PLC is the user
friendly, for the microprocessor which is based on the micro-computer for the
software and the hardware to control the operation of the process and
equipment. The advantage of a PLC is it is easily programed and reprogrammed.
On the industrial control; the PLC has the tremendous impact as well on the
instrumentations because it has the flexibility and the reliability for the
implementation design stages. Some manufactures of PLC are ABB, Honeywell,
Siemens, and Mitsubishi. PLC architecture
is dependent on the three areas, that is processing, input/output, memory .The
input instruction is depending on the
programming of the PLC , and the output are generated , for the associated
devices in the output/input actions. Now the below figure 2 shows the
architecture of the PLC that consist of output/input, for the communications
modules and the memory unit.
To perform the
work, the reason is to use the pneumatics machine, as the work requires for the
application of kinetic energy for the resisting objects that is moving through
the distance. In the pneumatics systems, the energy is stored as the potential
states for the compressed air conditions. From the atmosphere the compressor
pumps the air, into a receivers, to reduce the volume as well as pressure level
is raising. [3] The pneumatics is
the systems which is used for the compressed air and control the energy , where
the pneumatics systems is used to control the doors of train; automatic
production lines .
