hello everyone myself badas in this
0:11
video I will discuss about pulse relay
0:16
open your PLC software and on the left
0:19
side scroll down and select pulse relay
0:25
here and add the comment first this is
0:30
pulse relay and click
0:40
okay if you see there are three inputs
0:44
trigger set reset and one output these
0:48
are digital signals so take the digital
1:06
take I3 and I4 for set and
1:20
reset i1 is my input trigger so I will
1:32
I3 is my set input I'll write
1:38
okay connect I4 is my reset input I will
1:55
output now arrange properly
2:23
Hardware now download the
2:28
program if you don't don't have the PLC
2:31
Hardware with you no problem just do the
2:35
simulation and verify the logic try to
2:39
avoid only watching the videos do
2:48
programming meanwhile share our videos
2:52
videos and subscribe to the channel so
2:55
that you will receive more
2:58
updates first we will learn about pulse
3:02
relay this pulse relay have two
3:06
functions the first one is the input
3:11
trigger this trigger will toggle the
3:15
output State whenever one input pulse is
3:19
received from the trigger then the
3:23
output state will change if the output
3:27
is in off State then it will be on
3:31
if the output is in on state
3:34
then it will be off whenever the pulse
3:41
the trigger input every time the output
3:45
state will change first we will verify
3:48
that so whenever we give one input at i1
3:53
input i1 is pressed and
3:57
released then output will
4:00
change it State previously it is in off
4:03
State now it is in on state okay again I
4:10
pulse output is off again I will give
4:15
pulse output is on you can see here
4:18
output one is on like that for each time
4:23
the input pulse is there then output
4:26
will change its state off to on on to
4:33
simple now we will learn the second
4:37
function this is nothing but rs
4:43
relay if my set input is
4:46
on one pulse is there then output is on
4:51
if my reset input is on then output is
4:55
off we have one additional property is
5:02
properties here you have the option to
5:06
give which input have the highest
5:09
priority set input or reset input by
5:13
default reset input is having the high
5:17
priority okay we can change that
5:20
function select the second
5:22
input and click okay the second input
5:25
means the set input is having high
5:28
priority and the reset that is what we
5:34
okay now I will activate input
5:37
I3 output is on now I will activate
5:42
I4 output is off now again I will turn
5:47
on input I4 and I will keep it like that
5:50
now I will turn on input I3 set input
5:55
what happens my output is on because set
5:59
is having the high priority in this case
6:03
the PLC will ignore the status of reset
6:06
it will only consider the status of set
6:08
input and we'll activate the output
6:11
accordingly for example now in this case
6:15
I will make reset is having high
6:17
priority that means output will be off
6:20
reset means zero set means one see I
6:24
will change the state again the first
6:26
one I selected this is reset input is is
6:29
having high priority and click okay
6:32
output is off reset is having priority
6:36
in this case PLC considers only reset
6:38
input it will ignore the set input
6:41
status so reset is zero output is zero
6:46
like that you can select which input is
6:49
having high priority which input you
6:50
want to have the high priority in normal
6:53
safety applications or normal
6:55
applications generally reset is having
6:58
high priority in some applications set
7:01
is also having some priority if you have
7:04
any industrial experience share with us
7:07
where you used set priority reset
7:12
applications you can find these type of
7:15
applications priority applications okay
7:18
set priority reset priority share with
7:20
us through the comment section thank you
7:23
I will meet you in the next video
