<div class="markdown_content"><p>Hi,<br/> When I use an Array like yours : Myarray : ARRAY<span>[0..9]</span> OF INT;<br/> And I set 'Max. array index' to 2, I got 4 lines in the table.<br/> You can also :<br/> - use a variable (for example : diIndexAff) as 'Max. array index and It works dynamically.</p> <ul> <li>calulate the value of the variable like this :<br/> VAR<br/> diIndexAff:DINT;<br/> END_VAR<br/> (<em>Max value calculation minus 2</em>)<br/> diIndexAff:=UPPER_BOUND(Myarray,1)-2;</li> </ul> <p>I did not try with the second try (_array : ARRAY<span>[*]</span> OF INT;).</p> <p>Hoping to help you.<br/> BR.</p></div>

<div class="markdown_content"><p>Hi,<br/> I wonder if it is possible to make table with dynamic number of rows.<br/> Normally if I use as 'data array'</p> <div class="codehilite"><pre><span></span><span class="n">_array</span> <span class="o">:</span> <span class="n">ARRAY</span><span class="o">[</span><span class="mi">0</span><span class="o">..</span><span class="mi">9</span><span class="o">]</span> <span class="n">OF</span> <span class="n">INT</span><span class="o">;</span> </pre></div> <p>I will have table with 10 rows - always with 10 rows (unless I set 'Max. array index' to lower value)<br/> I want to make it more dynamic. I try:</p> <div class="codehilite"><pre><span></span><span class="n">_array</span> <span class="o">:</span> <span class="n">ARRAY</span><span class="o">[*]</span> <span class="n">OF</span> <span class="n">INT</span><span class="o">;</span> <span class="c1">//in VAR_IN_OUT declaration of Visualisation</span> <span class="n">_array</span> <span class="o">:</span> <span class="n">POINTER</span> <span class="n">TO</span> <span class="n">INT</span><span class="o">;</span> <span class="c1">//in VAR_IN_OUT declaration of Visualisation</span> </pre></div> <p>But I alway got only one row. I have tried to set 'Max. array index' to eg. 5,<br/> manually set column template -&gt; 'Text variable' set to '_array<span>[INDEX]</span>'. But it does not work unfortunately.</p> <p>Do you have any idea if it is possible? Or I can only use constant size tables?<br/> Thanks for your help.</p></div>
