|

<p>Defines simple controls that modify links based on a single condition.<br />

</p>
|
|
<p><b>Format:</b></p>
|
|
<p>One line for each control which can be of the form:</p>

|
|
<p><b>   LINK</b> <em>linkID</em>   <em>status</em>  <b> AT CLOCKTIME</b> <em>clocktime</em>  <b> AM / PM</b></p>
|

|

|
<td><em>linkID</em></td><td>= </td><td> a link ID label </td></tr>
|
|
<tr>
|
|
<td><em>status</em></td><td>= </td><td> <b> OPEN / CLOSED</b>, a pump speed setting, or a control valve setting <br />

</td></tr>
|
|
<tr>
|
|
<td><em>nodeID</em></td><td>= </td><td> a node ID label </td></tr>
|
|
<tr>
|
|
<td><em>value</em></td><td>= </td><td> a pressure for a junction or a water level for a tank </td></tr>
|
|
<tr>
|
|
<td><em>time</em></td><td>= </td><td> a time since the start of the simulation in hours </td></tr>
|
|
<tr>

|
|
</table>
|
|
<p><b>Remarks:</b></p><ol type="1">
|
|
<li>Simple controls are used to change link status or settings based on tank water level, junction pressure, time into the simulation or time of day. <br />
|
|
</li>
|
|
<li>See the notes for the <a class="el" href="_status_page.html">[STATUS]</a> section for conventions used in specifying link status and setting, particularly for control valves. <br />
|
|
</li>
|
|
</ol>
|
|
<p><b>Examples:</b></p>
|
|
<p><code>[CONTROLS]<br />
|
|
;Close Link 12 if the level in Tank 23 exceeds 20 ft.<br />
|
|
LINK 12 CLOSED IF NODE 23 ABOVE 20</code></p>
|
|
<p><code>;Open Link 12 if the pressure at Node 130 is under 30 psi<br />
|
|
LINK 12 OPEN IF NODE 130 BELOW 30</code></p>
|
|
<p><code>;Pump PUMP02's speed is set to 1.5 at 16 hours into the simulation<br />
|
|
LINK PUMP02 1.5 AT TIME 16</code></p>
|
|
<p><code>;Link 12 is closed at 10 am and opened at 8 pm throughout the simulation<br />
|
|
LINK 12 CLOSED AT CLOCKTIME 10 AM<br />
|
|
LINK 12 OPEN AT CLOCKTIME 8 PM </code> </p>
