2.2 CODESYS V3
CODESYS is a software platform designed to handle many tasks of industrial automation technology. It is
based on the IEC 61131-3 programming system. The tool benefits users with integrated solutions tailored to
their practical work and aimed at providing hands-on support with whatever job needs to be done.
CODESYS supports all five languages specified in IEC 61131-3 (International Electrotechnical Commission):
IL (Instruction List)
ST (Structured Text), based on PASCAL for structured programming
LD (Ladder Diagram)
FBD (Function Block Diagram)
SFC (Sequential Function Chart)
Apart from the standard IEC languages, CODESYS also supports:
CFC (Continuous Function Chart) is a FD (function diagram) editor with a fully configurable graphical
layout: whereas FD editors are network-based and automatically arrange the function blocks, CFC
lets users place the blocks anywhere such that feedback effects can be created without any
temporary variables. This feature makes the language the perfect choice for creating an overview of
the application.
2.2.1 Fieldbus technology
The CODESYS programming system allows the direct configuration of the CANopen and EtherCAT, OPC
UA and Modbus fieldbuses. Protocol stacks can be separately installed as CODESYS libraries for some
systems.
