<div class="markdown_content"><p>Hello jacobwago,<br/> I believe that the limit is fixed in the editor, but not in the driver package. There seems to be no link between the driver setting and the editor. Otherwise, I don't know why the input (&gt;10) is blocked, but the function is available. Unfortunately, I cannot offer you any other solution apart from the one mentioned above.<br/> Kind regards</p></div>

<div class="markdown_content"><p>Hello, </p> <p>I have experienced the same issue as described above but for the Modbus Serial configurator. Looking for a solution.</p> <p>In v3.5 SP19 Patch 7 the Modbus Serial Master Slave configurator has a "virtual" limit of 10 channels. In v3.5 SP18 Patch 5 this virtual limit does not exist. I can successfully copy back and forth from 18 to 19 with out any build error. However, this is not a good solution for our customers.</p> <p>Please help in providing a fix to the virtual channel limit of 10 in SP19.</p> <p>Thanks,</p></div>
