TIA Portal XML to Rockwell L5X

Convert one Siemens OB, FB, or FC into Rockwell Studio 5000 L5X files. This guide covers the export, conversion, and checks before import.

Go to PLC Logic Converter →Get TIA XML Exporter

Convert your block in three steps

Prepare your XMLSelect one Siemens block in our TIA XML Exporter and export it as XML. For FBD, convert the block to LAD in TIA Portal before export for better Ladder conversion results.
Upload and convertUpload the XML to the PLC Logic Converter and follow the instructions shown in the app.
Download and reviewDownload the generated package and read the accompanying report. Follow the app instructions, review the result, and test it in Studio 5000.

What you receive

  • L5X files: the primary output for import into Studio 5000. A valid import does not guarantee equivalent behavior.
  • Programmer report: conversion notes, manual actions, and import guidance where applicable.
  • Text fallback — if L5X import fails: use *_ROCKWELL.txt to create an empty Ladder routine in Studio 5000 and paste the ASCII code into it. Then manually add each rung's comment from the text file to the corresponding rung, one by one. Check the conversion status in the file and verify the routine before use.

Languages and XML sources

OB, FB, and FC blocks in LAD, FBD, SCL, and STL are accepted, with the best results observed for LAD and SCL. Compatible XML files from Siemens libraries and other users have also been converted successfully; our Exporter is recommended, but is not mandatory for single-block conversion.

Tested TIA Portal versions

The converter was developed using V19 exports, and V21 exports have also been converted successfully. V20 compatibility is expected but has not been directly verified. Results still depend on the block's instructions, addressing, and dependencies; a single block does not include the entire target project.

Before using the L5X

  1. Read the report: resolve manual actions and use the indicated import location.
  2. Check the target project: controller and Studio 5000 versions, tag scopes, data types, initial values, arrays, aliases, routines, AOIs, and UDTs.
  3. Verify behavior: instructions, timers, counters, arithmetic, edge detection, timing, and sequencing.
  4. Test and approve: complete offline checks and controlled testing before commissioning.
Qualified engineering review is required. Generated files are conversion aids. Do not download logic to a controller before review, testing, and approval.
