Existing setup of Implement a PLC project by converting a pneumatic circuit into a PLC controlled circuit

        A double-acting cylinder is to cycle continuously upon the pressing of a switch. The cylinder is of small bore (25 mm diameter) requiring a small flow rate to operate at the correct speed (60 cycles per minute).  The cylinder should return to the initial position when the push button is pressed again.  A 5/2-way directional control valve controls the double-acting cylinder.  A typical shift at the plants lasts 8 hours.

        The double acting cylinder contains the fluid chambers, where the pressures is used for the both to extend as well as retract a rod. The cylinders is far common which is used in the most common applications. The effective working area for the rod side, of a pistons is less than the other sides, where the double acting cylinder retracts faster and extend the less force for the retraction stroke.

Implementation of the PLC is divided in the different programme;

Ladder Diagram

Low level based on Boolean expression

Functional Blocks

The PLC programming, which is based for the ladder diagram; includes the programme in same manner, to drawing the switching circuits. Ladder logic diagram is converted into PLC for the ladder diagram; through conventions of the PLC ladder; [4]

    Above figure shows the Control of pneumatics circuits; as when the start button is pressed, the CR1 is latched and the solenoid wave is energized for the Valve of TA+ by change the positions of the valve of air for the cylinder in the forward stroke.

Further Analysis of Implement a PLC project by converting a pneumatic circuit into a PLC controlled circuit

        Now the further explanations is about the PLC based pneumatics punching machine; as design and fabrications for the automatic sheet metal of punching machine which is controlled by the PLC. The working principle is also explained, the structure of hardware for the systems. The automations of the punching systems, have the greater control for the whole process, where the system can replace the existing manual   feed for the punching machine. Through interfacing the PLC which is possible for the good result to increase the safety of worker, and reduced the manufacturing for the lead time to reduce the angular misalignments. This punching process help the mass productions as they represents the fastest for the efficient method to form the metal , to finished the punched product . The compressed air work by the help of pneumatics systems. The air which is available, is naturally invisible, odourless, and the tasteless. There are main three components which is used in this methodology, are loading cylinder; unloading, and the punching cylinder.  [5]

        Programming language is used as the ladder logic; to presents the programme for the graphical diagram that based on the circuit diagrams, of relay of logic hardware. Develop the programme logic and software controller PLC in industrials applications. The ladder logic diagram of the punching machine is shown as below;

Discussion  of Implement a PLC project by converting a pneumatic circuit into a PLC controlled circuit

        All the discussion is about the PLC project; that is converted into the manual pneumatics system to the controlled PLC systems. The Pneumatics circuit is shown in the above figure of setup sections of pneumatics, and the ladder diagram is shown in below section Implementations of PLC. All the objective and the aim of the project if fulfilled. Pneumatics provided the various types of the valve for examples, mechanical, electrical which help to understand the manual of the automatic process.
