It seems like the position on the slave network doesn't matter. What matters i the alias addressing of this particular slave. When I don't give the TU4 slave any alias address I can power-cycle it without loosing it. But as soon as I've given it an alias address
and power-cycle it is lost (not every time but almost).</div>

What might cause this? It seems like the EEPROM/Sii of the slave overwritten at start-up when it has been given an alias address. Is there a way to prevent this? How does this work "under the hood"?</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
I use "sudo ethercat -p1 alias 2" for example to give the slave on position 1 the alias address 2. Nothing wrong here I presume since it seems to work for other slaves.<br>

I've been in contact with the vendor of the TU4 module and they claim that this module is working in big volumes (thousands) on the market. All their other customers use TwinCAT and they haven't heard of this problem. I have also tried three different TU4 modules
to exclude the possibility of one failing individual.<br>

<p class="x_MsoNormal"><span style="font-size:12.0pt; color:black">I loose contact with my TU4-ECT (freq inverter from Nord Drive) slave after power-cycling it when there are other slaves on the bus. This happens intermittently. Only a EEPROM reset (I use TwinCAT
for this ) can make it accessible again. When it is the only slave on the bus it seems as I can power-cycle and always access again.</span></p>
