hello everyone welcome to automation
0:19
community in this session we are going
0:21
to see one more example in Omrron PLC so
0:25
without any further delay we'll enter
0:28
into the example so draw the program for
0:32
blinking of circuit I mean blinking of
0:35
light 1 second on and 1 second off so
0:38
this is a perfect example
0:41
for to understand the importance and the
0:44
working future of timers okay so
0:48
obviously to make the output on and off
0:52
continuously you need you are in need of
0:55
a timer so how we can tell that we have
0:58
to use a timer means 1 second on and 1
1:00
second off how we are going to calculate
1:03
that 1 second and that depends upon the
1:07
timer okay so that's what we are going
1:10
to do and uh let's move on to the
1:13
software and see how to do this blinking
1:22
circuit okay so initially I want to have
1:25
one control okay whenever you are
1:28
turning on that time only your circuit
1:30
have to start so for that you are in
1:32
need of one input no so let's make that
1:38
so I'm going to name that
1:47
start start input or start
1:58
switch okay and uh what else we want we
2:02
want one output correct that will be our
2:09
output all right so yes I have one input
2:13
and one output so whenever I'm turning
2:16
on this input this light have to be on
2:19
for 1 second and off for another second
2:21
and this cycle have to continue until I
2:29
right fine so now what is
2:33
the condition we have to write what is
2:35
the logic we have to write so what I'm
2:37
going to do whenever I'm turning on this
2:39
uh you know uh this input no I'm going
2:42
to turn on one timer also so I'm taking
2:46
one timer and this is our on delay timer
2:49
so pim and I'm naming the timer as zero
2:53
and I'm giving the time delay
2:55
as 1 second so 1 second means what I
3:04
okay so hash 10 means it's once again so
3:07
I'm giving Okay all right so it's
3:12
now so whenever you are turning on your
3:15
uh input no that time your timer will
3:18
also start counting just a
3:26
yeah now the timer is getting
3:30
start initially your output is on see
3:33
whenever you are turning on this output
3:35
will be on no so after 1 second I have
3:37
to turn off this that after 1 second how
3:43
calculation for that only we are using
3:45
this timer see this tim if you have seen
3:49
our previous sessions we have we have
3:51
the you know video for uh this timer Tim
3:54
Tim or delay timer okay so what it will
3:58
do whenever you are turning on after 1
4:00
second the timer output will get turned
4:03
correct so what I'm going to do by using
4:06
that output I'm going to turn off my
4:10
input okay so by using that out output
4:14
I'm going to turn off my
4:16
input so what I'm going to do is I'm
4:19
going to have one more uh you know
4:26
take and I'm giving the timer
4:29
address this is my timer now t 0 T 0 I'm
4:33
going to get help from one memory
4:41
bit so by using this memory bit I'm
4:46
my output so after 1 seconds this memory
4:50
input will be turning on no this memory
4:52
output using that I'm going to turn off
4:55
my light so to turn off that light we
4:58
have to what we have to do we have to
4:59
break the contact so that's Why I'm
5:01
going to use normally closed contact
5:06
10.0 all right so after 1 second my
5:10
output is going off correct so what we
5:15
again after 1 second of that again my
5:18
output have to be in on condition so for
5:22
that I'm going to get help from one more
5:25
timer Tim because we have to calculate
5:29
the one on and one off no so for one
5:32
timer it's one uh uh you know 1 second
5:35
for another timer is for another 1
5:38
second okay so I'm going to this uh name
5:41
this timer as one and uh for same thing
5:44
I'm going to give a time delay as you
5:47
know 10 I mean 1 second okay so by using
5:52
this timer I'm going to reset this
5:55
condition so what is the purpose of
5:57
resetting means it will restart the
6:00
process i'm going to give the timer
6:07
okay so why I have given here is it will
6:11
restart the timer again so once you
6:13
restart the timer what will happen this
6:15
fellow will go off if this fellow go off
6:18
the light will again turn on so 1 second
6:25
okay so look at this i'm going to do the
6:38
simulation okay so let's turn on my
6:43
input yeah can you see just watch this 1
6:48
second on 1 second off 1 second on 1
6:51
second off so this is what our
6:53
requirement is right so with this simple
6:56
example we can understand the working of
6:59
timer correct so two timers one to turn
7:06
off so with this we have taken the help
7:15
with the help of that we have turn on
7:19
this without that memory bit also we can
7:22
able to do we can directly put this uh
7:25
you know timer address over here this is
7:27
just a supporting bit
7:29
only see you can put this over here
7:33
instead of memory bit you can put the
7:34
timer address directly
7:38
okay so I hope you have understand this
7:41
blinking of circuit just try
7:45
this like these examples and videos
7:48
kindly like and subscribe our channel
7:49
for updates and videos so I'll meet you
7:53
in the another session with another
7:55
example until then thank you
