totally-integrated-claude
A Claude Code plugin for Siemens TIA Portal engineering automation.
Provides a routed skill framework covering the full TIA Portal Openness API surface — Python TIA Scripting for everyday tasks and C# Openness for advanced object-model work.
Features
- Automatic routing - one entry-point skill (
tia-openness-roadmap) selects Python or C# and loads the right domain skill
- Python TIA Scripting - full coverage of PLC blocks/tags, HMI, libraries, devices, project lifecycle via
tia-python
- C# Openness - nine domain skills covering every Openness API area (see table below)
- TIA Portal Add-In development — VS Code–based Add-In authoring workflow
- TIA Portal MCP server - work with your agent directly in TIA Portal V21 (separate installation required, see below)
- MCP write safety hooks - Claude Code blocks TIA Portal writes unless the call includes
confirm=true and a server-issued safetyToken
- Environment diagnostics - manually run
tia-doctor to check TIA Portal, Openness, Python TIA Scripting, and MCP prerequisites
Skills
| Skill | Purpose |
|---|
tia-openness-roadmap | Entry point. Routes all TIA Portal tasks to the correct implementation path and domain skill. Load this first for every TIA Portal task. |
tia-doctor | Manual diagnostic. Checks local prerequisites and reports exact remediation steps without mutating the machine. |
plc-code-analysis | Standalone. Multi-perspective security and quality analysis for PLC code (SCL/LAD/FBD) via SimaticML or MCP. |
tia-portal-mcp | Interactive. Direct TIA Portal interaction via MCP tools (browse tree, read/write logic, list tags, hardware config). |
tia-python | Python TIA Scripting: PLC blocks/tags/UDTs, HMI tags/screens, library types/versions, project lifecycle, CAx import/export. |
tia-csharp-common | C# foundation: TIA Portal process attach, ExclusiveAccess, Transaction, disposable patterns. Required first load for every C# task. |
tia-project-general | C# project & portal lifecycle: open, create, save, archive, retrieve, UMAC/UMC, language settings, diagnostics. |
tia-devices-general | C# device & device-item operations: hardware catalog, device creation/deletion, slot/subslot traversal, software containers, network connections, hardware parameters. |
tia-plc-operations | C# PLC software engineering: program/system blocks, PLC tags/UDTs, software units, Safety, alarms, OPC-UA, technological objects, watch/force tables, online/download, compare. |
tia-hmi-operations | C# Unified HMI: screens, screen items, elements, parts, tags, alarms, scripts, cycles, connections, dynamization, events, runtime settings, system services. |
tia-networks | C# topology: subnets, nodes, IO systems, port channels, addresses, IO timing. |
tia-simatic-drives | C# Startdrive / SINAMICS: drive controller access, drive engineering, motion control, download. |
tia-import-export | C# & Python import/export: SimaticML, AML/CAx, PLC blocks, HMI screens/tags/alarms, hardware AML, project data. |

Prerequisites
For Python TIA Scripting
- Siemens TIA Portal V17 or later
- TIA Scripting Python downloaded from Siemens Industry Online Support
- Python 3.12.x for the current
siemens_tia_scripting wheel
For C# Openness
- Siemens TIA Portal V17 or later
- TIA Portal Openness assemblies (installed with TIA Portal)
- .NET Framework 4.8 or later
For Add-In development
- Visual Studio 2022 or VS Code with C# Dev Kit
- TIA Portal Add-In SDK (available from Siemens Industry Online Support)
TIA Scripting Python is not installed from PyPI by package name. Download the
TIA Scripting Python ZIP from Siemens, then use one of Siemens' supported setup
paths:
- File import: unzip it and set
TIA_SCRIPTING to the extracted binaries
directory.
- Wheel install: from the extracted
binaries directory, install the matching
wheel file, for example:
cd C:\Path\To\Your\TIA_Scripting_Python\binaries
py -3.12 -m pip install .\siemens_tia_scripting-x.x.x-cp312-cp312-win_amd64.whl
To check a local machine, run the bundled doctor probe:
powershell.exe -NoProfile -ExecutionPolicy Bypass -File skills\tia-doctor\probe.ps1
For machine-readable output:
powershell.exe -NoProfile -ExecutionPolicy Bypass -File skills\tia-doctor\probe.ps1 -Json
Installation
Install from GitHub or clone this repository and link it locally while developing.
Claude Code
/plugin marketplace add Czarnak/totally-integrated-claude
Antigravity CLI
Install from GitHub:
agy plugin install https://github.com/Czarnak/totally-integrated-claude
For local development, load the plugin:
agy plugin validate
agy plugin install
Codex
Install the marketplace from GitHub:
codex plugin marketplace add Czarnak/totally-integrated-claude
From inside an interactive Codex session, you can use the slash-command form:
/plugin marketplace add Czarnak/totally-integrated-claude
Usage
Start every TIA Portal task by asking Claude to load the routing skill:
How do I read all PLC tag tables from an open TIA Portal project?
Claude will load tia-openness-roadmap, select the correct implementation path (Python or C#), and load the matching domain skill automatically.
TIA Portal MCP write safety
TIA Portal MCP write tools use a preview-then-apply workflow. First call the matching preview_* tool, review the summary/diff and currentStateHash, then pass the returned safetyToken to the write tool with confirm=true.
Examples:
| Write | Required preview |
|---|
update_block_logic | preview_update_block_logic |
create_tag_table, delete_tag_table | preview_create_tag_table, preview_delete_tag_table |
create_tag, update_tag, delete_tag | preview_create_tag, preview_update_tag, preview_delete_tag |
create_user_constant, update_user_constant, delete_user_constant | matching preview_*_user_constant tool |
add_network_device, configure_network_device | preview_add_network_device, preview_configure_network_device |
open_project, create_project, save_project, save_project_as, archive_project, close_project | matching preview_*_project tool |
Claude Code also loads hooks/tia-write-guard.ps1 through hooks/hooks.json as defense-in-depth. The MCP server is still the authority: other clients must use the same preview token flow.
Environment diagnostics
Use tia-doctor when TIA Portal automation fails because of missing local
prerequisites. It is a read-only PowerShell probe that checks TIA Portal,
Openness assemblies, membership in the Siemens TIA Openness Windows user
group, Python TIA Scripting, tia-mcp, and the bundled Siemens PLC language
server.
