<div class="markdown_content"><p>Hi All,</p> <p>I am hardly looking for a way to “customize” Modbus offsets in a Modbus Serial Device Object.<br/> Here my Codesys device is Modbus serial slave.</p> <p>The problem that I’m experiencing is that there is no available field dedicated to set the Modbus offsets in the mapping table.<br/> I know that it is possible in devices such as Eurotherm LIN instruments for example, for those who know these!<br/> In these devices, we are able to define modbus offsets without any consideration of the function code, reading or writing access.</p> <p>Is there a way to do that in Codesys devices ?<br/> In other words, I would like to be able to put an input register at the offset 723 in the modbus serial device mapping table, even if it is the only register.</p> <p>Thanks for your help!</p> <p>Fred.</p> <p><img alt="IMG: image007.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=2477"/></p></div>
