Setting Min/Max levels dynamically for tanks


  • Hello. I'm curious if there's a way to set the min and/or max attributes for the ma-tank-level object. Since the high level in my tank is dynamic depending on what it's being used for I'd like to be able to set the max level based on a point value. Is this possible? I've been playing with the dashboard designer for 2 days trying to figure out a way to make it work, but so far it eludes me. Thanks in advance!


  • Something like this will do the trick

    <div class="ma-designer-root" id="20dbb78c-92c3-4153-b4fd-4e281bf52ebb" style="width: 1366px; height: 768px; position: relative;">
        <ma-tank-level id="353257ad-8b4f-4a3f-bd56-199ec886a323" style="position: absolute; width: 378px; height: 372px; left: 113px; top: 101px;" point-xid="zero_to_hundred" max="tankCapacityPoint.value" min="0"></ma-tank-level>
        <ma-get-point-value id="efe64f60-a9eb-469d-9df7-62eae42bc730" style="position: absolute; left: 540px; top: 177px;" point-xid="tank_capacity_point_xid" point="tankCapacityPoint"></ma-get-point-value>
    </div>

    Thank you Jared. That's essentially what I have been trying (I think), with the exception that I'm using a point from the watch list instead of using the XID:

    <ma-tank-level id="d21fdc19-e1ab-40db-97fc-3a29c215a762" style="position: absolute; width: 200px; height: 200px; left: 165px; top: 344px;" point="designer.points | filter:{name:'CTD1'}:true | maFirst" min="0" options="" max="tankFillPoint.value"></ma-tank-level>
    <ma-get-point-value id="815edcc0-dda5-4daa-9952-e33f9c6ec0b5" style="position: absolute; left: 165px; top: 292px;" point="designer.points | filter:{name:'DS1'}:true | maFirst" points="tankFillPoint"></ma-get-point-value>
    

    The code I'm using essentially ignores the point value and uses 100 (the default value). Do I need to use the XID instead?

    Thanks, Andrew.


  • @ASwingler You are using the points attribute of <ma-get-point-value> wrong.

    I think what you are looking for is

    <ma-tank-level id="d21fdc19-e1ab-40db-97fc-3a29c215a762" style="position: absolute; width: 200px; height: 200px; left: 165px; top: 344px;" point="designer.points | filter:{name:'CTD1'}:true | maFirst" min="0" options="" max="(designer.points | filter:{name:'DS1'}:true | maFirst).value"></ma-tank-level>
    <ma-get-point-value id="815edcc0-dda5-4daa-9952-e33f9c6ec0b5" style="position: absolute; left: 165px; top: 292px;" point="designer.points | filter:{name:'DS1'}:true | maFirst"></ma-get-point-value>
    

  • Thank you - that was exactly what I needed.
