01 / CAPABILITIES

Everything AI needs to work with TIA Portal.

A comprehensive set of tools that expose the TIA Portal Openness API to your AI assistant.

Write & edit PLC code

Let AI generate and modify ladder logic, function blocks, structured text, and more, directly inside TIA Portal.

Read & analyze projects

AI can inspect your existing TIA Portal projects, understand the logic, and suggest improvements or find bugs.

Hardware configuration

Configure PLCs, HMIs, and network devices. Add I/O modules and set parameters without manual clicking.

Full automation workflows

Describe a complete automation task in plain English and let AI handle the TIA Portal workflow.

HMI screen management

Create and modify HMI screens, add tags, and link them to PLC variables automatically.

Project version control

Open, save, archive, and manage multiple TIA Portal project versions through AI commands.

Compile & validate

Trigger compilations and catch errors before downloading. AI reads and interprets TIA Portal diagnostics.

Works with Cursor & Claude

A drop-in MCP server for any MCP-compatible AI client, including Cursor and Claude Desktop.

04 / GOOD TO KNOW

Frequently asked questions.

Everything you need to know before getting started.

What is an MCP server?

Model Context Protocol is an open standard that connects AI assistants to external tools. This server acts as the bridge between your AI client and TIA Portal so it can read, write and work with your projects.

Does this require an internet connection?

The MCP server runs on your local Windows machine and connects locally to TIA Portal. Your AI client may require internet access. Review its data settings to understand how project context is processed.

Which TIA Portal versions are supported?

TIA Portal V17, V18 and V19 are supported. Earlier versions are not officially tested. TIA Portal must be installed and licensed on your Windows machine.

Does it work on Mac or Linux?

TIA Portal is a Windows application, so the MCP server must run on Windows. A Windows virtual machine can be used from a Mac.

Do I need a TIA Portal Openness license?

The server uses the official Siemens Openness API. Check that your TIA Portal Engineering installation and license include Openness, and enable the required Windows user permissions.

What AI clients does it work with?

Use an MCP-compatible AI client such as Cursor IDE or Claude Desktop. Configure the executable path in the client’s MCP settings.

What happens after 12 months of free updates?

You keep the version you have downloaded. Further updates may require an optional update plan. Your existing license does not expire.

Can I get a refund?

A 14-day refund period applies if the server does not work with your TIA Portal installation. Contact support through the contact page for purchase and refund details.
