Mitsubishi Electric MELSEC iQ-F Series Installation guide

FX5U Training Manual

The PLC is activated by command inputs such as inputs from pushbutton switches, selector switches
and digital switches located at the operating panel, and by sensor inputs, such as inputs from limit
switches, proximity switches and photoelectric switches, which detect the status of the system, in order
to control drive loads such as solenoid valves, motors and electromagnetic clutches, and indication
loads such as pilot lamps and digital indicators.
The behaviors of output signals corresponding to the input signals are determined by the
contents of programs provided to the PLC.
Light loads such as small solenoid valves and pilot lamps can be directly driven by a PLC, but loads
such as 3-phase motors and large solenoid valves must be driven through contactors and intermediate
relays.
As well as PLCs, contactors, intermediate relays and circuit breakers for the power supply are installed
in the control box.

The Definition of a PLC
A programmable Logic Controller (PLC) is referred to as a Programmable Controller
(PC) or Sequence Controller (SC).
A PLC is dened as "an electronic device which controls many types of systems through
its I/O ports and incorporates a memory to store programmable instructions."
Actual Usages
PLCs are broadly used as core components for FA (Factory Automation) and as electronic
application products essential for saving labor costs and improving automation.
PLCs can be used for many types of applications such as systematical applications
which supply control all over a factory or as standalone applications to control an
independent machine.

Mechanism of PLC
The PLC is a microcomputer for industrial purposes.
A PLC incorporates an electrical circuit mainly comprised of a microcomputer and memory.
Input/output interfaces exist between input/output devices and the electronic circuit to connect them.
The programming panel is used to write a program to the memory in the PLC.
The term "sequencer"
In Japan, the term "sequencer" is widely used. While Japan Electrical Manufacturer's Association
(JEMA) ofcially names them Programmable Logic Controller (PLC), the name "sequencer" seems
easier to pronounce and more widely known.
Though there is evidence that the term "sequencer" was used before PLCs were invented.

The PLC can be, in effect, considered as an aggregate
of relays and timers.
The PLC is an electronic device mainly comprised of a microcomputer.
However in effect…
The user does not need any knowledge of a microcomputer to operate a PLC and it can be regarded
as an aggregate of relays, timers, and counters.
Signal Flow of PLC
● When the pushbutton switch PB1 is pushed, the coil of the input relay X1 is
energized.
●When the coil of the input relay X1 is energized, the N.O. contact of X1 is closed and the
coil of the output relay Y0 is energized.
●When the coil of the output relay Y0 is energized, the contact of Y0 is closed, then the
pilot lamp PL is illuminated.
●When the pushbutton switch PB1 is released, the coil of the input relay X1 is de-energized
and the N.O. contact of X1 is opened.
But the output relay Y0 is still energized since the N.O. contact is closed. (Self-maintaining action)
●When the input relay is energized by closing the limit switch LS1, the N.C. contact of X3 is
opened, then the coil of the output relay Y0 is de-energized (Reset).
As a result, the pilot lamp; PL distinguishes and the self-maintaining action of the output
relay Y0 is cleared.

As shown below, a PLC incorporates multiple relays, timers and counters with countless N.O. and N.C.
contacts.
A sequential circuit is formed by connecting the contacts and coils.
Also, one advantage of using a PLC is that a lot of storage cases called "data registers" are included.
