<div class="markdown_content"><p>PD_Template , is this Schneider only or Codesys?</p> <p>How about interfaces and online change? E.g. an array of interfaces assigned different instances of the interface. It says somewhere in the manual that interfaces are realized using references.</p> <p>How does interfaces and references behave during an online change?</p></div>

<div class="markdown_content"><p>In soMachine from Schneider, using the library PD_Template, call the function block FB_DetectOnlineChange.</p> <p>Once this is done reassigning the pointers is easy using ADR() again.</p></div>

Could you share of how you're detecting online change and reassigning the pointers? Thanks</p></div>
