previously we went through the
0:05
step-by-step process of designing and
0:07
programming a Click PLC airport baggage
0:10
claim machine this covered everything
0:12
from setting up the PLC to writing the
0:14
code it did not matter whether you're a
0:16
beginner or an experienced programmer
0:17
the method used was ideal for anyone
0:19
seeking to enhance their PLC programming
0:21
skills the airport baggage belt was one
0:24
of many machines in the machine
0:25
simulator MS also known as Easy PLC this
0:29
baggage belt claim features sensors to
0:31
determine the size of the bag and
0:33
directs it down one of two different
0:34
ramps we discovered that the sensor for
0:37
the large bags required modification
0:39
adjusting the click PLC ladder logic
0:41
enabled us to make this machine work
0:43
temporarily we'll now show you how to
0:45
optimize airport baggage handling with
0:47
sensor and PLC tweaks implementing these
0:49
simple yet effective changes you will
0:51
see how easy it is to work with the
0:53
machine simulator learning PLC
0:55
programming is now easier than ever with
0:57
minimal investment required so if you're
0:59
ready to take your airport's baggage
1:00
handling to the next level continue

there will be links to the rest of the
1:20
videos in this series as well
1:24
modification of sensor position
1:27
start the Nerk Studio machine simulator
1:29
we will modify the sensor for the large
1:31
bags in the airport baggage machine
1:33
select editor on the main menu click on
1:35
factory 1 this is where the
1:38
pre-programmed airport baggage machine
1:40
was programmed you will know this
1:42
because of the background in the machine
1:47
the machine editor will now load and be
1:49
displayed for factory 1
1:52
select open from the main menu chakshu
1:55
file under the load machine file window
1:58
a list of all of the machines for this
2:00
machine editor will be displayed select
2:03
airport baggage.mmaq and then select
2:08
our airport baggage claim will now be
2:10
loaded inside the machine editor
2:13
we can navigate this 3D environment to
2:16
locate the sensor that needs to be
2:17
modified for our system as we touch
2:20
objects we can move them with our mouse
2:30
click one of the three arrows and drag
2:32
to the new desired location
2:36
select our exit sensor to detect large
2:38
bags on the main conveyor
2:53
the properties will be displayed on the
2:55
right hand side of the machine editor
2:58
under rotation in the properties change
3:00
the middle value to 270
3:04
this represents the rotational degrees
3:05
and will put the sensor at a 90° angle
3:10
our large bag will no longer be sensed
3:12
when moving to the main conveyor
3:14
to confirm we will also relocate the
3:16
sensor slightly to the left from the
3:17
exit to the main conveyor use the arrow
3:24
quick manual trial of new sensor
3:28
while still in the machine simulator
3:29
editor select the play button located at
3:32
the top middle of the screen
3:34
this will allow us to manually control
3:36
the airport baggage claim scene by
3:38
clicking the output buttons on the left
3:40
and watching the input button on the
4:02
you will now see that as we manually
4:04
test our system our sensor is not
4:06
triggered by the large bag exiting onto
4:10
at any time during these manual
4:12
movements we can pause the action this
4:14
can help us fine-tune our system
4:17
select the stop button at the top of the
4:19
screen to return to the editor
4:23
select save from the main menu new file
4:28
a warning message will be displayed
4:30
informing us that the machine screenshot
4:32
already exists update it select yes
4:36
this is the picture that you see as you
4:38
scroll through all of the pre-built
4:39
machines for you to program select exit
4:42
from the main menu yes file confirm that
4:46
you want to exit we will be returned to
4:48
the main screen of the machine simulator
4:55
machine simulator connection to our
5:01
open machines in the machine simulator
5:03
software this can be done from the
5:04
machines icon in the top menu of the
5:06
main page or by selecting open machine
5:11
all of the pre-built machines will be
5:20
select the start of the airport baggage
5:22
machine this will load our modified
5:27
the status of the machine simulator will
5:29
be at the bottom left of the screen
5:32
currently we have no PLC connected
5:36
select IO drivers at the top of the
5:38
screen the machine simulator IO number
5:41
will be displayed ensure we select more
5:43
I/O than required for our baggage belt
5:47
the easy PLC driver is selected by
5:49
default under the driver pulld down menu
5:51
select Modbus driver this driver
5:54
supports Modbus TCP Ethernet and Modbus
6:00
select the configure button
6:04
we can now enter the information for our
6:06
Modbus driver just as we did last time
6:08
select TC IP this means the Ethernet
6:11
port on the computer will communicate
6:15
the digital inputs from MS to the click
6:16
PLC will be C101 to C107
6:20
this will start at address 16484 due to
6:24
digital outputs from MS to the click PLC
6:30
this will begin at address 16584 due to
6:34
select the okay button you will now see
6:37
the inputs and outputs specified for the
6:42
we can now manually assign the driver
6:44
outputs to the PLC inputs and the driver
6:46
inputs to the PLC outputs
6:49
however the automatic assignment works
6:51
well and will save you time select
6:53
automatic assignment from the driver
6:55
option in the main menu
6:58
this will automatically assign the PLC
7:00
IO to the machine simulator IO
7:03
select start driver and exit from the
7:09
on the bottom left side of the window
7:11
the driver communicates with the click
7:17
select view IO to know the input and
7:19
output status of the machine simulator
7:23
click PLC program modification
7:28
call up the click PLC program that we
7:32
ensure that we are connected to our
7:34
click plus PLC and the status of the
7:37
inputs and outputs are shown
7:40
scroll down to rung 14
7:45
this will show the photo 7 sensor that
7:46
we just modified in the machine
7:50
currently we use a leading edge oneshot
7:53
to determine if other bags are currently
7:54
on the main conveyor belt
7:57
we will now change this to a normally
7:59
open contact this will now be the same
8:01
logic as the small bag
8:14
save the project by selecting this from
8:16
the main menu your file write the
8:20
project to our click PLC
8:44
call up the data view setting from last
8:47
we can monitor the inputs and outputs
8:49
from our click PLC programming software
8:53
change the PLC mode to run from stop
9:02
our PLC modified ladder logic is now
9:04
running with our modified airport
9:06
baggage claim machine

returning to our machine simulator we
9:33
can now monitor our modifications to
9:35
ensure they function as expected
9:39
previously our sensor picked up the
9:40
large bag before it left the conveyor to
9:42
the main this caused us issues and we
9:44
tried to compensate this location by
9:46
using a oneshot in the ladder logic
9:49
our modified program sensor location now
9:51
allows the large bags to be placed on
9:53
the conveyor without hitting others that
9:55
are already on the main conveyor
9:58
did you know that an estimated 64
10:00
million bags are mishandled each year at
10:01
airports imagine the chaos that could be
10:03
avoided with automation
10:06
you can now see how simple sensor and
10:08
program tweaks can help with this using
10:11
a machine simulator ms to test the
10:13
program will ensure that our program
10:15
works troubleshooting is quickly done

without damage to any physical hardware
