<div class="markdown_content"><p>Hello,</p> <p>Thank you for your answer.</p> <p>I'm afraid I was not clear on what I was trying to achieve.</p> <p>I'm trying to change parameters and command axes from inside a function block and the first thing that came to my mind was pass both the EtherCAT slave and axis to the function block (as image attached). But, I believe it's worse than just pass directly the EtherCAT slave address to the function block (is it???). However I was wondering if there was a way to get the EtherCAT address directly from the axis, so I don't need to pass the EtherCAT slave nor the EtherCAT address to the function block.</p> <p>Thank you again!</p></div>

<div class="markdown_content"><p>Hello<br/> SDO will write to the drive, not the axis, so you need to pass in the etherct slave:</p> <p><strong>VAR_IN_OUT<br/> Axis: IoDrvEthercatLib.ETCSlave;<br/> END_VAR</strong></p> <p>Then you can get the address with:</p> <p><strong>Axis.PhysSlaveAddr</strong> (as UINT)</p></div>

<div class="markdown_content"><p>Hello,</p> <p>I'd like to write some parameters to axes from inside a function block where I passed axis by reference, using ETC_CO_SdoWrite. Is it possible to get the device address from inside the function block?</p> <p>Please see example below.</p> <p>Thank you!</p></div>
