<div class="markdown_content"><p>Hello<br/> I can't find anything to read on the subject so I'll ask here.<br/> Up to now, when adding a (for example) Modbus Master, I've selected the version &lt;= the RT version, so if I'm using SP13 Patch 3, I can use a library that doesn't exceed this.<br/> I've no idea if this is correct, but it's always worked.<br/> Can someone explain the 4.x.x.x libraries that have appeared; are they tied to a RT version?</p> <p>The controller I use is now at SP18Patch60, so should I continue to use 3.5.xxx or change?</p> <p>thanks</p></div>
