rotation absent gauge engine

[lh777]

I tried to model a gauge EPR compared to the value of N1.
Unfortunately, after several tests and modifications not working. Can you help me figure out what is wrong? I'm trying to be more than 6 months .........

els{ (L:Epr, number) 348.98 * 331.65 - (>L:N1_Value, number) }

Potential problems:

No space in (L:Epr, number) 1.164 &lt;= between &lt; and =
Lines like - <Rotate> should perhaps not have a - at the start.
If the command (>L:N1_Value, number) removes that value from the stack (I don't know this), then there is no value left in the <Value> statement. If so, then you would need to add a (L:N1_Value, number) just before the </Value> statement. Unless you need to use this L: variable somewhere else, there is no reason to store the Value in there.

I may be wrong, often am when it comes to gauge coding, yet I was under the impression <= didn't work. It isn't listed in the SDK.

Maybe try...

(L:Epr, number) 1.165 <

cheers,

&lt;= is a proper XML operator for less than or equal to.

You are right that the XML parser objects to a "<" used in an operator. It expects that what follows is tag name like <Element>. The parser doesn't have the same objection to the use of ">", which works for greater than, and to write an L:Var, (>L:Variable, number).

In my opinion, it's a best practice to write &lt; for less than and &gt; for greater than, just for the sake of consistency.

My question is, where is (L:Epr, number) getting a value? There is no sim variable (A:simvar,unit) anywhere in your script.

You need to provide a duplicated (L:Epr, number) value in line 6 for the Nonlinearity table to work with. Play with this:-

<Gauge Name="testepr" Version="3.1" Author="Edward Cook">

    <Image Name="ENG_NDbak.bmp" ImageSizes="154,154"/>  (* Just for testing *)

  <Element>
      <Position X="72" Y="72"/>

    <Image Name="ENG_ND.bmp" Luminous="Yes"  ImageSizes="78,16">
      <Axis X="11" Y="8" />
    </Image>
   <Rotate>
     <Value Minimum="1.0" Maximum="1.8">
     (L:Epr, number) d 1.164 &lt;=      (* duplicate Epr to get a value to read *)
         if{ (L:Epr, number) 69.091 * 5.7273 - (>L:N1_Value, number) }
         els{ (L:Epr, number) 348.98 * 331.65 - (>L:N1_Value, number) }
     </Value>
     <Nonlinearity>
        <Item Value="1.0" X="9" Y="43" />
        <Item Value="1.1" X="30" Y="19" />
        <Item Value="1.2" X="59" Y="5" />
        <Item Value="1.3" X="91" Y="5" />
        <Item Value="1.4" X="117" Y="14" />
        <Item Value="1.5" X="138" Y="37" />
        <Item Value="1.6" X="148" Y="67" />
        <Item Value="1.7" X="144" Y="96" />
        <Item Value="1.8" X="130" Y="121" />
     </Nonlinearity>
   </Rotate>
  </Element>

<Mouse>   (* Just for testing *)
   <Tooltip>eprNo> (%((L:Epr, number))%!2.2f!)%</Tooltip>
    <Cursor Type="Hand" />
  <Click Repeat="Yes">(L:Epr, number) 0.01 + 1 max 1.8 min (>L:Epr, number)</Click>
</Mouse>

</Gauge>

Hope this helps, Ted.
