Today, you can observe that most facilities, equipment and machines an industrial company use are all modernized and that is through the effort sand support of the engineers, programmers and technicians. But, that is not the only change that you can see in those companies, they also have a more advanced and sophisticated electrical system. Therefore, you must not only be an engineer by title or profession, instead you have to be a skilled and an expert in the field of electrical as well as automation systems, who can work on a PLC.
Most high-tech companies today use PLCs or Programmable Logic Controller and it would be difficult for an individual to understand this system without proper knowledge and certification. Do you know that a PLC system is used in power or electrical system automations and that electrical engineers must be working on it? That is why we need PLC experts, who will train and mold our engineers in such a way, they can be competitive and confident with their work. Luckily, we have companies, that offer this kind of services and you may visit one at onlineplcsupport.com.
The PLC Principle
A PLC is a device that industrial companies used in their control system. This device has an exceptional function when it comes to the counters or timers, programming, controls and the use of hardware. It acts like a specially designed computer or machine. For the PLC to properly work, you have to understand the uses or functions of its three modules.
One of the modules is the CPU or the Central Processing Unit, where you can find the memory and the processor. Another module is the Power Supply Module, which is, of course, in-charged with supplying power to the system, such as the CPU and the Input/Output modules. While the I/O Module could be a digital or an analog I/O, which is used in connecting the actuators as well as the sensors, so that the PLC system can sense the pressure, temperature and flow of the system.
The PLC operates through a scan cycle. It will first monitor the time. The second step is for the CPU to read the data coming from the I/O and check the status of the I/O. The third step would be for the CPU to execute the PLC program. After that, the CPU will diagnose and communicate with the system. And then, expect an output, depending on the program or task. Those steps completes the cycle of the PLC operation. You may click here to know more about how a PLC works.
The Electrical System
When it comes to the installation of the electrical system used in the automation of a PLC, this must be inspected by licensed electricians or electrical support teams. They need to approve the installation first before an operator or any member of the team starts using the system or machine. Proper inspection means that the electrical team knows the rules or protocols of the PLC system and they know everything about the functions and controls.
It is very important for this electrical system to be carefully inspected. They need to make sure that safety protocols are built to be ready for automation. Through this support, automation and electrical are controlled and workers will be protected from any electrical accident that may happen because of power as well as equipment failures. If possible, we have to prevent the system from those failures because it may affect the production of the company. We surely do not want such things to happen, right?
Can you see how important it is to manage the electrical power system in the manufacturing and industrial companies? Anyway, it would be great if you can read more about how this concept works. We have here a good example that you may find at https://waset.org/publications/9999896/concept-of-automation-in-management-of-electric-power-systems. Through this link, you can understand more how important it is for power systems to be monitored and inspected rationally.
The Automation System
Support from the electrical engineers and the IT experts is needed in the automation system of a PLC. They need to work as a team to come up with the program of the electrical hardware design of the Programmable Logic Controller. They need to develop and install this hardware, too. After that, they need to test it for safety purposes and make sure that the whole system is functioning according to the program written or given instruction. If this works right or the program was executed without errors, then the system was correctly programmed.
The teams will not only work on the PLC as a whole. They must also know about the MPS or Machine Interlock or Protection System, how to control the supply of power to the magnets located in the storage rings, PSS or the Personal Safety Systems, amount of WAT or the water cooling system and VENT or ventilation systems that the beam lines and rings need. So, if you will notice, an electrical engineer plays a very important role in the automation system. Without their help and support, then a programmer alone may not be able to accomplish the process correctly and safely. This is the reason why electrical controls are carefully inspected and checked.
Electrical Controls Support and Services
Now, if you are going to hire electrical control expert, then you have to provide the list of hardware needed as well as the manual of your automation or PLC program. They will use this to create the blue-print of the control cabinet. And then, they will connect the cables that your control system and they will make sure that the I/O functions properly.
Again, through these people your safety is considered. In my opinion, it is not good to just keep on producing and manufacturing goods without considering the safety measures in the workplace. Can you imagine how much damage it would cost your company, if the electrical system was not properly installed? You should know how risky it is working with electrical machines and equipment, having high voltage. In such a way, you will treat this issue seriously.
