hello everyone welcome to automation
0:15
Community today in this video we are
0:18
going to discuss an example which will
0:21
be about pump cycle so let's look at the
0:24
example first pump cycling turn on a
0:29
pump for 10 seconds second then off for
0:31
20 seconds and repeats this cycle that
0:35
means firstly the pump will turn on for
0:38
10 seconds then it will remain off for
0:41
20 seconds then again 10 seconds on 20
0:45
seconds off and it will repeat this
0:48
process again and again that is 10
0:50
seconds on 20 seconds off 10 seconds on
0:53
20 seconds off and so on so for this
0:57
example we will use normally open
1:00
contacts and normally Clos contacts we
1:03
will be also using a memory bit and some
1:06
timers like pulse timer and on delay
1:08
timer so let's move to TI portal where
1:12
we will draw a ladder diagram for this
1:15
example so this is the interface of di
1:18
portal let's go to PLC tags then default
1:22
tag table so here we need to add our
1:25
inputs and outputs so we have one input
1:28
that is start button
1:30
I will write
1:32
start
1:34
but and then we have one output that is
1:41
pump so we have only one input and one
1:45
one output and then we will go to
1:47
program blocks and Main
1:50
ob1 so here we will be drawing ladder
1:53
diagram so I will zoom into it
2:11
so firstly I will insert a normally open
2:13
contact that will be for
2:17
switch and then I will insert a Quil
2:20
that will be for
2:22
pump so I will select Palm from the
2:26
list and then this Palm should be on for
2:30
10 seconds for that I will insert a
2:32
timer that will be pulse timer so I will
2:35
go to timer operation then TP I will
2:38
double click here and then click on okay
2:40
so this
2:43
TP so this TP for this TP I will set the
2:48
preset value as 10 second so when start
2:53
button is
2:54
pressed when start button is turned on
2:58
then pump will turn on for 10 seconds
3:01
and then it will turn off
3:04
and after that I will open the branch
3:08
and I will insert a
3:09
coil this coil will be used for a memory
3:13
bit so I will assign address to it as
3:16
m.0 and we will use this m
3:19
0.0 to make the pump once again on after
3:23
20 seconds so we will use this m 0.0
3:26
here as normally close contact I will
3:30
assign address to it as M
3:33
0.0 and this m 0.0 should turn on after
3:38
20 seconds so for that I will insert a
3:41
timer t on that is an on delay timer and
3:45
the pump should turn on after every 20
3:48
seconds so the pulse timer will be 20
3:51
second but this will start when pump is
3:55
off so here we will use a normally close
3:58
contact and it will be as a pump so when
4:02
start
4:04
button is turned on as you can see here
4:07
this pump will turn on for 10 second and
4:10
after 10 second when pump will turn off
4:14
then this normally close contact will be
4:17
in Fall State and in Fall State the
4:19
current will flow through it and then
4:21
this timer will start so this timer will
4:24
start after 20 seconds so it will wait
4:26
for 20 second then M 0.0 gets through
4:30
and here when it gets through it will
4:32
not allow current to flow through it as
4:35
a result as a result the current will
4:37
not flow through it as a result this m
4:40
0.0 gets off it gets false and when M
4:44
0.0 gets off this m 0.0 as normally
4:48
closed contact in F state it will allow
4:51
current to flow through it as a result
4:54
this TP will once
4:57
again once again
5:00
uh note the time so this TP will allow
5:03
current to flow through it and as a
5:06
result it will turn on the pump and the
5:09
current will flow through this for 10
5:11
seconds only as a result this pump will
5:13
remain on for 10 seconds and this
5:16
process repeats again and again so we
5:19
will go to this option that uh starts a
5:22
simulation and then I will click on okay
5:25
and then we will wait for some time
5:37
after that I will click on
5:40
load and after that I will click on
5:43
finish so then we will start the CPU
5:46
here by clicking on okay and then we
5:49
will start monitoring after that we need
5:52
to switch to the project View and there
5:54
we need to create a new project so
5:57
firstly we will create a new project
5:59
here control n and then click on this
6:02
create and let's wait for some time
6:33
after that I will go to simulation table
6:35
and simulation table one and then right
6:38
click here and load project TXS so here
6:41
there is a start button
6:43
here and I will turn it on when I turn
6:46
it on this timer starts and this pump
6:49
will turn on and it will remain on for
6:52
10
6:56
seconds and after that it will turn off
6:59
and as a result this ton will start and
7:02
it
7:03
will
7:05
start and stop after 20
7:08
second and after 20 second this m 0.0
7:12
gets two this gets two this gets off and
7:15
once again the pump will turn on and
7:17
again the pump is turned on and it will
7:19
remain on for 10 second after that it
7:21
will wait again for 20 second and then
7:24
again pump will turn on after 10 seconds
7:26
it gets off and after that after 20
7:29
seconds this m 0.1 gets through this
7:31
gets through this gets off and this gets
7:34
off and as a result the pump will turn
7:37
again on so 12 13
7:45
14 and after that this pump goes again
7:48
on it was all about this example thank
7:51
you for watching
