Programmable Logic Controller: A Boon to Technological and Human Advancement

By Paul M. Marshall

The programmable logic controller was developed in response to the need for a more efficient manufacturing method as well as a way to streamline the overall process without having to start from scratch every time there was a change. Essentially, this is a device that was designed to take the work of manually re-wiring devices or re-developing processes by hand and allow for things to be done quicker and take the burden of the work off of the employees, who could then tend to other, less repetitive, tasks.

Something else to keep in mind with the programmable logic controller is that it´s also designed to deal with environments that are inhospitable to more sensitive equipment. This could include factories where there is a lot of mechanical vibration, loud noise, or things like dust, heat, or even condensation. The idea here is that this device will work no matter what the environment, so that production will not drop. It is designed to keep going no matter what.

Of course, the question regarding programmable logic controllers now becomes if they´re so great, won´t that take away from jobs that were previously done by other people? The answer in this case is, in fact, no. The reason for this is that while a programmable logic controller is designed to do its task no matter what, if things change, it will need to be re-programmed or re-configured. And this can only be done by someone that is familiar with this type of device.

So while on one hand it might seem that it takes away jobs that were previously done by people, it also opens up an entirely new category of employment because there´ll always be a need for people that know how to deal with this type of device. This could include things like manually fixing the device if there´s a problem as well as re-programming it to handle additional tasks or to handle a sudden change in the manufacturing process.

One final thing to consider when thinking about it programmable logic controller is that while it can be configured to work in any type of environment and can also be reconfigured to adapt to changes, it is a relatively straightforward and simple device. There are two reasons for this: the first of course is that if it´s overly complex then no one will truly understand how to deal with any problems that might arise, let alone how to configure it properly. The other thing to think about is that by keeping it simple, the less chance there is of a malfunction or a catastrophic failure occurring. Of course, the complexity depends on the type of job that the device is being configured for. However, if its purpose is kept relatively simple, then there will be less potential problems with the device once it has been configured.

The programmable logic controller has allowed for not only a streamlining of the manufacturing process but has also allowed for a reduction in overall labor costs and training as well as an increase in the efficiency of the company that uses them. Something else you might want to consider is that with this device taking away the more mundane tasks with respect to manufacturing, it has in fact allowed technology and creativity to flourish and move forward.
