value of analog_in in real time?<br>
<br>Thanks.<br clear="all"><br>Jason <br>
