Module 6 – The PTF principle

Learning objective

Understanding the methodological foundation: process, technology, function.

Explanation

1. Process → defines states.

2. Technology → defines signals.

3. Function → defines zones.

Only when all three levels are clear does a clean SEQ emerge.

Task

Analyze a simple process (e.g., pressing, sorting, conveying). Write down:

• Process steps,

• required sensors/actuators,

• corresponding zones.
