It will tell you how to use RSLogix and how to write a ladder logic program. Since I feel the best way to learn any programming language is by using a real-world example, there is a sample project included in this book.
This sample project, which involves a chemical batching process, also contains a Project Scope. The Project Scope, or Functional Specification, or whatever your company might call it, defines in detail how the system is to operate when the project is finished. The book will show you how to go online with your PLC to monitor your program to verify your ladder logic and make sure it is functioning properly.
It will show you how to make changes to your program while you are online. It will show you the keystrokes and mouse movements that you need to know to use RSLogix Finally, it provides a number of tips and a Frequently Ask Questions section that will save you hours of frustration. This book assumes you have a little background with PLCs — perhaps you have worked with other PLCs from other manufacturers or you have helped to install and wire PLCs.
This ebook, along with the online tutorial, provides an example of how to automate a drill press, while explaining all the basic concepts of PLC programming that are necessary to write a solid PLC program. In addition, it provides an example of machine operation, whereas this book uses the example of a chemical batching process. Visit engineer-and-technician. PLCs Nearly all the industrial equipment that you find in a modern manufacturing facility shares one thing in common - computer control.
The language was developed to make programming easy for people who already understood how switches, relay contacts and coils work. When you are finished with this book, you will be able to sit down in front of any computer running RSLogix and create a new program.
You will be able to edit existing programs. You will be able to professionally document any changes you have made. There are just too many variables. This is why you must establish a relationship with your local Rockwell Automation technical support team. Get to know them before you are in the final stages of a start-up and you run into a problem.
They are very helpful and they can save you hours of frustration. The Rockwell reps are not just technical support personnel; they are skilled engineers that are responsible for running their own projects and writing and troubleshooting their own programs. If you run into a problem, more than likely they have already seen it and have come up with a solution. For our application, the L55 processor will be fine. For your future projects, you will have to consider a number of factors before you make the choice of your processor.
All the processors use RSLogix , so any program you write for one processor could be adapted to run any other processor. Admittedly, the software is a bit pricey, but in my opinion, it is worth it. The demo runs for 90 days, and has some limitations, but you will be gaining experience with the real thing.
There are 7 sections to download, totaling slightly over MB. I have summarized the basic terms and techniques required to work with ladder logic. Every PLC programmer, no matter what skill level, must know the principles described in this section and the Equivalent Logic section.
There is simply no way around it. To effectively write a program, or even edit one, the programmer must know how to visualize the effects of the changes he will make. An XIC it looks like a normally open contact --] [-- is an instruction. A timer is an instruction. A few of the most common instructions are described below.
It can be an input, output or internal coil, among others. Just like in an electrical ladder diagram, a rung has some type of output that is turned on or turned off by the preceding entities in the rung. The first rung in a ladder program is always 0. RSLogix defines the address of the input, based on the input cards that you configure.
Here is where some confusion comes in. Because the Rockwell numbering system starts with 0, and the processor resides in Slot 0, our example bit is actually in slot 5. Our bit 3 is actually the 4th bit. You will have to learn to transpose these ways of describing a bit back and forth in your head. If you are troubleshooting a problem, and you want someone to look for a signal on our example bit, you might have to tell him to look at the 4th position on the 5th slot.
That will lead him to the physical point on the PLC. However, you need to keep in mind that the corresponding bit in your program will be labeled LocalI. It can be confusing, but you will get used to it. Outputs are addressed the same way. The internal coil has no connection to the outside world. It does not connect to an output card. Internal coils are used to store information. RSLogix has greatly simplified the process of describing an internal coil.
We can simply give it a name, known as a tag. Note the lack of spaces in the tag name. RSLogix does not allow spaces, or other special characters, in the tag name. Either way is fine; it just depends on what your company or your client prefers.
TIMER A timer is a programmable instruction that lets you turn on or turn off bits after a preset time. Timers in RSLogix use tag names for identification. There are different types of counters available in the RSLogix, but the CTU counter up instruction covers everything we will talk about here.
Counters in RSLogix use tag names for identification. An XIC instruction can reference a hardwired input, a hardwired output, an internal coil or a timer done bit, among others. When used with a hardwired input, this instruction is "true" until there is a voltage applied to the input.
If it is used as an internal coil, it will toggle the instructions associated with it. That is, it will close a normally open instruction and open a normally closed instruction. An OTE may be used with a hardwired output or an internal coil. Also, if the logic in a rung turns on the output of the rung, then the rung is said to be true. In its elementary form, PLC logic is very similar to the hard-wired logic you would find in an electrical ladder diagram.
For example, if you wanted to turn on a light with a momentary pushbutton, you would wire it like the circuit below. When you press PB1, the pilot light PL1 lights up. In RSLogix , the screen would look like this. Therefore, the PL1 output is off. Pressing PB1 will make LocalI. It will stay on only as long as you hold the button in. Batching, as you may know, is the term that describes the mixing of assorted ingredients to make a finished product.
There are techniques that are common to batching, whether you are making soap or cake mix. We are going to write a program that mixes a hypothetical window cleaner. Someone has to define the batching procedure.
Usually, this is done by a process engineer or a chemical engineer. If the job of defining the project is done well, a document called a Project Scope or something similar is generated.
It is extremely important that you clearly understand the entire process that is defined in the scope. If you have any questions or concerns, you need to resolve those before you begin programming. If you bring up questions that result in changes to the defined sequence of operations, ask the originator to revise the Project Scope. In fact, it is not uncommon for a Project Scope to undergo a number of revisions. If there is a change that is not documented in the scope, you should document it by getting an email from the originator that explains the change.
If nothing else, you want to make sure you understand what the change involves. For our project, the project scope is as follows. After all the ingredients have been added to the Mixing Tank, the mixture is blended by running the agitator for a given time. When the blending time is complete, the finished product is pumped to the Filling Lines for bottling and final packaging. All other input signals are VAC. All output signals are VAC.
Detailed Sequence of Operations There are 5 steps in the Batching process: 1. No further operator input is required.

Пятнадцать секунд спустя экран ожил. Сначала изображение на экране было смутным, точно смазанным сильным снегопадом, но постепенно оно становилось все четче и четче. Это была цифровая мультимедийная трансляция - всего пять кадров в секунду. На экране появились двое мужчин: один бледный, коротко стриженный, другой - светловолосый, с типично американской внешностью. Они сидели перед камерой наподобие телеведущих, ожидающих момента выхода в эфир. - Это что еще за чертовщина? - возмутился Джабба. - Сидите тихо, - приказал Фонтейн.
Помимо всего прочего, в списке очередности указано, что это посторонний файл. Надо звонить Стратмору. - Домой? - ужаснулся Бринкерхофф. - Вечером в субботу. - Нет, - сказала Мидж. - Насколько я знаю Стратмора, это его дела.
Веспа шла с предельной скоростью.
Вся эта концепция чем-то напоминала идею колонизации Марса - на интеллектуальном уровне вполне осуществимую, но в настоящее время выходящую за границы человеческих возможностей. - Откуда вы взяли этот файл? - спросила. Коммандер не спешил с ответом: - Автор алгоритма - частное лицо. - Как же так? - Сьюзан откинулась на спинку стула. - У нас внизу работают лучшие программисты в мире.
Беккер здесь… Я чувствую, что. Он двигался методично, обходя один ряд за другим. Наверху лениво раскачивалась курильница, описывая широкую дугу. Прекрасное место для смерти, - подумал Халохот.
Открыв полку над головой, он вспомнил, что багажа у него. Времени на сборы ему не дали, да какая разница: ему же обещали, что путешествие будет недолгим - туда и обратно. Двигатели снизили обороты, и самолет с залитого солнцем летного поля въехал в пустой ангар напротив главного терминала. Вскоре появился пилот и открыл люк.
К счастью для японской экономики, у американцев оказался ненасытный аппетит к электронным новинкам. - Провайдер находится в районе территориального кода двести два. Однако номер пока не удалось узнать.
