Chapter 5, Problem 19RQ
Program Plan Intro
Programmable Logic Controller (PLC):
- Programmable Logic Controller (PLC) is a specialized computer used in industrial segments to control machines and process.
- PLC is programmable that consists of a set of instructions which resembles the controlling functions needed to perform specific tasks.
- The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC.
- When compared to general Personal Computer (PC), a PLC is available in small and tiny sizes.
- The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that run by control
programming language.

- 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 1 ON OFF ON ON 3 OFF ON 4 OFF 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.
