<div class="markdown_content"><p>Hi,</p> <p>I think so using an array of <span>[ * ]</span> elements as input.<br/> The mainnidea is to have 1 to n elements as input this way.</p> <p>Within the FB you should loop over the 1..n elements using a FOR loop or something.<br/> be sure to read help onnthis topic for further hints on using this mechanism.</p></div>

<div class="markdown_content"><p>My requirement is that the number of input/output parameters to the FB should be a variable and when instantiating the FB, the required number of parameters can be specified. So one instance of the FB can have 2 IOs, another can have 10 etc. Thanks!</p></div>
