Write Your First PLC Program | Ladder Logic & Scan Cycle Explained

Описание: Start Writing Code: Ladder Logic & PLC Scan Cycle Explained
This first installment of Chapter 7 in our PLC Training Series marks the transition from hardware configuration to actual programming.

In this lesson, we explore the "heartbeat" of the controller—the PLC Scan Cycle—and dive into the Siemens TIA Portal programming interface.
We will move beyond theory to write our first lines of Ladder Logic (LAD), create modular Functions (FC), and understand the crucial differences in addressing methods.

Key Topics Covered:

The PLC Scan Cycle: A deep dive into how the PLC reads inputs, executes code, and updates outputs (and why execution order matters).
Program Structure: Understanding Organization Block 1 (OB1), Networks, and Rungs.
Ladder Logic Essentials: Navigating the Instructions Library and building your first logic program.
Functions (FC) & Addressing: How to create a Function (FC) and implement both Direct and Indirect addressing.
Developer Tools: How to use Cross-Referencing to track tags and debug your code efficiently.

Ideal For:
Beginners taking their first steps in writing actual PLC code.
Automation students needing to understand the core execution cycle of a PLC.
TIA Portal users looking to understand modular programming with FCs.
