GX IEC Developer

GX IEC Developer is more than a powerful IEC 1131.3
programming and documentation package. It supports your entire MELSEC PLC implementation from the initial project planning to everyday operation, with a wealth of advanced functions that will help you to cut costs and increase your
productivity. The sophisticated program architecture comes with a range of new, user-friendly functions, including
structured programming and support for function libraries.

Top-down application architecture

During the planning phase GX IEC Developer’s structuring tools help you to organise your project efficiently: Use the intuitive graphical tools to identify and display tasks, functional units, dependencies, procedures and application structures. In addition to making your work easier, this also significantly reduces error frequency in later project stages.

Flexible implementation

In the engineering phase you then choose the programming language that best matches the structure of your project:
ST (Structured Text)
SFC (Sequential Function Chart)
LD (Ladder Diagram)
FBD (Function Block Diagram)
IL (Instruction List)

Program frequently-used functions in function blocks
and organise them in libraries. This gives you the confidence
that comes with knowing you are using tested, reliable
code. Password support helps you to protect your valuable
expertise.

Simple configuration of control components

Configuration of controller components is performed quickly and efficiently in tables with interactive dialogs and graphical support. And this powerful support is available for standard and special function modules as well as for the controller CPUs. You no longer have to create application programs to configure your system. Setting up the hardware and network configuration Powerful testing and debugging tools provide
information on the current status of the controllers and
the network you are connected to. Network functions like status and error displays, remote SET/RST functions for controllers and peripherals, Live List, Cycle Time, Connection State and more enable you to locate and correct errors quickly and get your hardware and networks up and running in record time.

Setting up the application program

GX IEC Developer comes with everything you need to get
your applications installed, set up and running as quickly as
possible, including comprehensive online programming functions, fast and informative monitoring displays, the ability to manipulate device values with the graphical editors,
manual and automatic step mode execution in IL, the
display of manipulated device values in the EDM (Entry Data
Monitor) and much more.

Normal operation

During normal daily operation you can also use GX IEC
Developer to display important system status information, either in standalone mode or called by another program in the control room. The automated SFC functions and the ability to display internal and external function block status
information simultaneously are particularly useful. This
provides a valuable additional view of the system, between
the functions of a straight code monitor and an animated machine representation.

Installation and maintenance

Top-down architecture, structured programming,
comprehensive printed documentation and support
for user-defined help for your function blocks all help to
c lear display of overall project structure reduce the learning curve. You can make the information needed for installing and maintaining the system available to the operators
quickly and efficiently, with minimum training overheads.
