<p class="MsoNormal">Hello everybody,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-US">I want to change the value for the watchdog at ESC register 0x0420/0x0421. This is easily done by specifying<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">in the corresponding XML-file for the slave.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">When using TwinCat with this new XML-file the new value is automatically transferred to the slave ESC-register when TwinCat scans the bus and I actually see a watchdog with a 5 second timeout.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">As we are using Etherlab Ethercat Master instead of TwinCat I would like to save this changed value in the EEPROM on the slave.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I tried to write the EEPROM using TwinCat, did a power-reset, but the changed value was either not written to the EEPROM or not read out by the ESC…the watchdog time has not changed and remains at the default 100ms.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The EtherCat Knowledge Base at the ETG web site states that ESI and SII both supply the same information about a slave.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">So what am I doing wrong? Is TwinCat not writing the EEPROM correctly? Is it generally not possible to write this configuration information to the slave EEPROM?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I hope somebody can help.<o:p></o:p></span></p>
