LEARNING OUTCOME

MODULE 1
Introduction to PLC System

PLC - Introduction
 Historical Background
 PLC - programmable logic controller
 PLC implements logic control functions by
 means of a program

History
The Hydramatic Division of the General Motors Corporation
specified the design criteria for the first programmable
controller in 1968 Their primary goal.
To eliminate the high costs associated with
inflexible, relay-controlled systems
• The controller had to be designed in modular form, so that sub-
assemblies could be removed easily for replacement or repair.
• The control system needed the capability to pass data
collection to a central system.
• The system had to be reusable.
• The method used to program the controller had to be simple,
• so that it could be easily understood by plant personnel.

Development
1968  Programmable concept developed
1969  Hardware CPU controller, with logic
instructions, 1 K of memory and 128 I/O points
1974  Use of several (multi) processors within a PLC
- timers and counters; arithmetic operations; 12 K of
memory and 1024 I/O points
1976  Remote input/output systems introduced

Development
1977  Microprocessors - based PLC introduced.
1980  Intelligent I/O modules developed Enhanced
communications facilities Enhanced software features
(e.g. documentation) Use of personal microcomputers
as programming aids.
1983  Low - cost small PLC’s introduced.
1985  Networking of all levels of PLC, computer
and machine using SCADA software.

Discrete State Control

Example

State Diagram

State Diagram
State variables:
X1: pump;
X2: valve.
X1: X1=0: pump off
X1=1: pump on
X2: X2=0: valve is closed
X2=1: valve is open

State Diagram
1) Open the valve if it is closed and the level of liquid in the tank
is less than the desired level L (LLS=0), or keep the valve open
if LLS=0.
2) Close the valve if it is open and the level of liquid in the tank is
equal to or greater than the desired level L (LLS=1), or keep the
valve closed if LLS=1
3) Turn the pump on if it is off and the valve is open and LLS=0, or
keep the pump on if it is already on and the valve is open and
LLS=0
4) Turn the pump off if it is on and LLS=1, or keep the pump off if
LLS=1

LIVE WEBINARS
 Pelajar akan mendapatkan 12 sesi live interactive dengan
pengajar dan siswa lainnya dari daerah yang berbeda.
 Tiap webinar akan berlangsung selama 90 menit kemudian
dilanjutkan dengan sesi tanya jawab selama 30 menit.
 Yang pelajar butuhkan hanya koneksi internet yang memadai,
speakers dan sebuah microphone.
 Paket software dan cara setup akan dikirimkan sebelum
program dimulai. Hubungi kami untuk detail jadwal sesi
webinar.

FORMAT PRESENTASI
 Program bersertifikasi ini memuat aplikasi nyata di dalam
industry Instrument, Automation dan menggunakan
pendekatan yang melibatkan self-study, interactive online
webinars dan latihan tugas. Program ini terdiri dari 4 module,
dalam periode 3 bulan.
 Beberapa module akan melibatkan latihan praktek dan
aktifitas group.dalam module tertentu akan ada tugas
membaca disertai dengan pelatihan memecahkan masalah.
Para peserta akan mendapatkan bimbingan dari pengajar dan
koordinator kursus selama dalam program ini.
 Materi baca akan disampaikan dalam format electronic (PDF)
sebelum kelas (webinar) dimulai. Presentasi dan diskusi group
akan diadakan secara live dan menggunakan interactive
software system. Seluruh tugas akan dikirimkan dalam format
electronic dan jika memungkinkan, latihan praktek akan
menggunakan simulasi software dan remote labs

KEUNTUNGAN LIVE E-LEARNING
 Menghadiri kursus di dalam kelas secara online bersama pengajar
dan sesama pelajar.
 Meningkatkan kemampuan dan menambah pengetahuan anda
tanpa harus menyita waktu yang sangat berharga dan tanpa perlu
meninggalkan aktifitas rutin anda.
 Menerima informasi dan materi dalam format yang mudah untuk
dipelajari
 Belajar di dalam perjalanan – yang anda butuhkan hanyalah koneksi
internet.
 Mendapatkan dukungan penuh dari pengajar dan kordinator
program selama mengikuti kursus.
 Berinteraksi dengan teman sekelas dan instruktur perpengalaman
yang menambah networking di industry instrument & automation
 Belajar langsung dari praktisi ahli di bidangnya
 Live interaktif webinars, bukan hanya ‘book atau recording di dalam
web.

GROUP TRAINING
o Kami dapat menyediakan training / seminar di tempat yang
anda inginkan. On-site training dapat disesuaikan dengan
mendatangkan instruktur ke tempat dan waktu yang sesuai
dengan kenyamanan anda!
