scl-syntax

SCL (Structured Control Language) syntax assistance for Siemens TIA Portal V20+ PLC programming. Generates error-free SCL code using native functions from a 222-function database. Bilingual support (Italian/English). Works with S7-1200/S7-1500 controllers. Use this skill when: - Generating SCL code for Siemens PLCs - Creating Function Blocks (FB) or Functions (FC) - Working with TIA Portal SCL programming - Reviewing or debugging SCL code - Questions about SCL syntax, functions, or best practices - Converting logic to SCL from other languages - Implementing timers, counters, state machines in SCL
