<div class="markdown_content"><p>For IF-THEN-ELSE:<br/> SEL is an idiomatic way, if (and only if) the two branches do not have side effects.<br/> An ugly way is using a chain of boxes each with EN/ENO.<br/> But please, even if you can write a FOR loop in Ladder, it does not mean it is a good idea. If you are unable to avoid side effects in branches, it is better to stay in ST: the resulting code will be more clear to others (including your future self).</p></div>

<div class="markdown_content"><p>Hi,<br/> First steps in codesys...<br/> Is there an equivalent to IF-Then-Else or Case in the FBD language? It seems to exist in the ST and I naively assume the you could do in FBD the same as in ST. <br/> thanks, J.</p></div>
