Description

Unlock the power of Structured Text (ST) – one of the most powerful and widely used high-level programming languages in the world of PLCs. Whether you're already familiar with Ladder Logic or Function Block Diagrams (FBD), this course will take your PLC programming skills to the next level. The course starts from scratch and is ideal for beginners. The instructor is using CCW (Connected Component Workbench) as a software tool to teach Structured Text programming along with Micro850 PLC for download and testing the software.

If you do not have a PLC, you can practice directly on the CCW PLC Simulator which is free to download.


Why Structured Text?

Structured Text makes it easier to implement advanced logic, reusable code, and powerful automation routines. It's ideal for complex industrial applications where Ladder and FBD fall short.

Whether you're a beginner or transitioning from Ladder diagram or FBD, this course will give you the confidence and skills to write professional-grade PLC programs in Structured Text.

Structured text is widely used most of the widely used PLC Brands like Allen Bradley, Siemens (SCL as modified form of ST), CODESYS, Omron, Schneider, Delta, WAGO etc.


Tools & Software Used

  • Free IEC 61131-3 compliant PLC programming software with Structured Text editor

  • Built-in simulator for testing without hardware

Who this course is for:

  • Automation engineers looking to upgrade their programming skills
  • Students and beginners who want to learn Structured Text from scratch
  • Technicians familiar with Ladder or FBD who want to transition to text-based programming
  • Anyone interested in modern, scalable, and efficient PLC software development
