<div class="markdown_content"><p>I'm looking for a smart and short way to implement initialization of visualization variables <strong>depending on the visualization input</strong>.</p> <p>For an easy example consider a rectangle which rests at XPos := 0 when the input state is false and at XPos := 50 when the input stat is true. My visualization variables look like this:</p> <div class="codehilite"><pre><span></span><code><span class="n">VAR_IN_OUT</span> <span class="n">State</span> <span class="p">:</span> <span class="n">BOOL</span><span class="p">;</span> <span class="n">END_VAR</span> <span class="kr">VAR</span> <span class="n">XPos</span> <span class="p">:</span> <span class="n">INT</span><span class="p">;</span> <span class="n">END_VAR</span> </code></pre></div> <p>I put this rectangle via a visualization frame element into another visualization and link a frame reference variable with the state to it.</p> <p>If the variable is true, the rectangle should rest at XPos := 50 and false at XPos := 0 at visualization init but how should I assign the 50 or 0 to the internal visualization variable XPos? I would need some init-methode for the visualization but I dont want a global init-method for such tasks. I want to do it inside of the visualization element but I can't see any solution for this? </p> <p>It would be good to be able to define ST-code within the visualization element which runs cyclic at each VISU_TASK task-cycle then I could just check the input state and change the XPos accordingly. </p> <p>Does someone have a solution?</p></div>
