EAE Basic Function Block Creation

Create or modify Basic FBs with state machine logic (ECC) and Structured Text algorithms.

CRITICAL RULE: ALWAYS use this skill for ANY operation on Basic FB files.

• Creating new Basic FBs
• Modifying existing Basic FBs (adding events, variables, states, algorithms)
• NEVER directly edit .fbt files outside of this skill

Basic FB = State Machine + Algorithms

• ECC (Execution Control Chart) for state transitions
• Algorithms in ST (Structured Text) for computation
• No internal FBNetwork (unlike Composite)

Quick Start

User: Create a Basic FB called Calculator in MyLibrary that multiplies two REALs
Claude: [Creates .fbt with ECC + REQ algorithm: Result := Value1 * Value2]
