Hello everyone, how are you? I'm teacher REYNER. Today we are in
our youtube platform to follow studying simulation software
soft comfort brand logo serve for in this case we will be
working the a micro plc which are the of the siemens brand logos
So here we have 12 services we will remove this we have
the exercise of the previous day where we understood in three lamps
pilot but now what are we going to do of those same three lamps but with
self hold then we come here let's create a new file and what
we are going to drive so directly we create it here then
East and we already have it created here we are going to leave
to format we will change the grid to make it easier for us
mobility of the elements that we we have working then here we have
this we can select all this here and we can give you a copy and
we take to the scheme that we are going to be working right now we hit
so here we have the scheme of work and here we have the texts in
case of the text because we are going to to change it because this is going to be the
exercise number 2 then we are going to put exercise 2 let's put that
let's light the three lamps pilot but now we are going to
say this when pressing be the lamps are lowered and then we're going to
power when pressing we will need here stoke let's go shot
the lamps go out what does that mean as long as we are going to light and
turn off here we are going to need a feedback therefore we will
leave it this way here we have already our scheme the same as the
previous exercise well true here only it should be said so rather than
you can connect the lamps all we are going to put here we have
our being and now what we are going to do is this put a stop then
we come here we don't have our element tree and
we will make a contact normally closed we take it out here
by default it appears this way we are going to determine that
this is the contact number we already have good one we can do the following
we will also delete these contacts for us to start those from scratch and that
stay in an order an example this is going to be the contact
normally closed is going to be and one we leave it in none and here in
comment we are going to put that this is our stock so we will leave it
here in simulation we will leave it as push buttons we are both going to stop that
way now we come to a contact normally open and this is going to be 2
how is this going to be our second input and well nothing let's put the
comment here that this is going to be our ignition that is going to be the
start of our system this is going to be being in simulation we will leave
as a normally open button here We have both, we are going to download a
little so that it can be appreciated So let's see we've already studied here
let's get in the coil that will represent us in
this case in plc this coil is going to be a memory is going to be a memory
so here it is here is a memory we are looking here this is going to be the brand or
memory 1 and we are not going to connect anything here
then we come here we are going to look for a normally open contact and what are we
to connect that contact in parallel parallel will belong to memory
for us to look for the memory or we can type here m or we can also
go one by one until you find them where let's find the letter my and there we will
find us the coil the brand bud here we have the mark of the coil
one of the two ways i can search you can search by scrolling one by one or
type here the letter m in the search engine that immediately looks for it and
find then here we already have our authorization
so if we connect here we are going to do the interconnections in the
previous video I explained how self keep here I must look where
it can be conected remember I must find the point
make it compatible and well here I already we have then now after the
retention we will adjust I will do this to a contact
normally open belonging to the mark 1 and then there is this mark and here
He is the one who is going to send me to light the lamps so they stay self
retained so let's connect this one
element then already signal the lamp q3 we will also connect it in
parallel and as we can see well it goes to work this situation here in the
theory part we have to study true what does a brand mean that
mean the coils that are frame the coils that compares timer and everything
this kind of situation then like we can observe here we are going to
press start on the coil mark 1 will going to energize retains its contact this
contact will serve for retention this contact will serve to send
in this case turn on the three lamps this is the stock so now we come
here we are going to simulate the icon of simulation and here we can see the two
push buttons the push button and one that is for the push button and two that is on and
here we will understand we will find the coils then the m1 is a brand
then our lamps actually are the physical outputs in this case are
12 so now we are going to do the test
the proof is to be is this that is here it is gone we press it remains a nailed and the
lamp comes on we have to press here on and one that is the stop
so that the lamps go out and that way is how it is going to be
doing this test if we we come here to the buttons we are going to
zoom the buttons so that let's find this here when I press and
two because and two is the contact normally open ignition and one
is a contact I usually leave it normally good here says number 90
wind but well then here when we press the lamps are the
lamp q1 q2 and q3 which are the ones that represent the lamps are the ones that me
are going to represent or the ones that this is going to be lit then here in being
here turned off here in being and here I turn off and one
doing and two then this one turned them off here if someone sees me get to
ask why and one would appear normally open when
normally closed is because of the situation del let's say so about the connection or
reverse logic spoken in plc that we will explain later
in detail what logic means inverse of a contact when it appears from
this way then if we expand now zoom here we can find already
zoom in true if I do the simulation on the buttons that of
simulation down here the same happens in the top then doing this
simulation here is already more than clear truly connecting a
feedback is to explain what is the feedback or retention
electric and the we explained in classes earlier however I'm just
explaining the connection here or spend more that the whole electric single diagram
that we have been using the diagram cot or ladder diagram then of
this way we are going to come working the simulation
in logos or comfort to be able to do it diagram or programming in the dra
to be able to later do mounts by transferring the program to a
logo and do real montages well without nothing more to say as I say goodbye to
all of you wishing as always best
