Hi, I'm Professor REYNER, thank you for watching and sharing our video classes with your friends.
this time we are going to do the assembly of a second class video
always with the SIEMENS S7-200 PLC well I hope this kind of help I hope you
stay until the end watching the video classes we are going to do the second montage
in the first we made a small introduction we talk some appendix
we did a tour we have already done another video creation where we explain how it is
the brand coach so come on to be using however always
it is worth reminding you that for this class they must handle what the inputs are
are the outputs as are the variables countless terms that are
important to be able to identify and not stay active let's do a second
assembly exercise dictates the following working condition we press that 0 which
It is march making lamps and will stay on until
Let's press for this it is in this in the first we only had a push button
march now in this exercise we are going to have a start button and a
payment button but I hope it's from help for
to those who are studying automation ok then that ya
we have the file we already have the plc with energy then let's go oh well let's
load the program, we go to the icon where it tells us that we can
load the file to the cpu of the plc we give it to load here in the option where
it says load on cpu in the video above we explain quite slowly all this
situation tells us that if we want switch cpu unit from mode to mode
stop if the plc is in run mode is running or running programs or let's go
to be able to load it for at least this way we should see the selection
also that it is here in test mode no can be there in mode this is mode
root we give it ok and let's see what it's loading there and the little file
simulating that the small file now when it has already
loaded we can see there that it has set a mode this is true here too
the plc looks
I hope you can see the brand there orange now when we say
that if the cpu mode passes this go to run I'm going to give it ok here it goes
turn green I hope it is achieved see there
and there you could see that it has happened green color well now we have
practically in charge of the program let's make the connections
we will always use our panel buttons to enter the
signal input and this is where we will be using the lamps
then we are going to put the common here because we have addressed the
100 and now we are going to direct to the
first button the green button I did it 20.0 that is who is march
after the y 0.1 and 0.1 who is unemployed so we connect in this way very
common excuse me not seeing everything the favorite colors
now we are going to connect what are the exits and we make exits to the
common to the common we are going to connect it to the negative
from this source and now the positive is going to
white
we connect the positive of the source towards the lamps
and I think he's seeing us there let's go put here
the positive of the source towards lamps
I have connected this the fountain
the lamp and the negative to the common plc
then the negative of the source al common of the outputs and the positive to the
camera now let's bridge in this case the lamp is the first
lamp will go to the zero point cruise
the second lamp at q 0.1
and here we just need to finish put the positive to the second lamp
so that everything is finished is the execution of the program then
now if I come to press gear we must already know that it must have energy
the psn the day of the fountain when let's press the lamps
they will be held on we press for the lamps should be turned off
now we are going to do a test until here without camera tripod
Now, what can we do? well let's try to see a
example let's see the status of the program that we have not done not
we have done so far but ok let's start here here we now
how can we see here we are going to press when I press the y 0.0
activated your 0 0 and 0 1 when it stopped press a 0 0 0 0 0 0 sorry and 0 0 will
turns off but remains on 0.08 0.1 in I change when I come I push the
input and 0.1 should be turned off using a zero point and with 0.1 then let's see
press we see below that it has been input activated and 0.00 point 0 and
up now that deactivated here because I have left pressing these are activated
from here when I pulse when I now I come to press a 0.1 this here is
must turn off the inputs the outputs they will see to pay then
press and see that it will turn off and when turns off
this is the same thing that happens here at this distance we press we see the plc
of the psd lights on I stop press the input turns off now the other
input is for shutdown and shutdown the lamps have already seen the other one
situation I was telling you is that we are going to see the status of the program we come
here to the icon to the icon we have in the pc to program status when
we activate that icon let's observe that here you put a line
blue and you can see the icons that are with activation in this case contact
closed when we click here March
how to look at it when we press on
and everything is activated here in the plc as we have been studying it is also going to
reflect here in the program
now look here in the software I stop press only the case of the
gear switch which is and 0.0 the rest remains on press
we press more than stop the real lamps so turn this off
from here but the system is also turned off and
they turn off the plc lights the light goes out in the perez then
let's try to see the other perspective when we press gear
let's try to see here we're going to put it here when we click
March
the lights come on and let's see how is the program
now we see that gear is and 0.0 when I release the button that is when I
release this button here it should be also disconnect the one from here
Program
and everything else that makes sense like we can see there is going is 0.0 if
We come to the LEDs that indicate here
in the plc the y 0.0 which is this here is the only one that is off must have been
a zero point is off now we come here to turn off the
program well then I will have to press for unemployment is 0.1
but it's 0.1 so when i press I stop I stop is the color button
blue you will have to pay everything in verón and that is what happens it turns on and off it
turns on and off right now let's do a second
exercise in this same video class then I'm going to come to file
filed and I will open in this case I will look for the other exercise
well this exercise consists of a small change we have made in the
programming but not physically we have changed absolutely nothing
then we look for the exercise that I have saved here
then when i find it we are going to see exercise number 4 because
the number 3 we were doing I don't know how we can see here
I have not made any changes to the part of mounting only in the programming part
what does that mean or how is it going to work is now pressing gear
feels memory feels se turn on a timer a timer 5
seconds later or 12 seconds later 10 seconds later they should turn on
the two lamps then now we can do is load the program
we come we load the program I have not done changes in the programs in the part
physics in the part of the connections that I have made the change is in the part
of programming because now I'm going to press gear in a while after
they are going to light the lamps well now we have loaded the program
now we come to see the execution then we press
I'm leaving so they can see we wait for that time to be
programmed we must wait the time that has
programmed and how can we observe things It seems like a long time there, I know
they have lit the lamps now we pressed stop you saw then now
we come here to see the status of the program in programming is where I have
made change installing ls
this time deserves this timer and well now how can we see the status
of the program there it is then when pressing march I come pulse march here like
we can see there the timer is doing his job after time
when time passes it will come to light up here you only see a lamp
here you only see a day lamp they lit the lamp as we can see
here the other lamp has been lit we are also going to turn it off
we prepare now I will try to leave it at this distance I will try to record
this distance for you to see we press gear
remove the pulse also saw that it they activated the lights here and now
we wait there for the prudent time you have set it to be 10 seconds
approximately we already see they are not less then we see there that the lamps
they have turned on we have not done any change in programming then now
here we come and turn off
still without making changes now we go to open
other another program you have already run that already
I have elaborated what is the number exercise number 5 all these are
programming classes are already in video tutorials will be in
our youtube channel how to programming to explain the use of
timer and all those situations then exercise number 5
now exercise 15 poses another small situation the situation will be
that we press march a while passed the lamp is lit
another time passes and they turn off automatically so in this
occasion I do not need to press stop so that they turn off
the plants will go out after a certain time that I need
turn them off before that time for that we have installed a strike then
we are going to load the program we come here where
to the icon to load the program we give the good
I mention again that all this situation and we are going to put this on
so that the program loads all this now must be done programming must already
be compiled and everything else we will put it now in room mode I tell it
yes and in advance I will have been for next time we will see something else
details little by little we will see the details then there is already a time
of the programmed I'm going to try to record from around here
we have here we press march we wait a while
and that it has been programmed so that after that time has elapsed
the lamps should light having the lamp is switched on after a
second time so that later the lamps go out all that time
It is programmed and the cycle ends there in the next video class we can
do it with an accountant then we come here as we can see press march
the lamps have been lit there and here in the programming we can see
let's see the second half here here so the lamps lit as we can
see then there it is showing that the lamps are off and here
we can monitor the state of each of the variables as
we can see here is turning on and turning that off I hadn't mentioned it
I really hadn't mentioned it then they will be turning on and off
turning on and off that way they go to be allow you practically the
lamps turning on and off turning on and off from then when
the time passes again lamps are lit here as we can
see and let's try to put down the camera here there the lamps are lit
now they turned off it happens again again for a while
the lamps so that the lamps are turn on
let's wait and good this way we will give you the completion is ready
class so that it does not exceed 20 minutes let's try to explain it slowly
step by step explaining each of the connections in my little learning that
I have then the years also that I have teach it because I think it explains it to me
slow enough so that you can understand
I repeat the programming of all this from this operating system use and management
It is in other videos classes that you have to see the truth and where we explain how
make the connections of the the exit
the coils the memories are carried by the timer how to use the timers
the timers that in this operating system well it varies a little well here we are going to give
how finished this video class
I hope this video is one of support for all of you this I ask for class
is serving you I thank all who have joined our platform
from youtube are sharing the content leave me a comment
we remind you that this platform is to learn together to get ahead
It is not we are going to tell you so what knows everything there are always things to learn
there are always things that we can keep improving with many thanks
have a good day
and
plus
