SOFTWARE TESTING


We have test the ladder diagram with the cx-programmer. The program only can simulate in window XP and we simulate and checking the program sequences before move to the PLC memory.

HARDWARE TESTING

The I/O connection is checked before the actual PLC operation is carried out. The model is constructed according to the draft that we have draw.

Initial testing the system

Checking the I/O connecting before actual run

Pneumatic cylinder use for lifting operation

Battery use for motor operate 

Inductive sensor use for detect metal and non-metal sensor

Two cylinders use for sorting operation

Through-beam sensor use for detect the object before lifting operation

Diffuse-reflective sensor use to detect object for next "stamp" operation

Pneumatic value for control cylinder operation

INPUT AND OUTPUT CONNECTION DIAGRAM 

We using 24V dc supply for this project, the input and output device is connecting accordingly with the address that we have decided.


LADDER DIAGRAM

The ladder diagram will send to PLC to perform the instruction respectively and above is one part of the program and for full ladder diagram please email me.

SYSTEM DESCRIPTION

There are two same object, one with metal casing and vice versa. First and foremost, the system will detecting the object before going the "stamp" process. Next, the inductive sensor will sense the casing of the object and there are piston A and piston B where piston A will operate if the object casing is metal and piston B will operate if the object casing is non-metal. These two piston will only operate after lifting process. Apart from that, we using another piston for lifting purpose and the process will run again when the sensor detect object in initial state.

1. Start

2. Detect object

3. Stamp process

4. Object is metal -- Piston A operate

5. Object is non-metal -- Piston B operate

6. Object exists on lift

7. Lifting

8. End

PLC PROJECT - 1

PROJECT DESCRIPTION

In this project, we are using the programmable logic controller (PLC) to combine the inputs and outputs in order to design a sorting and processing system.


The inputs and outputs include as below:


A. Push button
B. Limits switch
C. Mechanical switch 
D. Proximity sensor
E. Inductive sensor
F. Cylinder
G. DC motor
H. Light
I. Buzzer


The brand of the PLC that we used in this project is OMRON CQM1H, while the software used to test the designed program is CX-programmer.
