PROGRAMMABLE LOGIC CONTROLLER

INTRODUCTION:
PLC (Programmable Logic Controller) is one of electronic
equipments. It was called “Sequence Controller” before. It was named
“Programmable Logic Controller (PLC)” by NEMA (National Electrical
Manufacture Association) in 1978 and defined as electronic equipment.
The operation of PLC is in the following:
Step 1: Read the external input signal, such as the status of keypad, sensor,
switch and pulse.
Step 2: Using microprocessor to execute the calculations of logic, sequence,

timer, counter and formula according to the status and the value of the input
signal read in the step 1 and pre-write programs saved inner to get the
corresponding output signal, such as open or close of relay operation of
controlled machine or procedure to control automatic machine or procedure
of manufacture.PLC also can be used to maintain and adjust of production
program by editing or modifying the peripheral equipments (personal
computer/handheld programming panel).The common program language of
PLC is ladder diagram.
There are stronger functions in PLC with the development and application
requirements of electronic technology, such as position control, network and
etc. Output/Input signals are DI(Digital Input),AI(Analog Input), PI(Pulse
Input),DO(digital Output),AO(Analog Output) and PO (Pulse Output).Thus
PLC plays an important role in the feature industry.
THE MICRO PLC OFFERS FOLLOWING FEATURES:
 Compact and Economical

 Easily mountable DIN rail or Back panel mounting
 High speed counter input up to 5KHz
 Variety of function block and powerful instruction set.

The Working Principles of Ladder Diagram:
Ladder diagram is an automatic control diagram language that

developed during World War II. At first, it just has basic components,
such as A contact (normally open), B contact(normally close),output
coil, timer counter and etc.(The power panel is made up of these basic
components).It has more functions, differential contact, latched coil
and the application commands, add, minus, multiply and divide
calculation, that traditional power panel can’t make since PLC is
developed.
The working principles of the traditional Ladder Diagram and
the PLC Ladder Diagram are similar to each other, the only difference
is that the symbols for the traditional ladder diagram are expressed in
the format that are close to its original substance, while those for the
PLC ladder diagram employ the symbols that are more explicit when
being used in computers or data sheets. In the Ladder Diagram
Logics, it could be divided into the Combinational Logics and the
Sequential Logics, and is described as follows:
1. COMBINATION LOGICS:
The following example is the combination logics that show in
traditional diagram and PLC ladder diagram separately.
Traditional Ladder Diagram PLC Ladder Diagram

X0
Y0 X0
Y0
X1 X1
Y1
Y1
X2 X4
X4
X2 Y2
X3 X3 Y2

Example 1: Circuit 1 utilizes one X0(NO: Normally Open)

switch, which is normally known as the “A” switch or contact, and
its characteristic is that the contact is in the OFF condition at
regular time (not pressed): the output point Y0 is thus in OFF
condition, However, once the switch motion (the button is pressed)
is contact will be ON, and the output point Y0 will be in ON
condition.
Example 2 : Similarly, Circuit 2 utilizes the X1 (NC: Normally

Closed) switch, which is normally known as the “B” switch or
contact, and its characteristic is that the contact is in the ON
condition at regular time; the output point Y0 is thus in ON
condition. While the switch motion is conducted (which is in the
OFF condition), the output Y0 is in OFF condition.
Example 3: This is an example of combination logics output,

which has more than one input equipment. The output point Y2
will be in ON condition when X2 is in OFF condition or X3 and
X4 are in ON condition.
2. SEQUENTIAL LOGICS:
The sequential logics are a type of circuit that possesses the
“Draw-Back” structure, which is to draw back the circuit’s output
result and has it serve as the input condition. Thus, under the same
input condition, different output results will be generated in
accordance with previous conditions and motions with different
orders.
The following example is the sequential logics that show in traditional
diagram and PLC ladder diagram separately.
Traditional Ladder Diagram PLC Ladder Diagram
X5 X6
Y3 X5 X6
Y3
Y3 Y3

When the above circuit is just supplied with power, although the
X6 switch is ON, the X5 switch is still OFF, Thus, the output relay Y3
will be in OFF condition; output of the relay will only be ON after X5
is ON. Once the output relay Y3 is in ON condition, there will be a
feedback signal containing the ON condition from Y3 to connect in
parallel with the A contact of X5; this circuit is thus also known as
the self-latched circuit. The circuit motion is showed in the following
chart:
Device Status
X5 X6 Y3
Step
1 N N OFF
2 Y N ON
3 N N ON
4 N Y OFF
5 N N OFF
N: is in OFF condition Y: is in ON condition
From above chart, you can find that the same input may get different
result. For example, in the step 1 and 3, the status of X5 and X6 are in OFF
condition but Y3 is in OFF condition in step 1 and in ON condition in
step3,that is due the self-latched circuit feedback input. In this example, it
explains with contact A, contact B and output coil. The usage of other
equipment is the same with this. please refer to the chapter 3 for the detail.
