All language subtitles for 2. Analog output - how to measure voltage

Let's begin with analog outputs.

So I have my list here and here I haven't got analog outputs what I should dorm.

I should see a model here or signal but I have a signal vault.

So it does not look out for one on the look out of that as a resolution off 12 beats.

So take the rock and roll drop and bought this place as you will see after it.

I can click here and go to properties and see what I have exactly here.

Here you see that we have got Channel zero.

So the Shenandoah for example is for the voltage or current output.

If I changed the column you see that the current rate is far from zero to 20 million amps and voltage

it is plus minus 10 volts.

So I chose the voltage output.

It is everything from the side.

Second think what you should know at all is to know which address will pass exactly of this model for

measuring these value.

We need that integer value or so it is what we need to bytes.

So it started at the byde a D and Ds and is at 81.

So you have to remember these values the most important is this first value because we have to start

our cure that you're d in order to have this full range of measurements.

So after days we can come back to our program and prepare that program.

But first of all I have to explain your how we recalculate the values from these Mandola to our normal

values.

First of all I would like to show you why we have this strange number of deranged twenty seven thousand

six hundred forty eight.

Why you'll see here.

Our own output representation.

It is for the voltage as you see that for the voltage is zero.

It is it's taken a scale between decimal our decimal system to all the voltage.

If you will know our model can measure from plus or minus 10 volts for minus 10 a volt we have got this

right.

So we're short.

Right.

We should work in this range because it is our as you see right.

Right.

We can also narrow some moral higher values of the voltage it is over short range and we can measure

these values so they're just a value can measure it is in the of these numbers.

And in the voltage it is eleven point seventy six votes.

If we have such higher voltage We have got overflow and our daughter beings to have some.

And we cannot measure the voltage.

But in this range we have we can have some net worse resolution or accuracy exactly the same it is from

the mindless side of the voltage.

So now go to our equations and here we have got our equations as we remember we have this value of the

maximum value.

It is twenty seven thousand six hundred forty eight and it is for 10 volt if we want for example measure

not exactly measure but put some voltage on the out with and we want half the value of six volts.

We have to put some value in the same model.

So how we can calculate it directly from the proportions so X is exactly equal the value of the maximal

range multiplied by our value which we want to have by divided by the maximum the range of our model.

So as you will see after these recalculation we short paused here in D.C. sixteen thousand five hundred

eighty eight point eight.

But your if you remember that we put only the integer values because it is Dabur it is worth.

So we have to port and that these arrests of this value and port here.

This is enough for our accuracy.

So come back to the program and start programming so being that we can though if our lock out model

is for some output voltage this model how we can make it we use for it watching for a stable home.

So in online moët you can read out here our address if you remember for my case it was a team our display

format chores email plus minus because our my mother has exactly plus minus 10 Covault And here we modify

it.

This value can be of course from this model from plus or minus or from mine plus twenty seven thousand

six hundred forty eight.

So for example if you want obtain some value on the out of the model Please write some volume for example.

Right the maximum value twenty seven hundred twenty seven thousand six hundred forty eight.

And after this please click this lightening.

Next if you want see if you have got exactly this voltage on your model on the vote please contact all

your people see volt meter.

According to specification which show wiring diagram.

So once again come back to this diagram.

In my case it is a signal board and as you see here we have got exactly these outputs in my signal board.

If you have got signal model it to look similar you'll have to call Negat volt meter from the zero to

all that.

Come on by DS for example black cable or their volt meter and cable.

Please connect all these out with zero because the zero means that it is exect the first channel of

these people see.

So if your value of 10 volts your Euro program works go out.

For example if you want uptime for example six volts as you remember from this equation which I showed

you.

So please write sixteen thousand five hundred eighty eight.

And when you make it please send it to KLC and checked on your volt meter.

If you have got 6 volt I have got so we can go out there in our program.

Now we have to write some program which will send out a Motty click and recalculate the value which

we would like to have on the out.

So first being which we have to make.

We have to implement our equation.

How we can do it by my function and this very nice block of the calculation.

First thing I have to say that on the output you'll have to obtain integer value because our analog

output it does the word output so you will have to have the value exactly in that war state as you see.

If we put a value in that integer we can Porth only integer values so from zero to 10 so it is only

10 values for example 11 will be also OK and also for the minus side.

It's also is but we want for example the value of 6 commodify volts so how we can make it we can doit

only by their operations.

We have all true serial operations.

We will have to port here to free imports as we remember from our equation and I will port here.

Their value is first of all the value of twenty seven hundred six went to seven thousand six hundred

forty eight.

And it is our 2.0 because it will be really valuable here.

We will support our M.D zero where we will put our value on which we want to have and please rename

the stack.

It is for example outport in voltage.

So here we port which we want like half voltage on the output and the first value it is 10 volts so

the maximum range of this where our model so that equation in our case it is in one reply by inport

tool and this error think.

Divide by input free after each we can not write here.

Exactly.

Could that be you.

Because it is integer.

So we have to save it in some other variable and defer.

And we have to rename the stack.

And for example we had a temporary temporary attack because we have to once again it convert.

So if you remember I also showed some conversion

conversion blocks and how it will works.

It will change.

They're very valuable to integer value.

We will have our and the for.

So our 10 for our value which we have here obtained and on the output will will support our acute WATB

because it is our Mandola we can name 8 that it does not look out for.

For example zero because it is our first outport okay.

It is everything.

Now please don't load this program to that you'll see and you'll see how it will exactly works.

After all alone.

Please monitor the blocks.

First of all we have got the values of zero.

So your volt meter now short display exactly zero zero vault and we can modify this operand and right

for example Tricom my fi vault.

Please click OK here you will see some strange values of the calculation because it is scaling back

proportionately according to our equation the output and these output is next converted by some processors

of this block to from there really out of value.

So we create delete does that.

And it does in our case around it up according to maté Monte-Carlo goals.

So you'll see that on the output you have on the Volt Meter freq on my 5 volts.

If you modify it once again these value you can right for example six Gama'a eighty five volts and it

is called Ding.

It is about these volume.

So it is everything about an hour analog output controlling in voltage.
