Hi, I'm Teacher REYNER, I'm here again with one more exercise in Logo Soft
Comfort alright let's start what we know as pneumatics
sequential we are going to elaborate exercise schedules
pneumatic cylinder actions I hope you stay, I hope it helps
you are video classes alright the exercise raises the following
stock situation of a cylinder of double effect then says here elaborate
programming one of the following cylinder 1 to saleh working sequence
2 a leaves after one a returns two a returns when pressing is sure to run
open loop that single cycle and what We will do first in direct mode and mode
indirect truth the truth that no we know when it will serve us
these explanations either in mode direct and indirect mode since it is
pretty quick and easy then for here in this case in programming no
can we be explaining what is the phase space diagram and giving it
follow the order of the signals signs are those that guide the order
of cylinder actions and remember that these signs are ready
on the actuators both at the input as at the end of the tour of the
plungers all of that the space diagram phase we explain it well detailed in
in the basic pneumatics and something in electro pneumatic and electro
hydraulic ok then we'll move on to do this sequence
working the actions of this cylinder and well let's start from this
way then as we can see in a simple sequence therefore
let's do the first in direct mode and later we will do so
indirect as it is very direct because we are going to use the first entry so that
will be our start button ignition button and therefore you
we will assign input 1 then this going to be our start button
true and 1 input 1 will be our push button let's do this a
side because we are going to work up here so that we don't get too big
and we are going to expand to make it look as much clear possible for you guys out there
are understanding then here we we are going to energize our output q1
excuse me you hadn't supported me still good I had not come here but
let's let's talk about what we're going the elements that we are going to use in
pneumatic then from the pneumatic part on the power diagram so that the
control the control we do it in the logo the logo programming the
logos and strength is the part pneumatics then we will use 212
double acting pneumatic actuators the cylinder 1 and cylinder 2 we will use
for each of them two valves 5 two-way pathways that are bi stable
therefore as this is not cycle continuous truth is a single loop cycle
open because he goes in and out and there his house ends because I mean that
one leaves two then one enters and enter two and there die or end the
extraction the cylinders then it's a single cycle
therefore we will use only three limit switches two that are going to be
arranged in cylinder 1 and 1 which is going to be installed in cylinder 2 these
They will be entries here in the case of electro valves and stable let's
have two the in today of in each of they which will represent us
four read or ten in total so both will be four exits in such a way
that in programming we achieve the next the next action as it says
here we press that one comes out one comes out two one enters and two quickly enter here
we are going to do it again one comes out two enters one and then the
creditor two then these we're going to use all these components in this
case of the strength part not what we we are interested in the actions that
we will be representing the inputs indicated in the end signs
career and in the case of those read today since they are going to be represented
by the exits in the programming that are the q1 q2 cv34
we are going to pass it to the logo and here in the logo in the logo we are going to do the
programming so here we are going to use the output directly
1 we are going to assign 1 and this would be the serene n 11 then it would be 1 and 1
we are going to leave it like that and we connect it here now when it comes out it will press
or is it going to be an end of career contact already this end of career as it is a
physical input we will assign the input 2 we are going to put it here so that it does not
confuse then I will put it here in comment which is the end of career in
this case is the end of career 1 v 1 because when cylinder 1 comes out the
end of career he plays is when he is extended outside therefore this
is one of one now when he's already come out a touch is the end of career
we send the next action that would be q 2 then we came here the q2 me
represents that action and let's go let's enter its parameters and we will
put this is when the selene today of the electro valves 273
so that actuator 2 comes out then we come here and leave it here
now this working group is going to repeat because practically the
next action is the plunger coming back the first gradient plunger in this case
we will use the limit switch this is an entry we will assign the
input 3 because we already have input 1 and the 2 assigned and this is going to be the
end of career when in it the actuator 2 has gone out on its way
total then it would be the end of career 2 b 1
we don't assign here for us to go putting here and now we are going to assign here
practically the other way out the q3
here it would be q3 and this will represent the select today from what
cylinder 1 will return bone 2 this would be 12 for us to leave it here
and we connect it here now we come here for the last move we are going to
use the next limit switch that would be assigned to input 4
and here at entry 4 this end of career is when I'm back
actuator 1 therefore is going to be the limit switch 10 we are going to put
here in parameterization 1 b 0 and well let's assign the last output everything is going
to be in direct mode the output here of 4 going to represent
2 1 and 4 which is for the return of the actuator 2 here we already have it
virtually all programming pitifully direct way in the
simulation I will not be able to achieve no I will be able to do it because here
we press there is no retention but as we can see output 1 has been analyzed
when output 1 goes out the limit switch so that the other one comes out
actor when actuator 2 comes out and plays at the end of career when this is
extended which is 2 b 1 and 2 b 1 activates the next move that would be the end
of career 1 b 1 b 0 and to return actuator 2 don't see if I have
extended anyway because in the mounting part we are going to do a
a little more slowly and I assure you that they will now understand this so
direct for when we do so indirect is to use the coils come on
to try to do it a little bit fast then we come here we are going to download this
we come here and we're going to remove this the coil we're going to here we're going to act
We are going to assign a coil to this mark 1
now we use an open contact assigned to that mark would be the memory of
coil 1 so then indirectly we energize the selene
today of in this case would be the cel in today from the first solenoid valve now
for us to make this other move not we have to do something similar
but we are going to download this that is here we remove this one here
because only what we are going to do is energize one more coil now this
brand we will assign to brand 2 so that the software is not contradicted and
this contact to an assistant abnormally open it will belong to memory 2 and
memory 2 is who is going to activate that movement now we come here to
activate the next move would be and we just need this one and we're going to
leave it here that we eliminate here we will use another coil that would be
assigned to brand or memory 3 because we already have 1 and 2
assigned then we will respect that situation so they don't exist
contradictions in the software we use an auxiliary normally
open assigned to that memory so that let's activate the celluloid of the q3 which is 1
lledó now we only need to activate the last move which is that of q4
for this we will need a memory which we will assign
memory 12 stars are assigned because we will assign the one that is
continuation which is memory 4 in parameters we do that correctly
so that there are no contradictions in the software we use a contact
normally open auxiliary to that memory and in this way because here already
we will be and energizing the last output which is that 4 many specialists will say
that maybe this is not necessary but I I remember that in our classroom
it is important to teach young people that all young people learn what it is
boot or read directly today and that to activate it indirectly
ok here we are going to leave this programming in this case because we are going to
we will treat as we had already explained do the montage and record the
assembly for later you guys what see on our channel on our
platform well as up here we finish thank you all
those who are sharing our content with your friends on your networks
social we hope it will be of great help always our content that we are
getting on the platform it is the process to reign as always
