•Rockwell Automation was initially founded in 1903 by LyndeBradley & Stanton Allen.

•February 20, 1985 Rockwell Automation purchased Allen-Bradley.

•Developed to replace relays in the late 1960s.

•PLC began in the 1970s, and has become the most common choice•PLC began in the 1970s, and has become the most common choicefor manufacturing controls.

•Costs dropped and became popular by 1980s.

• Now used in many industrial designs.

Operation condition:-

1. There are two lights only red and green.

2. If green is on then red will be off, and other three red will

Example 1:-- traffic light

2. If green is on then red will be off, and other three red will

be on.

3. Every green light should be on only for 5 seconds.

Example2 :-- Conveyor Overload

Operation condition:-

1. When sensor 1 is on,counter1 counts the items passing through sensor 1 sensor 1

2. When sensor 2 is on,counter2 counts the items passing through sensor 2

3. If the number of items is more than 10,the alarm will blink which will indicate that the conveyer is overloaded

• SCADA refers to “Supervisory Control and Data Acquisition”.

• These are real time industrial process control systems used to centrally

monitor and control remote or local industrial equipment such as motors,

valves, pumps, relays, etc.

• Worked on Factory Talk View SE Programming software.

Examples related to INDUSTRIES

EXAMPLE 1:- FAULT DURING PROCESS

OPERATION CONDITION:-

1. ALARM blinks when there is fault is present.1. ALARM blinks when there is fault is present.

2. If ACKNOWLDGE button is pressed, alarm only glows.

3. If RESET button is pressed and fault is cleared then alarm off.

OPERATION CONDITION:-

1. When START button is pressed Motor 1(M) starts after

5 sec, it will remain start for 20 sec.5 sec, it will remain start for 20 sec.

2. Motor 2(c) starts after 25 sec, after pressing the

button.
