T-IA Connect

Automate TIA Portal engineering from API to validation.

T-IA Connect is a complete engineering automation platform for Siemens TIA Portal: REST API, MCP, Workplan-guided execution, PLCSIM, Test Harness, VCS, docs/RAG and reports.

TIA Portal Engineering Automation Platform

T-IA Connect wraps Siemens TIA Portal in a controllable automation layer for API calls, AI-assisted execution, simulation, tests, documentation and integration workflows.

Drive project creation, blocks, tags, hardware, compilation and reports through a documented HTTP/JSON API over TIA Portal Openness.

Connect Claude, ChatGPT, Cursor or local models to real project context, then guide actions through a structured Workplan instead of free-form chat.

Close the loop with simulation, automated PLC tests, source control, CI/CD workflows and engineering evidence you can review.

Token authentication and locking of critical routes (Write/Delete).

Real-time feedback via SignalR for tracking long-running TIA tasks.

Certified binaries and PowerShell scripts to ensure toolchain integrity.

Proactive monitoring of Siemens process state and memory.

Plan, sequence and audit multi-step engineering actions before they touch TIA Portal.

Designed to run headless as a background task on your Windows engineering servers.

Run the local T-IA Connect bridge and access projects through REST API and MCP instead of manual UI-only operations.

Use AI and project context to prepare sequenced actions: create, modify, compile, simulate, test, document and report.

Run the approved plan through API actions, PLCSIM/Test Harness checks and VCS-friendly outputs.

01FUNCTION_BLOCK "FB_MotorControl"

08#Motor_Run:= (#Start_Command OR #Motor_Run) AND #Stop_Command AND #Safety_Healthy;

Workplan: compile, PLCSIM check and report ready for review.

The MCP layer connects TIA Portal to Gemini, Claude, ChatGPT, Cursor or Ollama, but the product value is the workflow around it: project context, Workplan, API execution, PLCSIM checks and reviewable outputs.

Create a Function Block (SCL) to control a conveyor belt. Use the UDT "Motor_Drive" we defined in the library.

Reading project context (Library/Types/Motor_Drive)...

I've analyzed theMotor_DriveUDT. Here is the SCL code forFB_Conveyor_Control:

FUNCTION_BLOCK "FB_Conveyor_Control" VAR_INPUT Enable : Bool; Reset : Bool; Drive_Ref : "Motor_Drive"; END_VAR BEGIN #Drive_Ref.ControlWord.%X0 := #Enable; IF #Reset THEN #Drive_Ref.ControlWord := 16#0480; END_IF; // Ramp Generator IF #Enable AND #Drive_Ref.StatusWord.%X2 THEN #Drive_Ref.SpeedSetpoint := 1500.0; END_IF; END_FUNCTION_BLOCK

A standard AI chat can propose text. T-IA Connect exposes real TIA Portal project context through MCP, then channels changes through API actions, Workplan steps, simulation, tests, reports and source control.

Compatible with Gemini Pro, Claude 3.5 Sonnet, or run offline with Ollama (Llama 3, Mistral).

Turn AI suggestions into sequenced engineering steps that can be reviewed, executed, tested and traced.

Keep your IP under control. Use your own AI key or local LLMs via Ollama and run the TIA Portal automation layer locally.

“I begin to test t-ia connect with m'y trial app and i liké it too much, it help you to make any thing to the Tia projects with simple click. ”

“. Giá trị mới chỉ đang ở trạng thái "Prepared" (Chuẩn bị) Trong bảng khai báo biến (phần Expression phía trên), bạn sẽ thấy: Cột Value của start vẫn là FALSE. Cột Prepared Value của start mới là TRUE (hiển thị màu xanh dương). Giải thích: Trong CODESYS, khi bạn nhập giá trị mới lúc đang Online, nó chưa được ghi vào bộ nhớ ngay mà chỉ nằm ở danh sách "chờ". Cách xử lý: Sau khi PLC đã ở chế độ RUN, bạn cần nhấn Ctrl + F7 (Write Values) để nạp giá trị TRUE từ cột "Prepared Value" vào cột "Value" thực tế.”
