<![CDATA[Alarm list and update]]>Hi all
I have some problems i am new in Mango, if someone can help me, i want to perform a simple thing but i cant do it.
I have a data source with a list of data point (binary). I want to show in a GUI "only" the one that is alarmed in realtime, mean value=true. and fill a table with that..

This code that i am testing, Does not work property does not show in realtime, i change manually the value to test and no row is show in a table.

When i manually update the page, appear a row but not in realtime.

<ma-point-query query="{$and: true, deviceName:'Menerga Faults', name:''}" limit="30" points="puntos_faults"></ma-point-query>
<ma-point-values points="puntos_faults" values="combined_faults" latest="1" from="dateBar.from" to="dateBar.to" rollup="{{dateBar.rollupType}}" rendered="true" rollup-interval="{{dateBar.rollupIntervals}} {{dateBar.rollupIntervalPeriod}}">
</ma-point-values>

<div id="3a040097-4b4d-46c7-bcc4-1bb62d4563e8" style="position: absolute; left: 590px; top: 937px; border-width: medium; border-style: solid; border-radius: 10px; border-color: rgb(153, 153, 153); width: 485px; height: 165px;">

<table class="customTable">
  <thead>
    <tr>
      <th>Current Faults</th>
      <th>Value</th>
    </tr>
  </thead>
  <tbody>
    <tr ng-repeat="punto in puntos_faults" ng-if="combined_faults[0]['value_' + punto.xid + '_rendered'] == 'true'">
        <td>{{punto.name}}</td>
        <td style="color: red" ng-repeat="value in combined_faults">{{value['value_' + punto.xid + '_rendered']}}</td>
    </tr>
 
  </tbody>
</table>

Thanks you very much for the help.

If they are not updating in realtime, then you have other problems.

Thanks :)

  1. Don't make too many changes in one go. You will only confuse yourself.
  2. move that ma-get-point-value inside the loop. Make it focus on only one point rather than many.
  3. Have you tried echoing out the points themselves onto the page, just to make sure all of the data you need is there?

It is possible to change ma-point-value to ma-get-point-value ? but this last one does not have realtime option.

<ma-point-query query="{$and: true, deviceName:'Menerga Alarms', name:''}" limit="30" points="puntos"></ma-point-query>

<ma-get-point-value points="puntos"></ma-get-point-value>

<div id="f18b7537-6b27-406b-9d2c-48daa56b3ff0" style="position: absolute; left: 21px; top: 922px; border-width: medium; border-style: solid; border-radius: 10px; border-color: rgb(153, 153, 153); width: 485px; height: 165px;">

<table class="customTable">
  <thead>
    <tr>
      <th>Current Alarms</th>
      <th>Value</th>
    </tr>
  </thead>
  <tbody>
    <tr ng-repeat="punto in puntos" ng-show="punto.value">
        <td>{{punto.name}}</td>
        <td style="color: red">{{punto.renderedValue}}</td>
    </tr>
    
  </tbody>
</table>

Thanks so much again.

Another small question, how i can get the value of a list of datapoints, i have to use ma-point-query with ma-point-value ? there is a way to have a list of datapoints and made a ng-repeat="point in points" then point.value?

You can use ma-point-query, or the ma-watchlist-table, look at the examples on the menu. Turn on the api docs via aministration->edit menu and save. You will find it very beneficial.

Looks pretty good, change the 'true' to true, you're comparing booleans not strings.
Secondly, for better speed, change those ng-if statements to ng-show. You want it to be dynamic and only show if the value is valid, hide if invalid. ng-if will mess with this as it will have to re-render the elements every time your values are true.

Also, I removed from="dateBar.from" to="dateBar.to"
You don't need these if you are pulling the latest, which brings me to the next thing. If you want to pull the latest value, use realtime="true"
This is why it isn't updating automatically for you.

<ma-point-query query="{$and: true, deviceName:'Menerga Alarms', name:''}" limit="30" points="puntos"></ma-point-query>

<ma-get-point-value points="puntos"></ma-get-point-value>

<div id="f18b7537-6b27-406b-9d2c-48daa56b3ff0" style="position: absolute; left: 21px; top: 922px; border-width: medium; border-style: solid; border-radius: 10px; border-color: rgb(153, 153, 153); width: 485px; height: 165px;">

<table class="customTable">
  <thead>
    <tr>
      <th>Current Alarms</th>
      <th>Value</th>
    </tr>
  </thead>
  <tbody>
    <tr ng-repeat="punto in puntos" ng-if="punto.renderedValue == true">
        <td>{{punto.name}}</td>
        <td style="color: red">{{punto.renderedValue}}</td>
    </tr>
    
  </tbody>
</table>

This work ok, but not in realtime, i changed the data point but the table is not updating with a new row, only when manualy reload the page. Also when i change back the data point does not remove the row :(. again only reloading the page. works.

Thanks.
