hello everyone welcome to automation
0:14
Community today in this video we are
0:17
going to discuss an example which will
0:19
be about Machine Tool and coolant so
0:22
let's look at the example first machine
0:25
tool coolant control the coolant should
0:28
activate when the Machine Tool starts
0:30
and continue for 5 seconds after the
0:33
tool stops the Machine Tool will operate
0:35
for 10 seconds with a break of 5 Seconds
0:39
so for this example we will use some
0:41
normally open contacts and normally
0:43
close contacts we will be also using
0:46
some memory bits and timers like TP and
0:49
T on so let's move to TI portal where we
0:53
will draw a ladder diagram for this
0:55
example this is the interface of di
0:58
portal firstly we we will go to PLC tags
1:01
and then default tag table so here we
1:04
will add our inputs and
1:07
outputs the first input is start button
1:11
and then we have some outputs the first
1:14
one is
1:17
coolant so this is an output so its
1:20
address will be Q
1:23
0.0 and then we
1:28
have Max
1:31
mhen
1:33
tool and its address will be K 0.1 so we
1:37
have two outputs and one input after
1:40
that I will double click on program
1:43
blocks and then main
1:47
ob1 so here we will draw the lateral
1:50
diagram so I will zoom into it like this
1:53
so firstly I will insert a normally open
1:56
contact and a coils this normally open
1:58
contact will be used for the start
2:00
button and the coil will be the Machine
2:05
Tool and this machine tool for 10
2:08
seconds so there will be a timer
2:12
operation used and that will be TP and
2:15
the preset value for TP will be 10
2:19
seconds and after
2:28
that the cooler
2:31
will be used I will open the branch and
2:34
then add a coil so this coil will be
2:36
used for the coolant and this coolant
2:40
will operate for 15 seconds so for that
2:43
we will use a TP here and the preset
2:47
value for TP will be 15
2:53
seconds and after
2:57
that I will use Network 2 and use a
3:00
normally open contact for the start
3:03
button and then we will insert a coil
3:06
that will be a memory bit M
3:09
0.0 and this m
3:15
0.0 the masching tool should operate for
3:19
40
3:21
seconds and then the
3:24
coolant will operate for 45 seconds
3:30
because the coolant should operate even
3:32
if the co machine tool is off so it will
3:34
be on uh for 5 seconds mode and then
3:40
here this m 0.0 will be used here so
3:44
this m 0.0 gets on after every 10
3:47
seconds so this will be uh t on will be
3:50
used here and the preset value will be
3:52
10
3:54
seconds and then this m 0.0 will be used
3:58
here as normal close contact so I will
4:02
write the address as M
4:04
0.0 and then this m 0.0 will be
4:09
used again so we'll use Network 3 where
4:13
we will use a normally open contact and
4:16
this normally open contact will be a
4:18
start button and then here will be a
4:22
coil and this Quil will be one more
4:25
memory bit let's say m
4:27
0.1 and this m 0.1 one gets activated
4:31
after 5
4:33
seconds so there will be t on and the
4:35
preset value will be 5 5
4:38
seconds and then it will get on when the
4:41
coolant is off so here we will use a
4:43
normally closed contact and this will be
4:47
coolant and also we will use a normally
4:50
closed contact and this will be M
4:53
0.1 and this m 0.1 will be used here for
4:58
coolant here as normally closed contact
5:02
and this is M
5:04
0.1 with that this
5:07
m.0 should get on when the Machine Tool
5:11
is
5:15
off so this is Machine Tool so what
5:19
happens is that when start button is
5:22
pressed this machine tool gets on for 40
5:25
seconds and then after 40 seconds after
5:30
40 seconds when Q 0.0 gets off the
5:34
coolant doesn't get off when start
5:36
button is turned on both gets on the
5:38
Machine Tool gets on for 40 seconds and
5:41
coolant for 45 seconds with that when
5:44
Machine Tool gets off when Machine Tool
5:47
gets off the current flows through this
5:49
and this m 0.0 is also true in the is
5:54
also falls in the beginning so the
5:56
current will flow through this and this
5:58
m 0.0 get gets through after 10 seconds
6:01
and after 10 seconds when this m 0.0
6:04
gets through this m 0.0 gets through the
6:08
current will not flow through this and
6:09
as a result this
6:11
m.0 gets
6:13
off and
6:20
then so when this m 0.0 gets through
6:24
here we'll use a normally closed contact
6:26
for M
6:27
0.0 so first ly it gets true it gets
6:31
true the current doesn't flow through
6:33
this and as a result this gets true and
6:35
this gets false and as a result this
6:38
timer again starts after 10 seconds so
6:41
again Machine Tool gets on for 40
6:44
seconds then again gets off and then M
6:47
0.0 gets through then it gets through
6:50
then it gets off and it gets off and
6:52
with that this gets on and off then
6:54
again making the machine tool to operate
6:57
for 40 seconds and with that the coolant
7:01
the Machine Tool operates for 40 seconds
7:03
but coolant operates 50 seconds 5
7:06
Seconds more that means 45 seconds and
7:09
then when this m0 this start button is
7:12
on and the coolant gets off after
7:14
operating for 45 second this m 0.1 gets
7:17
through after 5 Second and when it gets
7:20
through it gets through and it gets off
7:23
and when it gets off then here this TP
7:27
once again starts and the coolant gets
7:29
on again so I will start the simulation
7:33
here the process is automat automatic
7:36
the whole process is automatic and it
7:38
will repeat this process again and again
7:41
so the Machine Tool will operate for 40
7:44
40 seconds and then a break of 10
7:46
seconds will be there 40 seconds on
7:48
click on load 5 Seconds uh 10 seconds
7:51
off 40 seconds on 10 seconds off and
7:54
then for the coolant it will be on for
7:57
45 seconds then off for 5 seconds 45
8:00
seconds on for uh 10 second 5 Seconds
8:03
off I will start the CPU
8:06
here and then start simulation start
8:09
monitoring and after that I will switch
8:11
to project
8:16
view let's create a new project
8:53
after that I will go to simulation
8:55
tables and then simulation table one
8:58
right click here and and load project
9:00
TXS so here when I turn on the start
9:03
button you can see here when I turn on
9:06
the start button Machine Tool started
9:09
working and it will work for 40 seconds
9:13
and with that the coolant will also
9:15
operate so the Machine Tool will uh turn
9:19
off after 40 seconds but the coolant
9:22
will be on for 5 seconds more
9:43
so after 40 seconds Machine Tool gets
9:46
off but the coolant gets on so M 0.0
9:49
gets to gets off and then with that
9:52
machine tool again starts working but
9:54
the coolant St for 5 seconds after that
9:58
machine tool and coolant also got
10:01
on and the Machine Tool will operate for
10:04
40 seconds and then will stop the
10:06
coolant will continue for 5 seconds more
10:09
and both will stop for 5 seconds and
10:11
then again Machine Tool and coolant will
10:14
work it was all about this example thank
10:17
you for watching
