<div class="markdown_content"><p>modifying subject for more clarity , from so long waiting period i found no body is going to respond to me. Its really very serious issue for me. Please mark your views,</p> <p>Dear All,</p> <p>First of all thank for admin to allow my entry in this forum.</p> <p>I am user of CoDeSys V3.5 SP3 Patch4,<br/> We are using codesys for DCS controller programming.<br/> System structure are as below <br/> 2 Redundant controller as a Master and Profibus / Modbus slaves are connected to controller.<br/> Controller Redundant pair is having fix address ( 0075 &amp; 0076).<br/> Problem: When i am scanning controller from (Device--&gt; Communication System --&gt; Gateway-1) <br/> (Case1--&gt; When computer is not connected to any network) Scanned controller address will be shown as per configured address in controller as 0075 or 0076 , which ever is present.<br/> (Case2--&gt; When computer is connected to any network) Scanned controller address will be shown as 0000.082F.B075 or 0000.082F.B076 , which ever is present.<br/> Also this case address will change in run time without resetting controller or without any power recycle condition.</p> <p>I want to fix scanned controller address as per configured only, even if computer is in network or not gateway should show the 0075 /0076 address only.</p> <p>Please suggest configuration.<br/> Please do needful.<br/> Thanks,<br/> T Deshmukh</p></div>
