so this video is going to introduce you
about the six other timer functions for
the ladder logic program in Zen your
smart realize a little bit more catch up
on this demo program input discrete
input number wise controlling the
command coil of timer one input number
two discrete input number two is
controlling the reset coil of the timer
number one t1 is the timer contact Q
eyes are discrete output contact on a
smart relay and also the discrete output
count habit can light up the LCD
backlight off on the smart relays so if
I close I one the timer contact should
actually it's correspondingly
so let's look at the function DISA
magical flashing select this function by
click on the radio buttons as you can
see here if we energized command coil of
the timer gt1 kentuckyone will pick up
immediately when we energize the
kinetochore Kiki one as last the
canonical you TTY is energized the
contact t1 of the timer will pick up and
then drop off automatically and
alternatively please be advised on and
off time for the contact t1 it's the
same that's why it because it's
symmetrical flasher and we can set that
on of time by changing the dados here in
the time window and select the timing
units so now that's set the flashing
time to be 1 seconds and the simulator
the power go to the simulation mode
around the simulation program now we can
see that the function of the timer has
been set to D it's a magical flasher
unit and Rojo down which means that we
need to energize to the command call you
all the time so this timer contact will
pick up and drop off alternatively and
it really energized optimal Toyo the
timer contact will go back to the shelf
state let's try it here so energize the
command coil by closing input I won and
as we can see output contact which is
controlled by the timer contact here it
is flashing alternatively there is a
timing get rid of 1 seconds so on for 1
second off more one second this is
called the symmetrical flasher that's it
okay so now let's look at a function PD
symmetrical flashing start/stop on pause
select this function by click on the
radio button here as we can see if we
energize the command call you off the
timer here the timer can't have the key
one will pick up immediately at the
rising edge and then chopped off and do
this kind of behavior alternatively
please be otherwise the timing period if
on the wrong time enough time are the
same only if we energize the reset code
of this timer the t1 will go back to the
shelf state they still set on the timing
period to be one seconds so let's see
how the simulation works out run a
simulation as you can see the timer
function has been set to function PD
symmetrical flasher press to start let's
see how it works here we energize the
Koyo
T t1 by closing the input 1 here and
then we can release it and as we can see
the input Y is not holding anymore we
just need to KB the rising edge and then
this time we will continue to flash if
we want it to stop we need to energize
the reset coil by closing in code number
two later close I to start i want once
the screen output q1 starts to flash the
close i two stops
that's it
okay now let's look at function key time
on addition select this timer function
by clicking on the radio button here and
as we can see here this function is kind
of complicated how it works is that if
we energize the command call for a
specific period this timer contact will
not become only if the accumulated
energized time for the command code
reaches our preset value the timer
contact will pick up and then only if we
energize the reset call you the timer
contact will drop off let's change the
accumulated time to 3 seconds and see
how it works around simulation program
and I can see that the function has been
sent a function T and the total time we
need to energize the tamerica oh it's 3
seconds how many times we energize it
and then the relay output q1 will pick
up so I'll try it here please look at
the current counter on this timer here
so energize the ones for their 0.7
seconds it's not picking up and he tries
it again 1.6 seconds still not pick up
and it drives it again 2.7 seconds it's
still not picking up and it tries it
again
the breach is 3 seconds and as you can
see the timer contact and T 1 is closed
constantly and then our really output
queue is picked up so only if we
energize the reset coil this timer
contact will chop off so it's not you
squid output on the smart really so if
we energize to command coil for 3
seconds from one time you pick up
immediately
after three seconds
one thing to mention is that oh if we
hold in the command call you hear the
resent coil will become some kind of
house mechanism as we can see that just
start from beginning as we can see hold
in the input for the command code for 30
seconds really output picks up timer
contact you stop and if we energize the
reset coil here the counter will
restarts for three seconds later do pick
up again
that's it
okay now let's look at the function AC
select this function by clicking on the
radio button here so we can see here the
time sickness in my grammar tells us so
if we energize the command a coil for a
specific period TA and then contact
after timer will pick up and then if we
de energize the Koivu command call UT
one after a certain time
some civic time the same as TB is timer
contact your jump-off
so let's look at how this thing works
they set of the off delay time to be two
seconds and our nearly time to these
three seconds so function AC is
basically our off delay timer let's see
how it works here run simulation as we
can see the function has been set to on
and off delay so we can adjust me I'll
call you after 3 seconds it picks up and
then you stay on as long as we hold in
the command coil the contact stay on so
you free the energize the coil after 2
seconds you keep your job half
that's it
okay now let's look at the function f1
functionally is described as flashing
unit control hold on any synchronously
actually this is a asynchronous or
asymmetrical flasher as you can see that
as long as we energized the the command
Co yo at the rising edge the timer
contact t1 will pick up for the specific
time in Sandy - and then drop off for
specific time we said in - and do this
kind of behavior alternatively so this
is a asymmetrical flasher and as well as
we energize the command call you a
contact high off the timer t1 will go
back to the shelf state so we set an on
time to be 2 seconds and set off time to
be 1 seconds save it go to the
simulation lon as you can see function
has been set to function l is
symmetrical flasher so on time for one
second off time for one on time for two
seconds off time for 1 seconds let's see
how it works and adjustment for you so
we can see the really outpost which is
controlled by the timer compact is
turning on for 2 seconds then drop off
over seconds and then turn now for two
seconds and drop off for one sex do this
kind of behavior for whatever time we
hold in the coils here as well as we key
energize it the timer contact goes off
so it's our discrete output
so he is coming here that's when I say
kill call you it goes off
okay let's look at function I flasher
you need to impress to start/stop so
this is physically and also asymmetrical
flasher what is like a impulse control
so we need a impulse on the command call
you're here to start this kind of
asymmetrical flashing behavior that we
need to energize reset coil to stop it
so let's try in simulation mode as we
can see function has been search
function
I press to start stop so that's
simulated we gave the command call your
impulse now we can see that timer
contacts start to do asymmetrical
flashing only if we energize recent call
you need to stop try again
don't stop it we have to energize
recycle
