Choosing the right controller for a machine is a challenging process that could be very difficult at times. We all know that advancement in technology brought us to the point where we’re finding new products every single month. Therefore, it is a daunting task to compare two controllers, especially if you want to see the perfect one for your applications.
It is essential to find a professional engineer that will help you find a perfect combination of function, price, and performance. You should have in mind that without comprehensive consideration to capacities and balancing requirements before you make up your account. You can choose Allen Bradley PLC training, to reduce the hassle of finding out.
Before you enter the training, you should find a way to meet performance requirements, primarily if you use a complex system. Choosing a wrong technology will reduce the possibility of success. You have to find a proper control solution that will meet your expectations and requirements.
We will present you which factors you should have in mind so that you can ensure to find appropriate PLC for your needs:
Most people, especially young companies, tend to choose affordable PLC made by the utterly unknown manufacturer. It would be crazy to follow this advice from above because selecting a lousy machine will only reduce the money out of the company’s pocket.
We live in the harsh financial environment, where companies and individuals tend to pass on the cheapest outcome. However, finding a PLC for a single machine is a daunting process and using a specific and unknown configuration, and design can only cause further problems.
You should choose a controller that can quickly expand and adapt to both performance and functionality to meet contracting, or expanding. It is crucial to find the one that will be sustainable for a long time.
If you choose a PLC that features positioning, discrete I/O, analog I/O, temperature communication and other control types, you will make the most out of your investment.

A first and most important consideration when it comes to PLC’s is processing power. You probably understand that machine control must have the ability to provide you with a required logic program promptly and accurately.
If you choose a PLC system that cannot deal with the possibility to check, analyze and control the given situation on time, then you will reduce the optimal performance of the system. The worst thing that could happen is to cause damage to the machine, product or operators.
At the same time, when you have an underpowered controller in the system, machine performance will reduce the engineering time and the possibility for the controller to do its job. Of course, everything depends on the environment, however, having less power than needed is something that you should avoid.
It is simple to find a controller that features gap between specified and required performance. Therefore, you should see a place in between so that you can make a valuable communication between sales and engineering. Even if you find over-specified PLC, it is better than choosing an underpowered version.
It doesn’t matter if you want to consider buying a PLC for setting the parameters of servo amplifier or to get data from sensors, you should choose the one, which is entirely available to a standard network connection. In today’s factory environment, the standard network connection is the must.
A PLC should effectively control most operations of the machine directly, or remotely, as recent trends indicate and tell us. The advancement in technology changed the way we perceive things around us, which is why exotic Fieldbus cables and direct wiring are not accessible anymore.
Instead of them, manufacturers use a feature that everyone understands: Ethernet. It is one of the essential components and mediums for connection so that you can obtain information from a wide array of outlets. At the same time, it will help you enable simple implementation of control without any additional hassle.
You don’t have to get frustrating headaches of making wiring into terminal blocks or creating cable terminations. Therefore, using Ethernet is not only more convenient than past ways, but it is a cost-effective too and less time-consuming.
You can find limitless possibilities when it comes to Ethernet network based on the manufacturer you wish to choose.
If you don’t know what Ethernet is, you can find more about it on this particular website: https://en.wikipedia.org/wiki/Ethernet
It is vital to find a PLC with durable components because each hardware failure will reduce the income and make issues in your company. There is no way that you can replace or fix a PLC system without paying the expensive price tag. At the same time, if some parts are too costly, then the best solution is to replace an entire PLC.
Product quality is a problematic topic because some machines that are more durable than standard ones are also more expensive. Therefore, they will have expensive components that could even die after a while, and you have to pay a significant price tag again, and again.
In simple words, we recommend you to find a PLC that will not be a weak link in the machine system. Of course, some failures will come eventually, and that is inevitable, but finding a PLC that feature components that will provide a minimum of downtime will increase the client’s and customer’s confidence.
Each controller comes with a warranty deal, so it is crucial to consider this factor before you make up your mind.
Choosing an expensive controller system for a more expensive machine is the worst thing that you can do. It is not a smart decision to spend too much money on it when you can find the appropriate price that could work for your income later.
We’ve mentioned above that it is a difficult decision, especially if you want to bring the price level to the point so that you can sell it later. Choosing a machine where PLC is 5% of the cost, will give you peace of mind and possibility to get a machine with 50% significant selling point than before.
