This section related specially to all engineers or technicians that working with any kind of production line. With out knowing them well, we have always problems to do any job in good ways. As it was created for production lines, it's most use of it is in almost any factory and productions lines. Every body who has to work in this field (production lines) as a technician, maintenance team, production engineer or any kind of job who is related to production has to have a good knowledge about them. As we can see it every day, there is no production lines that in some how are not using PLC for their specific purpose. It is very hard if not impossible, to work in this field and not having a lots of contact with PLC some how to the certain level. Work market highly ask for the people who are able to work with PLCs. If you do not know it , you are loose almost big numbers of jobs offer around you. The need of huge quantity of any product in market, makes it impossible to do them by human hands and his capacities. As all we know the law of the market, is the base of any kind of production activities. The company that is not able to supply the material requested on time, will be out of business. You or some one like you have to guarantee this, with your knowledge and experience. When almost all the production machines are working with PLC in certain level, knowing them is the key of your success in this responsibility. It is more than 50 years that they are in market, bout regarding of their importance and popularities in production lines, there are not much out there to explain it in simple and friendly manner. Like all other things in market, the manufacturer will not harmonize their products with other company, so it makes it hard to learn all of them. Many want to make it seems so difficult that only a few can understand it. So they can control the flow of person who wants to start this job. Many have learned it during years of experiment and can not explain it to others in easy ways. Many wants to make fortune with teaching them. So for people that they need it for survival, there is not much. There are big companies that they offer you their learning courses, but you will be limited by their machines and technology, you do not have chance to change or learn more than they give it to you. Their training programs are divided in such a manner that each person can do only some part of it, so you are always depending to others for doing a job finished. Most of the training material and systems are in such a manner that they want you to accept many concept without really discuss them deeply. They decide how much you should know.
The people that working in this field, need to know many things in wild ways to be able to call it "they have the knowledge of it" .
To have what we are looking for, we should do several tings:
- We should know exactly : what it is, what he can do.
- Learning all about the bases, as precise as possible.
- Learn and study all possibilities in general concepts, as large as possible.
- make the connection between Macro and Micro.
- Prove, any thing is right in base, it should be right in all general cases.
We have to do these almost mental exercises because of characteristics that these "intelligent" devices have it. Like all other "intelligent" devices: they are intelligent as much as the person who use it. They all from us, so we need mentally ready to handle them. Actually the rest is very easy or not difficult. Who can do a lot with them and who has always problem and can not work with them properly, comes to the point of thinking or believing about them. Like in our normal lives there are some laws for doing every thing in this universe. We can say for them we should know and be sure about certain things like:
1. The instructions that must be performed. 2. The order in which those instructions are to be performed. 3. The fixed data required to perform the instructions.
For any simple thing in this world, we do all and much more than these every second. So like many other things in this world, we should learn what we know it. To have a good general base we added some pages that may be for many are very simple and low level, but for a few can be useful. Our main goal is to know :
- Base of Electricity with some simple examples and circuits.
- Base of electronic, what are main and most used circuits in electronic.
- What are logic Gates?
- What is PLC?
- PLC main important parts and hardwares.
- Numbering systems.
- Structure.
- How does it works?
- What is programming?
- PLC devices.
- Timers.
- Counters.
- Important practical experiences of others in practice.
Our possibilities are not equal with our wishes, but we try our best. We need your help too, send us your experiences, ideas, disapprovals,...
