Hello young, how are you? Professor REYNER, today we are going to
continue with another class video where we will continue explaining some
software application exercises wolf shot conform 8.2 good and I hope
well this this these videos these classes I am helping all of our
followers on youtube today let's find an exercise of
timer application we will continue doing an exercise applying
timer later we will talk about exercises to apply this logo
acting on pneumatic cylinders and then we will go to engines well
so I hope it's helpful stay watching this this video class well the
exercise raises the following situation let's read it to see which
are the working conditions of the saga create the ignition program and
off two lamps with the following working conditions number
one by pressing start after three seconds lamps light number 2 6
Seconds later it's lit the lamps go out
automatically and there the cycle dies you I remember that your exercises are basic
they are simple they are simple they are for beginners so we can start
use the software I recommend when we are here we have
to see the tutorials where we explain that it is a plc of the types of
plc the characteristics of a logo all microcontroller thing because it's there
where we are going to learn what it is a timer memory how the
types of timer special memories outputs and inputs that are physical and
well I don't know everything to the whole theory so let's start doing this
exercise here we already already we saw what a hold was so
so much I will not stop explaining that then we will start and doing
our exercise first let's get our first post we're going to
use it as off then this is going to be ours
and 1 and it will represent our shutdown then we will make a contact
open which will represent y 2 and will be ours in this case our
switched on let's see and two and two let's see
about this situation and two and well for default this program has that
situation that always puts the name the previous contact then
we will go into this and we will repair this situation
only when we put it this way then this is our ignition and
here our shutdown now comes let's use a memory then this
memory is a coil since we've been here we are going to assign that this is the
memory 1 I remind you that you can search each one of the memories moving here
or by typing the initial of the green variable then we put m we go
to assign memory 1 to m1 and now we are going to make a contact
open we will assign it to memory to make our retention here
it is basic we are going to interconnect it here we need another situation than
we will see later then already we know that this one here is a retention
correct now we will use a memory contact m1 which
we will assign that contact to memory here we are going to measure two times we are going to
time for ignition and a time for shutdown i'm going to do it
in this way I remember that in programming is is a wide world and
there can be no number of answers different for the same for the same
work situation i'm going to use the timer with trying connection
so this is going to be timer 1 and we will place the 6 the three seconds
you're asking us for matrix come on to parameterize the three seconds now
after this timer we are going to search for an open contact associated with
this timer then let's look here we have timer 1 and logically that
Now we are going to send to light our element in this case what we
let's light are two lamps then the lamps me
will represent the output elements therefore we are going to look for
our exits which is that one and not our second exit would be q2
so here that the lamp 1
lamp number 1 well let's put it now as we are in the norm we are going to
put h 1
2 will represent me the lamp two do comment let's put this is h 2
and so we are going to leave it h1 h2 lamp a lamp 2 now we can here
observe how good we are going to light memory is going to retain hand turn on
the timer the timer counts three seconds send to close your contact and
light these two lamps that's what is going to happen right now
so if we come to simulate well here we have these and what
we have in switches mode we are going to put it in push button mode let's
let's change this parameter then now let's do the simulation and 2 me
stands for therefore we press we stop pressing and it holds
there is counting the timer finish count and light up now I need
count a second time for it to turn off then we will locate a
second timer down here a second timer and this timer
it will turn on another contact of this same workshop then I can take out
from our component library another other other contact or I can
give it copy and paste this same contact here then now this one
we will give six seconds because they are six seconds the ones that will last from
let it light then how can we observe here timer 1 turns on the
lamp since you turn on the lamp turn on the second timer which is the one
going to start counting him lamp on time
lamps will last 10 to 6 seconds lit then if we do the
simulation we do there bernat to the simulation we turn pass the 3
seconds come on and how can we observe there are counting the 6
seconds when he finishes counting those 6 seconds as we can see
there we now need to send a work this timer this timer is going to
send the system off then to send it to stop we need
and connect it in the line of work in where is everything that is the control of
command then it would be in this line so we come here looking for a
closed contact that will belong to you to timer 2 I remind you that here
we can search the element scrolling until we reach the
where are the timers or locating the initial variable and when you find it
we select it to indicate that this component belongs or is
associated with that coil then here we have now connected in this way
let's see here is the indicative the indication of the problem we lower it and
let's do a little simulation let's simulate here
so if we explain how works by pressing the input and 2 which is
the one representing the ignition is going to energize memory 1 memory one goes
to activate your contacts in this case the first contact is this one here is
the one withholding the signal this second contact is the boss
turn on the timer by turning on the timer starts its count of three
seconds when all three finish seconds in 100 of your contact which is
who is here and who is going to send to light the lamps
communicated two that represent me the lamps but this timer has
commanded to light the lamp and also has sent to light a second
timer who is who is going to represent the time they will be
the lamps on or six seconds later this one is going to send them to
pay then how this little one works program we will do the simulation
now we turn on the count starts finish counting light up the
lamps as we can see starts the another count and then they go off and there
the system ends then to start it again now let's do
simulation from for pain the buttons that are here then
we press and two that is on it turn on
memory a time after three seconds then the lamps are lit six
seconds later all the system and this is how this works
situation then we light three seconds later the
outputs that are lamps q1 and q2 six seconds later all the
system well he's asking us we remember that
these exercises are for beginners for us to start using the
software and logic programming that already for someone who has worked years in the
industry because this is too much of easy however we are
doing for the students that we are starting to learn about this
software well this exercise ends here I'll wait for you in the other video where
we are going to do another class with a small variant a small condition
plus we are going to add situations working conditions every
working condition will generate a new programming and that's what we try
make the young man begin to wake up the mind
and have the initiative to start look for variants or different
solutions to the same program well Thank you all very much for having
seen this class video everyone have a good day say goodbye to you
