3 A Brief Introduction to PLC Designer
3.1 What is »PLC Designer«
»PLC Designer« is a complete development environment for your PLC.
»PLC Designer« puts a simple approach to the powerful IEC language at the disposal
of the PLC programmer. Use of the editors and debugging functions is based upon the
proven development program environments of advanced programming languages
(such as Visual C++).
3.2 Overview of PLC Designer Functions...
3.2.1 How is a project structured?
A project is put into a file named after the project. The first POU (Program
Organization Unit) created in a new project will automatically be named PLC_PRG. The
process begins here (in compliance with the main function in a C program), and other
POUs can be accessed from the same point (programs, function blocks and functions).
Once you have defined a Task Configuration, it is no longer necessary to create a
program named PLC_PRG. You will find more about this in the Task Configuration
chapter.
There are different kinds of objects in a project: POUs, data types, display elements
(visualizations) and resources.
The Object Organizer contains a list of all the objects in your project.
3.2.2 How do I set up my project?
First you should configure your PLC in order to check the accuracy of the addresses
used in the project.
Then you can create the POUs needed to solve your problem.
Now you can program the POUs you need in the desired languages.
Once the programming is complete, you can compile the project and remove errors
should there be any.
