Hello young people I'm Professor REYNER, again I
meet on our platform youtube studio
let's learn together today we bring a new exercise for the module
automation I hope it's from of the taste of all of you
alright the exercise raises the following the next practice the next
work situation developed a program an effect cylinder using
using logic applications in the case here I am going to focus on
logical applications that appear in pneumatics modules and module
hydraulics so let's talk about logical applications or functions
logical and the logical function and because they are the
most used now we will understand also that we here are going to or
we study logical applications applying them from the force diagram
either from the control scheme or either in the hydraulic scheme or in the
electrical control scheme of that diagram in the case of pneumatics occurs
the same or not, if you understand me the difference possibly in pneumatics
they will also see it coming and at designed logical valves but also
in the electrical part I can do the game
the function is logical to igor from the electrical diagram in this case we
We will focus on what we will do from the electrical diagram the two functions
logical then says here the exercise create a one cylinder program
double acting using apps logical number one logical application org
to drive stem number two logical application and to stop the
stem return the operation of applications both heard and before
I invite you to see it in the explanations that we do or that already
we did in basic pneumatics because I'm also not going to do it here because
there is also internet many people who explain how it is that
they work and all this of the parameters or the truth table of in this case of
this function is logical then we are going to see it the following situation we are getting
asking us to act a cylinder of double effect with these two with these two
logical functions such that well we are going to occupy in our
own the outputs the physical outputs in this
case will represent me those read today from the solenoid valve that we are going to
be using to to activate the cylinder an effect in this case the
left side is one and one me will represent an output and the one on the side
right will be one of two just that let's take into account for the moment of
trigger when creating the program to operate this this actuator
double effect the program tells us good we are going to press the function or
for him to come out and later for that he enters we are going to press the function
and then in the software we are going to explain the programming we will
we will do as follows we will set aside this then to
start let's start with buttons we will make a contact
normally open we will assign the memory 1 and this is going to be ours
push button s 1 s 1 we will enter again we will
put here s 1
and we will also take a second push button that will represent that 2
let's see one thing 71 here we are going to assign it 2 and this is going to be known
like that 2 these two buttons well let's start I don't know why not
I had the comment here I think I accidentally deleted these two
push buttons are the ones that are going to me represent the logical function now
because i'm going to use the org function for the plunger to come out and the function
and for it to return well as in both functions I'm going to
use two buttons then here we have this button here these two
buttons who are we going to energize a coil we will make it so
indirect this coil will assign to the mark as well
mark 1 because we don't have any assigned
we are going to connect it like this there we have the first this brand
now we will use an assigned auxiliary to that brand to send to activate the cel
in today of the solenoid valve in this case is the selene today that is at
left side because we need that the solenoid valve moves changes from
position and the plunger comes out then you're going to be the selene today of 1 and 1
then we go to a for him to return well we are going to need the other two
buttons as we already have assigned the inputs 1 and 2 this is going to be the and 3
a second button that will be the input and 4
this one here to represent him is like if we are taking in order we already have
s1 s2 and s3 is going to be this one here and s 4 will be y 4 which represents
button of the condition
we are going to explain some of this now here we will energize a brand now
we have mark one we will assign it to mark 2 for now later
because the method that I'm using is the indirect method to now assign
an auxiliary open contact to that memory and in this way we are going to now
activate what the cel will represent in today from the side solenoid valve
right which is the q2 then this is going to be one of two
let's leave it like this and here ends my program now I
I was saying a moment ago and I was inviting you
to see the explanation of how it is that works
as he is the working principle of the logical functions both an and
because it is important to know what a simultaneity valve what is a
valve by how inlet works you go out and all those things that I'm not going to
stop at that part but yeah I'm going to explain the electrical part the part
electrical application function for us we do it is similar this
condition is like we are giving a connection of two in this case
are two normally open push buttons and these are going to be connected in parallel
in the case of the function these push buttons are going to be connected in
Serie so here we have s1
s2 here is a problem this is the s1 I don't know why I really don't know what
moment I put it there sometimes you have to be careful with that input one is
sure entered that 2 the two buttons they do the function for the official
we have studied who is conditional can you get me or can you
pass current if I press that one or if I press that 2 any ice cream that's why
here I say s1 and s2 to energize the mark 1 I can press that 1 or press
that 2 the truth table is also important to handle it I'm going to
explain this far right now when the energy reaches the mark 1
activate your assistant and this is how it will actuate on output 1 and 1 and the
plunger is going to come out now so that the return from your starting position use
we will use this other action group true this
which is here in such a way that we go here is the sum here is
multiplying the signals so in the case of this I could do
that one or it could be that two to memory one because in this case enough
with just having a positive pulse or one of these buttons is activated
so that mark 1 is energized in the case when you go back and you're
here we are using the function this in this case the function or I'm going to put
a text since for us to understand here and be a little clearer it seems more
interesting that this is the function
I think I can stop it now way here is the function here I don't know
where to put it and here we are going to put it in another color
It could be green and we are going to give it a size 36 to make it look more here is
the org function we are going to copy and paste because
here is going to be the function and then let's go in and this is the function
I was thinking of putting that label so that see here is where we are
using the org function and here we are going to be using the function a then
in the function there is necessarily for that there is activation of brand one
both input must be activated and three as the input and four in
programming or if we understand it the buttons must be pressed
normally open which are that 3 and that 4 when these two are pressed at the same time
energizes mark 2 mark 2 action a your auxiliary contact and that's how
current reaches output q 2 and will activate 1 and 2 and then the plunger will
return to its starting position
let's see in the simulation sorry what What I have done right now is change well
I have applied this by mistake right now to convert same diagram I have from
kot diagram contacts around here what we have to do later
tutorials on this also then in the simulation
I find it difficult in the simulation do all this programming but let's
to see to start these are one way buttons we are all going to go to parameters
it escaped me to make that conversion to each and every one when we came
doing but that doesn't matter because what you can do at the beginning and right now I
I have observed the error so I I'm setting up then when I
pulse in the case let's let's come here we will expand here in the case of
output q1 which is one of one just that we press either one or
let y two represent s1 and s2 for that output is activated then if I
I come momentum as we can observe and one mark 1 has been energized and
turned on that one stopped pressing it turns off the same thing can happen when
pulse and 2 look there it is also turn on both mark 1
like output q1 opposite case opposite is for when we return that
there we need to activate the treble output we need to activate both at the same time
and three like and 4 if I press and 3 what is that 3 is not going to
work if I come to press and 4 neither it will work how can I do to
press both at the same time here in our software well well let's do let's go
we are going to change this technique to one of them to switch so that
when we have it activated now we come to activate the other mode
push button and as we can see how we can observe we are doing this
technique only for explanation the q2 has turned on mark 2 and for
therefore the q2 which is the one that represents 1 and 2 which is the right side of the sel in today
of the solenoid valve and the cylinder piston will go well
I invite you to stay watching this tutorial but in the montage part
when we upload this to the logo to let them see how it really works and
that you are checking that in actually all these programs that
we're doing they're working fine This class video is already here
thank you very much to all who They have been seeing many thanks to
all those who are sharing this content with your friends on your
