STL Language – BTI & IBT Instructions Explained (BCD Code Conversion)
In this tutorial, we focus on BTI and IBT instructions in Siemens STL language, essential for BCD (Binary-Coded Decimal) conversion:
BTI – Converts BCD (Binary-Coded Decimal) to Integer
IBT – Converts Integer to BCD (Binary-Coded Decimal)
You’ll learn:
✅ What BCD is and why it’s used in PLC programming
✅ The difference between BTI and IBT
✅ Step-by-step implementation in TIA Portal with S7-1200/1500 PLCs
✅ Real-world automation examples where BCD conversion is needed
✅ Best practices for accurate numeric data handling in STL
By the end of this lesson, you’ll be able to seamlessly convert between BCD and Integer formats in your Siemens PLC programs using STL instructions.
