General safety information and precautions
The following safety precautions are intended as a general guideline for using the PLC together
with other equipment. These precautions must always be observed in the design, installation
and operation of all control systems.
PCAUTION:
Training Manual GX IEC Developer III
쎲
Observe all safety and accident prevention regulations applicable to your
specific application. Installation, wiring and opening of the assemblies, com-
ponents and devices may only be performed with all power supplies discon-
nected.
쎲
Assemblies, components and devices must always be installed in a shockproof
housing fitted with a proper cover and protective equipment.
쎲
Devices with a permanent connection to the mains power supply must be inte-
grated in the building installations with an all-pole disconnection switch and a
suitable fuse.
쎲
Check power cables and lines connected to the equipment regularly for breaks
and insulation damage. If cable damage is found, immediately disconnect the
equipment and the cables from the power supply and replace the defective
cabling.
쎲
Before using the equipment for the first time check that the power supply rating
matches that of the local mains power.
쎲
Residual current protective devices pursuant to DIN VDE Standard 0641 Parts
1-3 are not adequate on their own as protection against indirect contact for
installations with positioning drive systems. Additional and/or other protection
facilities are essential for such installations.
쎲
EMERGENCY OFF facilities pursuant to EN 60204/IEC 204 VDE 0113 must
remain fully operative at all times and in all control system operating modes.The
EMERGENCY OFF facility reset function must be designed so that it cannot
cause an uncontrolled or undefined restart.
쎲
You must also implement hardware and software safety precautions to prevent
the possibility of undefined control system states caused by signal line cable or
core breaks.
쎲
All relevant electrical and physical specifications must be strictly observed
and maintained for all the modules in the installation.

1 Course Overview and Requirements
This course has been specially produced as an introduction to Mitsubishi’s FX family utilising the
GX IEC Developer software package.
The course content has been selectively produced to provide an introduction into the functional-
ity of the Mitsubishi range of FX PLC’s, together with the GX IEC Developer programming sys-
tem. The second section deals with the PLC hardware configuration and operation, whilst the
remainder covers the use of Mitsubishi’s IEC61131-3 programming system, which is illustrated
using worked examples.
It is assumed that student will have a sound working knowledge of the Microsoft Windows oper-
ating environment.
1.1 Modular PLC Training Hardware
There are various models of training rigs for Mitsubishis FX family. Most exercises within this
training manual are based around use of the facilities offered in these training systems. The
examples used in these course notes assume the following configuration:
쎲6 Digital input simulator switches: X0–X5
쎲Variable clock input (1 to 100 Hz and 0.1 to10 kHz): X7
쎲6 Digital output LED indicators: Y0–Y5
쎲1 Special function block FX2N-5A with 4 analog inputs and 1 analog output
쎲1 Temperature acquisition special adapter FX3U-4AD-PT-ADP
Thus, adjustments according to other training simulators may be accommodated with appropri-
ate address alterations to the example code provided this training document.

2 The Hardware
2.1 General Introduction to PLCs
2.1.1 History & Development
Bedford Associates, founded by Richard Morley introduced the first Programmable Logic Con-
troller in 1968. This PLC was known as the Modular Digital Controller from which the MODICON
Company derived its name.
Programmable Logic Controllers were developed to provide a replacement for large relay based
control panels. These systems were inflexible requiring major rewiring or replacement when-
ever the control sequence was to be changed.
The development of the Microprocessor from the mid 1970’s have allowed Programmable Logic
Controllers to take on more complex tasks and larger functions as the speed of the processor
increased. It is now common for PLC’s to provide the heart of the control functions within a sys-
tem often integrated with SCADA (Supervisory Control And Data Acquisition), HMI (Human
Machine Interfaces), Expert Systems and Graphical User Interfaces (GUI). The requirements of
the PLC have expanded to providing control, data processing and management functionality.
2.1.2 The initial specification for the PLC
쎲Easily programmed and reprogrammed in plant to enable its sequence of operations, to be
altered.
쎲Easily maintained and repaired – preferably using ‘plug-in’ cards or modules.
쎲Able to withstand the rigorous Environmental, Mechanical and Electrical conditions, found
in plant environments.
쎲Smaller than its relay and “discrete solid state” equivalents.
쎲Cost effective in comparison with “discrete solid state” and relay based systems.
2.1.3 Comparison of PLC and Relay Systems
The Hardware General Introduction to PLCs
Training Manual GX IEC Developer 2 - 1
Characteristic PLC Relay
Price per function Low Low - If equivalent relay program uses more than 10 relays
Physical size Very compact Bulky
Operating speed Fast Slow
Electrical noise
immunity Good Excellent
Construction Easy to program Wiring - time consuming
Advanced instructions Yes No
Changing the control
sequence Very simple Very difficult – requires changes to wiring
Maintenance Excellent
PLC’s rarely fail Poor - relays require constant maintenance

2.1.4 Programming
Ladder Logic
PLC’s had to be maintainable by technicians and electrical personnel. To support this, the pro-
gramming language of Ladder Logic was developed. Ladder Logic is based on the relay and
contact symbols technicians were used to through wiring diagrams of electrical control panels.
The documentation for early PLC Programs was either non existent or very poor, just providing
simple addressing or basic comments, making large programs difficult to follow. This has been
greatly improved with the development of PLC Programming packages such as Mitsubishi’s
Windows based, GX Developer.
Until recently there has been no formal programming standard for PLC’s. The introduction of the
IEC 61131-3 Standard in 1998 provides a more formal approach to coding. Mitsubishi Electric
has developed a programming package, “GX IEC Developer” (Covered in detail later in this
document.). This enables IEC compliant coding to be adopted.
2.1.5 Human Machine Interfaces
The early programmable logic controllers interfaced with the operator in much the same way as
the relay control panel, via push-buttons and switches for control and lamps for indication.
The introduction of the Personal Computer (PC) in the 1980’s allowed for the development of a
computer based interface to the operator, these where initially via simple Supervisory Control
And Data Acquisition (SCADA) systems and more recently via Dedicated Operator Control Pan-
els, known as Human Machine Interfaces (HMI). It is now common place to see PLC’s heavily
integrated with these products to form user friendly control system solutions.
Mitsubishi offer a very wide range of HMI and SCADA products to suit a variety of operator Inter-
face applications.
