In today's fast-paced industrial world, automation has become a key element that helps companies increase efficiency, improve safety and reduce costs. At the heart of these automation processes are PLCs (Programmable Logic Controllers), which are the brains behind most modern industrial systems. In this article, we take a look at how these programmable logic controllers work, the benefits of using them, which industries use them, and discuss the different types of PLCs, including the PLC range from JUMO. Check it out!
A PLC (Programmable Logic Controller) is an electronic device used to control industrial processes. The operating principle of a PLC is based on reading input data from various sensors, processing them according to a programmed algorithm and then generating the appropriate output signals to control machinery and equipment.
The programmable logic controller is used to control the operation of a machine or other industrial equipment. It can also be used to control production lines, lighting or other electrical equipment.
PLC controllers consist of several basic components:
Depending on the model and manufacturer, a PLC controller may have additional features or components such as built-in touchscreen displays (e.g., JUMO vaRITRON 500 touch), memory card slots, USB ports, etc.
PLCs can have additional functions or components, such as the built-in touchscreen on the JUMO variTRON 500 touch
Working with PLC controllers offers many advantages, such as:
Furthermore, PLC controllers are characterized by low energy consumption and an exceptionally high level of reliability compared to older systems based on relays and contactors.
They are more advanced than relay-contactor systems, which required physical changes in wiring for alterations in control functions. An advantage of PLC controllers is that we can easily change how they control systems by modifying the controller's program, rather than changing intricate wiring. This results in significant simplification and a reduction in the time associated with modifying the control of a given installation.
By using PLC controllers, you also don't need additional devices like time relays or auxiliary contactors, enabling you to save on equipment and installation costs.
One of the main advantages of working with PLCs is the automation of complex industrial processes
PLC controllers are widely used in various industrial sectors, such as:
In each of these cases, the application of PLC controllers in industrial automation contributes to increased efficiency, enhanced safety, cost reduction, and error minimization. This translates to improved performance and competitiveness for businesses.
One of the applications of PLCs is the construction of industrial furnaces and the control of their operation
There are several basic types of PLC controllers available on the market:
These are small, single-module devices that have all the elements of a PLC controller integrated, i.e., the central unit (CPU), memory, communication interfaces, and input/output modules. Due to their size and cost, they are ideal for simple or moderately complex automation tasks.
Example: The compact PLC JUMO variTRON 300 is such a device. This central unit can function as a receiver for the wireless JUMO wTrans sensors.
These are more complex devices consisting of separate modules (CPU, input/output modules, communication interfaces, etc.) that can be freely configured. This gives them great flexibility and allows them to be adapted to the user's specific needs. They are typically used in more intricate automation systems.
Example: JUMO variTRON 500 serves as an example. It's a central unit with a PLC controller according to IEC 61131-3 (CODESYS V3.5) combined with proven input and output modules.
These are the most advanced and efficient PLC controllers, typically mounted in cabinets and consisting of a series of modules mounted in racks (or chassis). They can handle large numbers of inputs/outputs and are frequently used in large industrial systems requiring substantial computational power and intricate control logic.
These are PLC controllers that run on a standard PC or industrial PC, using special software to simulate the operation of a traditional PLC. Soft PLCs offer many of the advantages of traditional PLCs, such as flexibility and efficiency, while also providing increased capabilities, such as easy integration with other computer systems.
Remember, choosing the right PLC controller depends on various factors, such as function requirements, the number of inputs/outputs, communication requirements, and more. When selecting a PLC controller, it's a good idea to consult with an experienced supplier, like JUMO, who can assist you in picking the right solution for your specific application.
Using PLC controllers can significantly improve production, increase efficiency and safety, and reduce the risk of errors. That's why they are indispensable in many industrial sectors.
JUMO mTRON T PLC central processing unit and modules
PLCs play a key role in modern industrial automation, enabling companies to increase efficiency, improve safety and reduce costs. Thanks to their flexibility and ability to control a variety of processes, PLCs have found their way into a wide range of industrial sectors, from plant engineering to the food industry to energy and water supply.
The JUMO range, including the JUMO variTRON 300, JUMO variTRON 500 and JUMO variTRON 500 touch, MTRON demonstrates how diverse and versatile these devices can be. Whether you need a compact controller for simple applications or an advanced system with the possibility of connecting additional modules, JUMO has something to meet your requirements.
In the era of digitalisation and Industry 4.0, PLCs are not only essential, they are the key to the future of industry. Therefore, it is worth understanding how they work and how they can contribute to the success of your business.
