Detail Weighing Machine using PLC

Weighing Machine
Information on Numbers for Weighing Machine using PLC :
1. Weighing with input / output external
2. Sensor Object with an infrared receiver and transmitter
3. Indicator Lights for the Empty
4. Indicator Lights for Weighing Not OK
5. Indicator Lights for Weighing OK
6. Electric Motor
7. Sensor for empty containers
8. Sensor for detection position of the Rotary container
9. Input / Output external Weighing :
=>9a. Output Weighing : GO/OK
=>9b. Input Weighing : Digital Zero Reset


Number Of Inputs and Output PLC applied :
1. Number Of Inputs PLC is 4 Input :
--- 1 Unit Input from Sensor Object (NO:2)
--- 1 Unit Input from Sensor for empty containers (NO:7)
--- 1 Unit Input from Sensor for detection position of the Rotary container (NO:8)
--- 1 Unit Input from Output Weighing : GO/OK (NO:9a)
--- Total Number Of Inputs PLC is Minimum 4 Input Unit.

2. Number Of Output PLC is 5 Output :
--- 1 Unit Output to Yellow Lights for the Empty (NO:3)
--- 1 Unit Output to Red Lights for Weighing Not OK (NO:4)
--- 1 Unit Output to Green Lights for Weighing OK (NO:5)
--- 1 Unit Output to Contactor for Electric Motor (NO:6)
--- 1 Unit Output to Input Weighing : Digital Zero Reset (NO:9b)
--- Total Number Of Outputs PLC is Minimum 5 Output Unit.


Sequence PLC Programming for Weighing Machine:

1. Weighing with value 7.0 => OK
2. Weighing with value not 7.0 => NOT OK
a. If Sensor Object (NO:2) = ON Then wait for 2 seconds AND Green Lights, Red Lights = OFF
b. After 2 seconds Then Digital Zero Reset (NO:9b) = ON AND wait for 0.5 seconds
c. After 0.5 seconds Then Electric Motor (NO:6) = ON
d. If Sensor Rotary container (NO:8) = ON Then Electric Motor (NO:6) = OFF
e. Wait for 5 seconds
f. After 5 seconds :
==>If Weighing : GO/OK (NO:9a) = ON Then Green Lights (NO:5) = ON
==>If Weighing : GO/OK (NO:9a) = OFF Then Red Lights (NO:4) = ON

3. Empty Containers
a. If Sensor for empty containers (NO:7) = OFF Then Yellow Lights (NO:3) = ON
b. If Sensor for empty containers (NO:7) = OFF AND Sensor Object (NO:2) = ON Then Green Lights, Red Lights = OFF AND All Process OFF
