Key Capabilities

Deep dive into the features that make T-IA Connect the most powerful TIA Portal automation platform.

Full REST API Access

Control every aspect of your TIA Portal project via standard HTTP requests. Create and modify PLC blocks (OB, FB, FC, DB), manage tags, compile hardware, import/export data, and deploy to PLCs - all without opening the TIA Portal UI. Supports SCL, LAD, STL, and GRAPH languages.

Create, read, update, delete any PLC block
Import/export to XML, CSV, Excel formats
Compile and deploy to PLC hardware
Manage tags, UDTs, constants, and watch tables

GET /api/projects/blocks
POST /api/projects/blocks/compile
PUT /api/projects/tags
DELETE /api/projects/blocks/{name}

// 330+ endpoints available

PLCSim Advanced Simulation

Full programmatic control over PLCSim Advanced instances. Create virtual controllers, download programs, read and write tags in real-time, manage simulation profiles, and run automated test sequences - all via API calls.

Create and manage virtual PLC instances
Read/write tags with batch operations
Save and load simulation profiles
Automated testing with result collection

plcsim_create_instance("CPU_1")
plcsim_power_on()
plcsim_run()
plcsim_read_tag("DB1.Temperature")
// > 85.4

plcsim_batch_write([
  { tag: "DB1.Setpoint", value: 90.0 },
  { tag: "DB1.Enable", value: true }
])

HMI & WinCC Automation

Programmatically create and configure HMI screens, tags, alarms, scripts, and animations. Build complete operator interfaces through code, manage connections to PLCs, and configure runtime settings without manual design work.

Create screens, elements, and animations
Manage HMI tags, alarms, and connections
Configure scripts and event handlers
Set tag bindings and dynamizations

create_hmi_screen("Overview")
add_screen_item("Overview", {
  type: "IOField",
  tag: "Temperature",
  x: 100, y: 200
})
set_visibility_animation("Alarm_Icon", {
  tag: "DB_Alarms.Active",
  visible_when: true
})

AI-Powered Engineering

Leverage Large Language Models to generate PLC blocks that are context-aware of your specific project. The AI reads your existing blocks, tags, and UDTs to produce code that integrates seamlessly. Supports SCL and LAD generation with automatic import and compilation.

Context-aware code generation from project data
40 pre-built industrial patterns (motors, valves, safety)
AI copilot for troubleshooting and documentation
Community knowledge base with shared LLM tips

generate_and_import_block({
  name: "FB_MotorCtrl",
  language: "SCL",
  description: "Motor control with
    start/stop, fault detection,
    and runtime counter",
  device: "PLC_1"
})
// Block generated, imported & compiled

Version Control & CI/CD

Built-in Git-like version control for TIA Portal projects. Create branches, commit changes, merge, push to remotes, and build automated CI/CD pipelines. Define reusable pipeline templates for standardized deployment workflows.

Branch, commit, merge, push, pull operations
Pipeline templates for automated workflows
Project snapshots and history tracking
Multi-user workspace management

vcs_init()
vcs_branch_create("feature/new-recipe")
// ... make changes ...
vcs_commit("Add recipe management")
vcs_merge("main")

pipeline_run("deploy-to-production", {
  target: "PLC_Line_1",
  compile: true
})

CODESYS Integration

Not limited to Siemens. T-IA Connect also supports CODESYS projects with the same API-driven approach. Create projects, manage POUs, build and deploy - extending your automation toolkit beyond a single vendor.

Create and manage CODESYS projects
POU creation in Structured Text and Ladder
Build, compile, and deploy
Hardware catalog browsing and device management

codesys_create_project("MyProject")
codesys_add_device("WAGO_PFC200")
codesys_create_pou("PLC_PRG", "ST")
codesys_set_pou_code("PLC_PRG", code)
codesys_build()
// Build successful: 0 errors
