A personal open-source project by Łukasz Czarnacki that lets an assistant search and read TIA Portal, STEP 7 and WinCC Unified docs live.
For controls engineers: ask about a PLC or HMI setting and have the assistant pull up the matching manual page.
The solid-modeling engine that does booleans, fillets and shelling is now free under Apache 2.0, and until now only legacy licensees could get it. A free Python wrapper, smlibpy, adds an MCP server, so AI agents can build parts and export STEP files. The poster works at AWV Informatik, the company behind smlibpy.
For engineers: an agent can now draft real CAD geometry on an industrial-grade CAD kernel.
When the SCADA vendor ships MCP itself, the question stops being if and becomes who approves writes.
For Controls and SCADA engineers:
Version 2.7.4 drives TIA Portal V20 or V21 to add hardware, generate tags, DBs and SCL or LAD blocks, and compile. It is free under MIT and is not made by or affiliated with Siemens.
For controls engineers: generate PLC blocks and put a TIA Portal project under Git from one prompt.
