Automation Pill - CASE Statement
Tired of long, hard-to-read IF...ELSIF...ELSIF...ELSE chains when checking one variable against many values? This quick tutorial introduces the elegant CASE statement in Structured Text!
In this video, you'll learn:
🔹 Why the CASE statement is often better than multiple ELSIFs.
🔹 The basic syntax of CASE...OF...ELSE...END_CASE in Structured Text.
🔹 How to handle single values, multiple values per branch, and default actions (ELSE).
🔹 A practical example showing how CASE simplifies logic like state machines or mode selection in CoDeSys.
Perfect for beginner and intermediate automation engineers, technicians, and students looking to write cleaner, more efficient PLC code using IEC 61131-3 standard programming.
