Controlling Pneumatic system with plc

                             PLC COUNTER CONTROLLING SYSTEM 

In this system we  use pneumatic two cylinder and plc . PLC is use to control the two
2 solenoid valve and get data from the 3 proximity sensor

HOW IT IS WORKING ;
   In this system we use 3 proximity sensor , when we press the push button the cylinder is advancing
when it is advancing the sensor is indicate after indicating sensor other cylinder is start to working
when second cylinder advancing and retract ten time  the plc all ways counting the advancing and retract action. when plc 10 time counting its stop the pneumatic system

pneumatic counter practical with pneumatic cylinder

                                pneumatic counter practical

In this practical we use

1. Double acting cylinder
2. 5/2-way solenoid valves
3. 3 inductive proximity sensor 
4. relay counter 

in this practical we start the  cylinder with electrical push button . then the cylinder start the working

as result of this cylinder action the sensor sens and then start the other cylinder working after counting 5 stroke the two cylinder stop their action
