Introduction to SCL Programming | Converting Ladder Logic to SCL (IF Statements)

Описание: This video continues Chapter 7 of the PLC Training Series, building directly on the previous lesson where we introduced Ladder Logic and the PLC Scan Cycle.

In this session, I take the next step by introducing Structured Control Language (SCL) in Siemens TIA Portal and demonstrating how Ladder Logic can be translated into SCL using IF statements. This is a crucial skill for PLC programmers transitioning from graphical languages to text-based programming.

You’ll see how the same control logic behaves identically in LAD and SCL, while gaining insight into when and why SCL can be more efficient, readable, and scalable for complex automation tasks.

Key Topics Covered:
• Introduction to SCL (Structured Control Language):
What SCL is, where it fits in IEC 61131-3, and how it differs from Ladder Logic.
• SCL in the PLC Scan Cycle:
How SCL code is executed within OB1 and how it follows the same scan principles as LAD.
• LAD to SCL Conversion:
Step-by-step conversion of a Ladder Logic network into SCL using IF / THEN / ELSIF statements.
• Logical Flow & Readability:
Understanding how contacts and coils translate into conditional logic in SCL.
• Practical Programming Insight:
When to use Ladder Logic vs. when SCL is the better choice in real-world projects.

Ideal For:
• PLC programmers transitioning from Ladder Logic to SCL
• Automation students learning text-based PLC programming
• TIA Portal users working with S7-1200 / S7-1500 controllers
• Engineers who want cleaner, more scalable PLC code
