    <p>This node implements the logic to control an electric shutter.<br/><br/>
    It can manage four different messages:
    <ul>
        <li>UP: command for opening (premitted values are SHORT, LONG, RELEASED)</li>
        <li>DOWN: command for closing (premitted values are SHORT, LONG, RELEASED)</li>
        <li>STATUS: message to update module status coming from motor (permitted values are STOP, UP, DOWN)</li>
        <li>POSITION: message to update shutter position</li>
    </ul><br/><br/>
    The outputs are:
    <ol>
        <li>STOP message used to stop the shutter at the current position</li>
        <li>POSITION message used to set the position target. this is a number between 0 and 100 where 0 is totally open and 100 is totally closed</li>
    </ol><br/><br/>
    Here the actuation logic:
    <table border=1 style="text-align:center">
        <tr>
            <th></th>
            <th style="padding-left: 3px; padding-right: 3px;">Same direction</th>
            <th style="padding-left: 3px; padding-right: 3px;">STOP</th>
            <th style="padding-left: 3px; padding-right: 3px;">Opposit direction</th>
        </tr>
        <tr>
            <th style="padding-left: 3px; padding-right: 3px;">SHORT</th>
            <td>STOP</td>
            <td>MOVE</td>
            <td>STOP</td>
        </tr>
        <tr>
            <th style="padding-left: 3px; padding-right: 3px;">LONG</th>
            <td/>
            <td>MOVE</td>
            <td>INVERT</td>
        </tr>
        <tr>
            <th style="padding-left: 3px; padding-right: 3px;">RELEASED</th>
            <td colspan=3>STOP</td>
        </tr>
    </table>
    </p>
