Codesys Structured Text Example

A DUT is a special object that allows the definition of a Structure. In order to improve testing, we have prepared special tools to control the inputs/outputs of the controller and to make appropriate settings. But as you are undoubtedly aware, there are several other "paradigms" (programming languages) out there to create logic, and you want to program competently with them all. The editor is very simple to use and supports all five languages defined in the standard: Ladder Logic (LD), Function Block Diagram (FBD), Instruction List (IL), Structured Text (ST), and Sequential Function Chart (SFC). The CODESYS Group is the manufacturer of CODESYS, the leading hardware-independent IEC 61131-3 automation software for developing and engineering controller applications. Moreover, CoDeSys combines the capabilities of high-level programming languages such as C or Pascal with the simple handling and the functionality of a PLC programming system. Using the freely-available* software tool CoDeSys, which is widely used in industrial design automation projects, the author takes a highly practical approach to PLC design using real-world examples. A PLC is an example of a "hard" real-time system since output results must be produced in response to input conditions within a limited time, otherwise unintended operation will result. Two example programs with a different implementation (object oriented in ST and graphical in CFC) are provided together with this library. All five programming languages for application programming defined in the IEC 61131-3 are available in the CODESYS development environment. If you're coming from the Allen-Bradley world then obviously Ladder Diagram is going to be your most comfortable language, but I expect you'll also want to make use of Structured Text.
