Defining GE Fanuc PLC | GE IP
Definition:
PLC or also known as programmable logic control is a digital computer used in automation. PLC work real-time, that means they react immediately on the input they obtain. They are designed in such a way that they can withstand factory and industry pressure like tolerating noise and excessive vibration. Along with this a PLC program can take multiple inputs and can give multiple outputs at a time. Due to these reason from past few decades, usage of programmable logic control PLC has increased worldwide.
Why PLC program invented?
"Necessity is mother of invention" same is the case with invention of programmable logic controls. PLC was invented in somewhere between 1960s in America. Its invention was to facilitate USA automobile industries. There it successfully replaced hard wire control panels. With this it was observed that PLC can reduce time consumption and associated cost. Thus this increased its popularity and later on it made its way in other parts of the world.
History of PLC:
The first PLC was made by Bedford Associations of Bedford, Massachusetts in 1968. Dick Morley was the project manager who led this project successfully. Later on in 1977 due to its successful launch and usage, general electronics acquired modicum brand PLC. From there journey of the PLC continued to a German company AEG and then to French company Schneider Electric.
Programming of PLC's:
Today PLC programs are much advanced as compare to the PLC programs used before and after 1980s. Earlier PLC programming was done with specially purposed propriety terminals. These panels contained dedicated operating keys. Today most of the PLC programming is done mostly with the help of software. Programming software is uploaded on personal computer and then they are connected to PLC via Ethernet cable.
Uses of PLC:
- PLC provides system flexibility.
- It helps to reduce weight and cost of the overall project.
- It deals with overall automation processes.
- It is used to control machinery present in an industry.
- Due to its immense temperature tolerance and vibration, it is ideal to be used in amusements parks and heavy duty industries.
