Hello, in this tutorial, we will take a look, wants to the application once more than proportional
and integral and true with to control method of the fifties or temperature or cooling systems and anything.
What was the idea?
Imagine this is your own end of output like that.
OK, with the idea what we are doing, we have a set value, OK?
And like that, the set value was increasing higher and lower and down like that.
But with the API algorithms it was just adapting itself and then it was keeping our set value and present
value.
It was done in this, uh, video tutorial.
This is just an explanation we had.
We FTL, we F.T. OK, Delta, we FDL and we have.
OK, and this is 28 a we, but we will use a sweet two or three to model of Delta p.l.c. and potential
mate and what is the application basics?
You need to listen to this, listen carefully, and then you can understand the next tutorial, the
next application tutorial.
Very well.
OK, we have a plus from my, uh, to my potential mater and we have a minus.
OK, and then we have analog input and this analog input is going to go to connect it to my wafty why
we are using a potential meter because of imagine this is your.
Pipe, OK, into pipe, there is an air pressure, OK, and this air pressure is between zero to 10.
Well, imagine it like that.
And you are reading this analog volume.
And according to this analog volume, you are sending a material to this pipe, OK?
Or you are stopping or you are increasing or decreasing your VDT speeds than, let's say here a motor.
OK, this motor is turning fast or or decreasing its speed, then the material is going inside to pipe
very less or more, according to this, air pressure is changing and we are reading it with the policy.
And now I don't have any analog to digital converter because of this.
We will use this port.
This port is connected to my VTE and we will read this portfolio zero to 10 volt value via.
Communication, OK, arise from the need for communication.
We will read this potential meet value of this parameter, this VDT parameter and that parameter is
zero zero point zero for this parameter is can be selected by users.
And which data is selected into this parameter of Delta V FTL?
And then you can read user defined area into several communication arrays.
Four hundred and eighty five communication.
If you read user defined um parameter and it was we can take a look once two thousand one hundred and
two I guess.
No not this one two thousand one hundred twelve.
And I'm going to check once.
Is it here.
This is my PID document.
OK, and this is not a correct one.
OK, so now um we can go back to Microsoft whiteboards.
It doesn't matter.
We will use this parameter for the user defined parameter for the communication that we are getting,
this potential method, analog value.
This is the first thing.
And the second thing we need is to, um, define or create.
Serial communication between my p.l.c. and VTI, so we here are four hundred and eighty five communication
and just two cable to here and let's go here like that, OK?
One is plus and minus and.
This is mine and this is plus and then what are we going to do?
We will write to Wafty Run or six months.
We are at four hundred eighty five communication and we will get the potential mental value.
And also the in other words, from the Vivia communication, OK, this is the fully set up of the control.
And then let's go to document in here.
Um, we can check once a little bit in into here.
You will see the parameters, these parameters of the um, the sampling time, OK.
And the proportional gain, an internal gain and derivative gain and other control modes and the things
that we're going to take a look once into this p.l.c. program.
OK, this is, uh, taking a long, long time.
And because of this, I created this program for you.
And we will go inside this p.l.c. program one by one, and we will see how my p.l.c. is affecting to
or how my PID is affecting to output according to our analog input from the potential meter.
See you in the next florea.
