<p>Hi,</p>
<p><br>
</p>
<p>I originally had this problem with the amps I use so I created a patch to add a
<span style="font-family: Calibri, Arial, Helvetica, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
ecrt_master_deactivate_slaves()</span> function.</p>
<p><br>
</p>
<p>When shutting down my application I call ecrt_master_deactivate_slaves() and continue realtime polling until (masterState.al_states == 0x02). I can then exit realtime and call ecrt_master_deactivate().</p>
<p><br>
</p>
<p>I'm not sure if that part of my patch got picked up by etherlab or Gavin's patch set (see etherlab-dev forum).</p>
<p><br>
</p>
<p>I've attached the patch file I currently use. You could extract out the bit you need. (Note: I use and patch against etherlabmaster 1.5.2 2526.)</p>
<p><br>
</p>
<p><br>
</p>
<p>Regards,</p>
<p>Graeme.</p>

<div class="PlainText">Hello,<br>
<br>
When I quit my application by calling ec_master_deactivate, this causes an error of watchdog on the EL7211 slave.
<br>
<br>
If prior to quit my app I use the command line tool to do an 'ethercat states PREOP', I get rid of the problem, but this function is not available in ecrt.h.
<br>
<br>
Is it the right method ?<br>
<br>
