Siemens TIA Portal Program Structure and Best Practice
How professionals lay out a TIA Portal project so it is still readable in five years: modular blocks, FBs and instances, UDTs for I/O, arrays and shift registers, a structured drive block, and two live workshops that clean up real messy programs.
Free to learn. Verifiable certificate £19 when you pass the final exam (optional, VAT included).

Outcome
What you will be able to do
Start a project the right way, structure it into modular function blocks with single and multi-instances, describe I/O and machines with UDTs, use arrays and shift registers where they belong, add a structured VFD control block, upload from a PLC, and refactor a chaotic program and its data into something a colleague can maintain.
- Start a TIA Portal project cleanly and know what TIA Portal changed from SIMATIC Manager
- Structure a program into modular blocks that scale
- Use function blocks with single and multi-instances correctly
- Describe I/O and machines with UDTs and use arrays and shift registers
- Add a structured VFD control block and upload from a running PLC
- Refactor a messy program and chaotic data into a maintainable project
Software
TIA Portal V21 (21-day trial) with S7-PLCSIM; V17 or later also works
Hardware
