Technical Articles & Industry Trends
With automation becoming increasingly critical in industrial settings, it is important to choose the right advancements for your specific use case. For people like manufacturing professionals, automation engineers, and IT specialists, understanding the nuances of PLCs and industrial computers is a critical part of maintaining a competitive edge.Â
A PLC is an industrial digital computer used in the automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or lighting fixtures. They read inputs from various sensors and devices, process the data, and control the state of outputs such as motors, valves, and other devices. Compared to general-purpose computers, PLCs are typically ruggedized, have much shorter scan times, and greater immunity to electrical noise. They are also designed to withstand harsh industrial environments and include extensive input/output (I/O) connectivity.Â
Advantages of PLCs
Limitations of PLCsÂ
Industrial computers are designed to operate reliably in harsh usage environments such as strong vibrations, extreme temperatures, and wet or dusty conditions. These computers often support applications that require excellent processes & graphics performance, as well as diverse I/O (input/output) features. They can be used for data acquisition and control, networking, and complex computing operations in various manufacturing segments, from automotive to pharmaceuticals.Â
Advantages of Industrial ComputersÂ
Limitations of Industrial ComputersÂ
To choose between a PLC and an industrial computer, manufacturing professionals must consider performance metrics, programming capabilities, as well as the systems' flexibility and scalability.
Performance Metrics
When it comes to speed, PLCs often have the upper hand with their high-speed I/O, designed for extremely fast responses. However, industrial computers are typically equipped with more advanced processors, which allow for superior performance in handling complex control and monitoring tasks.Â
Programming Capabilities
PLCs are associated with ladder logic programming, which is tailored to the needs of industrial control. While highly intuitive and efficient for control applications, it presents a learning curve for those familiar with standard programming languages used with industrial computers, such as C++ or Java.Â
Industrial computers, on the other hand, offer a broader range of programming options, which can be more familiar to IT specialists. This includes the ability to run a wider variety of third-party software for data analysis, manufacturing execution systems (MES), and other business-related software.Â
Flexibility and Scalability
PLCs win in system flexibility within their narrow application scope. They can be easily reconfigured for different functions or adjusted to new sensor types and numbers. However, this comes at the cost of scalability, as PLC systems tend to be more challenging to expand beyond their original scope.
Industrial computers, though starting with higher complexity, offer a more flexible base for scaling up with the addition of more powerful hardware or software upgrades. Their ability to integrate with standard networking protocols and equipment also makes them more scalable when it comes to expanding the scope of applications.
Teguar offers a wide range of customization options such as IP ratings, touch screens, wireless connectivity, and more. Thus, making it easier to tailor an industrial computer to meet the exact needs of a particular application or environment.Â
It is not a matter of which technology is better; it is a matter of which technology is more suitable for the specific manufacturing operation. At Teguar, our team works closely with clients to understand the requirements of their unique applications and recommends suitable hardware that can optimize processes.Â
Our range of industrial computer offerings caters to the diverse needs of manufacturing professionals, with products that are resilient, high-performing, and fully customizable to ensure seamless integration into your production environment.
Product OverviewÂ
Why Choose Teguar?
Choosing between a PLC and an industrial computer is a decision that requires a deep understanding of the manufacturing processes, the level of automation required, and the scalability of the system. While PLCs are the traditional choice for robust control in discrete industrial processes, industrial computers are gaining a foothold due to their versatility, processing power, and network capabilities.
For complex operations that demand high processing power or need to be integrated into a larger system, industrial computers may be the better choice. Teguar's expertise in industrial computer technology can guide manufacturing professionals to make the best choice for their unique requirements, ensuring that automation efforts are as efficient and productive as possible.
In the end, both technologies have their places in the manufacturing landscape. The key is to leverage their strengths for the greatest strategic advantage. Whether you're upgrading an existing system or designing a new one, Teguar is ready to help you make the right decision.
