Core Capabilities

Industrial Power | Developer Experience

We've abstracted the complexity of TIA Portal and Siemens engineering into a clean, modern interface that IT teams love.

API Openness & Scripting

Automate XML/SCL block generation and compilation via a standardized REST API for TIA Portal.

Diagnostic & Data Mining

Access PLC variables (Tags/DBs) in JSON for diagnostics, IIoT, and predictive algorithms.

CI/CD Deployment

Integrate Siemens PLCs into your DevOps pipelines. Automated load distribution and PLC unit testing.

API Protection

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

Native WebSockets

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

Signed Code

Certified binaries and PowerShell scripts to ensure toolchain integrity.

TIA Monitoring

Proactive monitoring of Siemens process state and memory.

Orchestration

Intelligent queue (StaDispatcher) to manage concurrent access to TIA Portal.

Service Mode

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

Tech Stack Integration

Speak the language
of Modern IT.

Forget byte offsets and proprietary protocols. T-IA Connect abstracts Siemens complexity at the driver level, serving typed JSON schemas ready for your React dashboards or Python automation pipelines.

Model Context Protocol (MCP)

PLC Code Generator
AI-Assisted (LLM)

The first MCP server for industry. Connect TIA Portal to Gemini, Claude, or Ollama for automatic SCL code generation, DB documentation, and AI-assisted refactoring.

TIA Co-Pilot

Connected to TIA V21

Gemini 1.5 Pro

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 the Motor_Drive UDT. Here is the SCL code for FB_Conveyor_Control:

FB_Conveyor_Control.sclSCL

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

Understand your Context.
Not just generic code snippets.

The first MCP server for industry. Connect TIA Portal to Gemini, Claude, or Ollama for automatic SCL code generation, DB documentation, and AI-assisted refactoring.

Discover the AI Generator

Bring Your Own Model

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

Context-Aware Generation

The AI reads your PLC data types before writing code. No more mismatched variable names.

Local Execution

Keep your IP safe. Run local LLMs via Ollama and never send your proprietary logic to the cloud.

“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.”
