Pada kenyataannya PLC merupakan suatu mikrokontroller yang digunakan untuk keperluan industri. PLC dapat dikatakan sebagai suatu perangkat keras dan lunak yang dibuat untuk diaplikasikan dalam dunia industri.
Secara umum PLC memiliki bagian-bagian yang sama dengan komputer maupun mikrokontroler, yaitu CPU, Memori dan I/O. Susunan komponen PLC dapat dilihat pada gambar berikut :

Adapun Penjelasan dari komponen-komponen pada PLC adalah Sebagai Berikut :

  1. Central Processing Unit (CPU)
  2. CPU merupakan bagian utama dan merupakan otak dari PLC.
    CPU ini berfungsi untuk melakukan komunikasi denngan PC atau Consule, interkoneksi pada setiap bagian PLC, mengeksekusi program-program, serta mengatur input dan ouput sistem

  3. Memori
  4. Memori merupakan tempat penyimpan data sementara dan tempat menyimpan program yang harus dijalankan, dimana program tersebut merupakan hasil terjemahan dari ladder diagram yang dibuat oleh user. Sistem memori pada PLC juga mengarah pada teknologi flash memory. Dengan menggunakan flash memory maka akan sangat mudah bagi pengguna untuk melakukan programming maupun reprogramming secara berulang-ulang. Selain itu pada flash memory juga terdapat EPROM yang dapat dihapus berulang-ulang.
    Sistem memori dibagi dalam blok-blok dimana masing-masing blok memiliki fungsi sendiri-sendiri. Beberapa bagian dari memori digunakan untuk menyimpan status dari input dan output, sementara bagian memori yang lain digunakan untuk menyimpan variable yang digunakan pada program seperti nilai timer dan counter.
    PLC memiliki suatu rutin kompleks yang digunakan untuk memstikan memori PLC tidak rusak. Hal ini dapat dilihat lewat lampu indikator pada PLC.

  5. Catu Daya PLC
  6. Catu daya (power supply) digunakan untuk memberikan tegangan pada PLC. Tegangan masukan pada PLC biasanya sekitar 24 VDC atau 220 VAC. Pada PLC yang besar, catu daya biasanya diletakkan terpisah.
    Catu daya tidak digunakan untuk memberikan daya secara langsung ke input maupun output, yang berarti input dan output murni merupakan saklar. Jadi pengguna harus menyediakan sendiri catu daya untuk input dan output pada PLC. Dengan cara ini maka PLC itu tidak akan mudah rusak.

  7. Rangkaian Input PLC
  8. Kemampuan suatu sistem otomatis tergantung pada kemampuan PLC dalam membaca sinyal dari berbagai piranti input, contoh senseor. Untuk mendeteksi suatu proses dibutuhkan sensor yang tepat untuk tiap-tiap kondisi. Sinyal input dapat berupa logika 0 dan 1 (ON dan OFF) ataupun analog.
    Pada Jalur Input terdapat rangkaian antarmuka yang terhubung dengan CPU. Rangkaian ini digunakan untuk menjaga agar sinyal-sinyal yang tidak diinginkan tidak langsung masuk ke dalam CPU. Selain itu juga rangkaian ini berfungsi sebagai tegangan dari sinyal-sinyal input yang memiliki tegangan kerja yang tidak sama dengan CPU agar menjadi sama. Contoh Jika CPU menerima input dari sensor yang memiliki tegangan kerja sebesar 24VDC maka tegangan tersebut harus dikonversi terlebih dahulu mendai 5VDC agar sesuai dengan tegangan kerja CPU.

  9. Rangkaian output PLC
    Suatu sistem otomatis tidak akan lengkap jika sistem tersebut tidak memiliki jalu output. Output sistem ini dapat berupa analog maupun digital. output analog digunakan untuk menghasilkan sinyal analog sedangkan output digital digunakan untuk menghubungkan dan memutuskan jalur, misalnya piranti output yang sering dipakai dalam PLC adalah motor, relai, selenoid, lampu, dan speaker.Seperti pada rangkaian input PLC, pada bagian output PLC juga dibutuhkan suatu antarmuka yang digunakan untuk melindungi CPU dari peralatan eksternal. Antarmuka output PLC sama dengan antarmuka input PLC.
  10. Penambahan I/O PLC
    Setiap PLC pasti memiliki jumlah I/O yang terbatas, yang ditentukan berdasarkan tipe PLC. Namun dalam Aplikasi seringkali I/O yang ada pada PLC tidak mencukupi. Oleh sebab itu diperlukan perangkat tambahan untukmenambah jumlaj I/O yang tersedia. Penambahan jumlah I/O ini dinamakan dengan expansin Unit.

Waktu Scan
Proses pembacaan dari input, mengeksekusi program dan memperbaharui output disebut scaning. Waktu scan umumya konstant dan proses sekuensial dari pembacaa status input, mengevaluasi logika kontrol dan memperbaharui ouput. Spesifikasi waktu scan menunjukkan seberapa cepat kontroler dapat bereaksi terhadap input.
Faktor Waktu Scan
Faktor Yang Mempengaharui Waktu Scan
Waktu yang diperlukan untuk membuat suatu scan bervariasi antara 1 milidetik sampai 30 milidetik. Waktu scan tergantung dari panjang program. Penggunaan subsistem remote I/O juga menaikkan waktu scan karena harus mentransfer I/O update ke subsistem remote. Monitoring dari kontrol program juga menambah waktu overhead dari scan karena harus mengirim status dari coil dan contact ke peralatan pheriperal.

Product Revision Information
RSLogix Emulate 5000 Version 16.00.00 requires the following:

Software Product Compatible Versions:
RSLinx 2.51.00 or higher
Any RSLogix 5000 version from Version 12 through 16

Installation Procedure
Product Installation:
Begin the installation of the product by running the setup.exe file
located at the root of the CD media. This will launch a CD browser that
provides a means to install the RSLogix Emulate 5000 product, and
also displays pertinent product information.

Please use the “Add/Remove Programs” applet in control panel to remove
previous versions of SoftLogix5800. While performing an install or uninstall,
please note any messages that recommend a system reboot. Failure to follow
the reboot instructions can render your installation inoperable.

If you want to reinstall the same vesion as is currently installed, please use the
“Add/Remove Programs” applet in control panel to remove the existing version of
RSLogix Emulate 5000. While performing an install or uninstall, please note any
messages that recommend a system reboot. Failure to follow the reboot instructions
can render your installation inoperable.

Please refer to the RSLogix Emulate 5000 Getting Results Guide for details on
installing this product. This document can be viewed with the Adobe Acrobat
Reader by opening the file LGEM5K-GR016A-EN-P.pdf located at
\Documentation on the RSLogix Emulate 5000 CD.

IMPORTANT NOTES:
RSLogix Emulate 5000 cannot be installed on any machine that already has
SoftLogix5800 installed on it.

RSLinx Classic should be installed before installing the RSLogix Emulate 5000
product.

If RSLinx Classic is installed after RSLogix Emulate 5000, please run the
SIRegEDS.exe program that can be found in the RSEMU5000 directory on the
installation CD. After the products are installed, you must first add the
Virtual Backplane driver in RSLinx Classic in order to connect to the
SoftLogix engine.

Even if you plan to remotely program the controller over a ControlNet or
Ethernet link, you must add the Virtual Backplane driver via RSLinx Classic
software. If you do not, persistent storage will not function and when you
reboot the computer, the controller will come up with cleared memory (the
program will not get re-loaded).

Data Execution Prevention (a feature of Microsoft Windows also known as DEP) is
not supported by RSLogix Emulate 5000. If your computer’s CPU supports DEP, we
advise using DEP for only essential Windows programs and services. (This is the
default setting for Windows XP; for Windows Server 2003, DEP is on by default
for all programs and services.) If DEP is turned on for RSLogix Emulate 5000,
you may experience unexpected results. See your Windows documentation for
information regarding DEP.

Jump to Subroutine (JSR) instructions do execute in the emulator. However,
the instruction passes parameters to subroutines in reverse order from the
order in a physical controller (the last parameter is passed first in an
emulated controller). Do not use JSR instructions in a manner where the
order in which parameters are passed to a subroutine matters.

Dibawah ini ada beberapa links, jika anda tertarik untuk belajar PLC Siemens. Silahkan cek dan downloada filenya. Semoga Bermanfaat

—————————–

This is a listing of tutorials and manuals found on the Siemens automation website that will get you started on the SIMATIC Step 7 software for S7-300 and S7-400 systems. From a new users perspective I’ve only heard disparaging comments about finding the right information on the Siemens’ website. I have to agree. Its information overload at it’s best. There’s a lot of different stuff there thrown together and found in different spots with very long URL addresses to add to the confusion.

Have no fear. We’re here to help. So we’ll look at the essentials for your journey.

  • The software if you haven’t got it yet
  • Getting a sense for the product line
  • Where to start with the manuals
  • Online training material
  • Downloadable Flash tutorials

Of course the best type of training is the hands on type but if that’s not an option then you’ll need to start digging in.

Who’s got the Software?

If you are just learning and can’t easily get the software then there are two options.

  1. Order the demo CD which will give you a free 30-day trial period.
  2. Download a free working copy of Step 7 Lite. There are differences between the regular version of Step 7 and Step 7 Lite but for learning purposes you can go along way with the free Lite version.

First Things First

The first thing I like to do with a new product is get an overview of everything. Getting used to part numbers and product groupings can go a long way with your comfort level. The best thing for this is the sales catalog (ST 70 – 2005). You can also order a hard copy.

Where to Start? Manuals, manuals, everywhere!

Once you install the Step 7 software there will be a directory under the SIMATIC folder called Documentation that includes the most important manuals. Hard copies can be ordered with number 6ES7810-4CA08-8BW1. Here’s how I would digest them.

  1. Working with STEP 7 – This is a basic introduction to Step 7 which walks through an example of controlling engines. While it’s not the complete picture it does ease you very well into the learning curve of the Step 7 software.
  2. Programming with STEP 7 Manual – Here’s the fuller manual for the programming interface which is also the same as the online help accessed by pressed the F1 key.
  3. Configuring Hardware and Communication Connections STEP 7 Manual – Everything to do with the Hardware Configurator.
  4. Statement List, Ladder Logic, and Function Block Diagram Reference Manuals – These manuals contain both the user’s guide and the reference description of the programming language or representation type. You only require one language type for programming an S7-300/S7-400, but you can mix the languages within a project, if required. If you’re more comfortable with Ladder Logic or Function Block Diagram then start there but sooner or later you’ll have to become familiar with Statement List.
  5. System Software for S7-300 and S7-400 System and Standard Functions Reference Manual – The S7 CPUs have integrated system functions and organization blocks included with their operating system, which you can use when programming. This manual provides you with an overview of the system functions, organization blocks, and loadable standard functions available in S7, and detailed interface descriptions for their use in your programs.

Training Material

There’s gold in that website if you just do a little digging! If you’re having a tough go with the manuals then you should definitely download the training material. There’s a lot more screen shots and even a picture of a balding pudgy guy to point things out to you. What more could you want?

Flash Tutorials

If you’re not the manual type (and even if you are) check out the Siemens Step 7 Flash tutorials. These are very professionally done with a nice sounding narrator to take you through all the basics of the Step 7 software and hardware.

What’s Next?

Of all the starting places to dig for more info I find the support section the best especially if you have a part number or key word you can search on. Clicking on the Product Support link will bring up a tree on the left hand side that can be expanded down to the product of your affection. Good luck and happy hunting.
