Overview

GF_ProjectVX code is an IEC61131-3 Integrated Development Environment supporting the whole range of languages defined in the standard.

In order to support the user in all the activities involved in the development of an application, GF_ProjectVX code includes:

• • textual source code editors for the Instruction List (briefly, IL) and Structured Text (briefly, ST) programming languages (see Chapter 6);
  • graphical source code editors for the Ladder Diagram (briefly, LD), Function Block Diagram (briefly, FBD), and Sequential Function Chart (briefly, SFC) programming languages (see Chapter 6);
  • a compiler, which translates applications written according to the IEC standard directly into machine code, avoiding the need for a run-time interpreter, thus making the program execution as fast as possible (see Chapter 7);
  • a communication system which allows the download of the application to the target environment (see Chapter 8);
  • a rich set of debugging tools, ranging from an easy-to-use watch window to more powerful tools, which allows the sampling of fast changing data directly on the target environment, ensuring the information is accurate and reliable (see Chapter 9).
