Expert Solution & Answer
Chapter 1, Problem 14RQ
Explanation of Solution
Changing the process control operation in a relay-based system::
- • Instead of using a relay based system, the process control operation is more reliable and easy to process using a PLC based system.
- • In a relay system, whenever there is a change in the input field, there must be a change in the rewiring of input devices,
- • This input device may be temperature switches, pressure switches, or manual push buttons...

Draw a plc ladder diagram for blinking lights with start and stop button. Please help me with this. Thank you in advanced.
A PLC is used to control a single-axis robot, in which the axis is driven by a pneumatic cylinder.
An output signal to the pneumatic cylinder causes it to extend (ON state). When there is no
signal, the pneumatic cylinder retracts (OFF state). The gripper is an also driven by a pneumatic
cylinder. The gripper open position is an OFF state and the closed position is an ON state. In
order to perform a task, the following sequence of operations must be performed:
TH
Sequence No.
Аxis
Gripper
OFF
OFF

ON

OFF
The process begins when the start bush button is ON and a part triggers a limit switch. For
safety, an emergency switch is used to shut off the entire system. Design a PLC ladder diagram
for this application.
Explain in detail the architecture of a PLC system by exploring on I/O modules, CPU, power Supply and programming devices.
