Both online converters are currently free. Engineering review is always required.

Two focused tools

Choose what you need to convert

PLC logicFree

PLC Logic Converter

Convert one Siemens OB, FB, or FC into a reviewable Rockwell Studio 5000 package.

Input: one compatible TIA Portal XML block Output: L5X, programmer report, and ASCII fallback

Convert PLC Logic Checking service

Data structuresFree

Data Structures Converter

Rebuild Siemens project data as Rockwell datatypes, Controller Tags, and global data structures.

Input: one complete TIA XML export ZIP Output: Rockwell import package with reports and fallback files

Required: the ZIP must be created with the ConvertAutomation TIA XML Exporter. Other export packages are not supported.

How it works

One export workflow, two conversion paths

Export from TIA Portal

We recommend using the ConvertAutomation TIA XML Exporter to prepare your files. Other compatible XML export tools may be used for PLC logic conversion, but our Exporter is required for the Data Structures Converter.

Choose the converter

Upload one XML block for PLC logic, or the complete Exporter ZIP for project data structures.

Download and verify

Use the generated package as an engineering starting point, then review, import, test, and validate it.

Engineering review required. Generated files are conversion aids, not approved machine logic. Qualified automation personnel must review and test every result before use.

Free Windows export tool

Export TIA Portal XML for both converters

Use the ConvertAutomation TIA XML Exporter to export individual PLC logic blocks or create the complete ZIP required by the Data Structures Converter.

Export one selected PLC block
Export all PLC blocks, Tag Tables, Data Types, and UDTs
Create the complete ZIP accepted by the data converter

FAQ

Answers to common questions

What is the difference between the two converters?

The PLC Logic Converter converts the Siemens code from one OB, FB, or FC into a Rockwell Studio 5000 L5X file. The Data Structures Converter processes a complete Siemens project export created with the ConvertAutomation TIA XML Exporter. It rebuilds the project data structure—including Tag Tables, PLC Data Types, UDTs, and global DBs—as Rockwell Data Types and Controller Tags, delivered in importable L5X files.

Is a Siemens TIA Portal XML export required?

Yes. Both converters require files exported from Siemens TIA Portal in XML format. For a single PLC logic block, you may use any compatible XML export tool. For data-structure conversion, the complete ZIP must be created with the ConvertAutomation TIA XML Exporter.

Do these converters replace a PLC programmer?

No. These tools are designed to assist qualified automation professionals, not replace their expertise or engineering judgment. They simplify repetitive conversion work and help reduce manual transcription errors. Every generated result must still be reviewed, tested, validated, and approved by a qualified PLC programmer before use.
