Ever asked yourself what is the PlC or what are the trip codes? Many people always hear such terms but still, they know nothing about them.
In this article, we will tell you more about the PLC and more additional information about this world.
So what is a PLC?
It is an industrial computer that uses engineering for the automation of processes and its purpose is to help the machines develop all the systems that compose it effectively. Thanks to these benefits, PLCs have become a fundamental tool for the technological development of industries and the entire environment.
What is the operation of the PLC?
The operation of the PLC is based on periodic and succession processes. Next, we will explain a sequence of these devices.
⦁Self-diagnosis: It is the revision of all the circuits. In the event of a problem, the device indicates a signal.
⦁Input reading and recording: Evaluates each input to diagnose whether it is in an on or off state and records these processes in memory, establishing an image.
⦁Reading and carrying out the program: Using the image found in memory, the computer carries out the program instructed by the user.
⦁Registration and updating of outputs: In this step, all outputs are simultaneously restored.
Some characteristics of PLCs:
⦁ Control inputs and outputs safely
⦁ They have programming that is compatible with different languages
⦁ Ability to connect to supervision systems
⦁ Ability to run the schedule continuously
⦁ The memories are divided into two parts
In which industries is the PLC used?
As we commented previously, in the market there is the availability of PLC according to the need for automation that the industry requires.
We provide a reference list of business sectors that have used these robots, multiplying the efficiency of their systems and saving costs.
⦁ Companies dedicated to the processing of cement and sand
⦁ Plastic manufacturers
⦁ Wood industry
⦁ Security and transportation companies
⦁ Installation of air conditioning and heating
⦁ Automobile and tire industries
⦁ Oil and chemical companies
⦁ Energy companies
⦁ The real estate industry
Types of PLC for industry
In general, the automation is classified into a compact, modular, narrow band, low band, rack mount, industrial computer, software, and slot.
In today’s market, there is a wide range of PLCs available for every automation need, the most recognized for their quality and safety being those manufactured by the Siemens and Allen Bradley brands. The first enjoys dominance in the Asian market, as well as the European one, and the second has hegemony in the United States. In relation to the other continents, both brands are receptive to their products.
We present a list of the most demanded PLC models of these two technological powers for the industrial area.
Siemens: S7-200, S7-300, S7-400, S7-1500. Each of these models has accessories available that will be useful to optimize automation processes in industries.
Allen Bradley: Large PLC Control Systems, Small PLC Control Systems, Process Controllers, Micro PLC Control Systems. Like Siemens devices, these devices have accessories.
