Automation software for industry
Industrial communication, automation workflows, and the tools around them.
TKH Software builds focused software for machines, production data and industrial processes: PLC connectivity, OPC UA, Modbus TCP, EtherNet/IP, Siemens S7, interfaces and reliable automation helpers.
Niche focus
- PLC communication and machine data
- OPC UA, Modbus TCP, EtherNet/IP and S7
- Desktop tools for technicians
- Backend services for production systems
Services
Software where automation meets production reality.
Clear, maintainable tools for companies that need machines, data and people to work together.
Automation Workflows
Effective systems that reduce repetitive manual work in production, maintenance and engineering.
Industrial Desktop Apps
Practical Windows tools for operators and technicians: configuration, diagnostics, data export and visualization.
APIs and Integration
Backend services that connect PLC data with databases, reporting systems, ERP, MES or custom business software.
Best fit
For teams that need software close to the machine.
We help where standard software ends one step too early: reading PLC data, connecting old and new systems, building technician-friendly tools, or turning production signals into reliable business data.
Tailor-made
The software is designed with PLCs, plant constraints and shop-floor workflows in mind.
Robust
Projects are built like maintainable software products, not temporary scripts.
S7 products
Start with the tool. Build with the library.
Two focused ways to work with Siemens S7 controllers—from a quick visual check to direct integration in C, C++ and C# applications.
For technicians and engineers
S7 Browser
A free desktop app for inspecting reachable Siemens S7 PLCs and exploring their data without opening a full engineering environment.
- Browse S7 connections and inspect PLC structure
- Useful for diagnostics, commissioning and quick checks
- Free download for Windows and macOS
For software developers
TKHC-S7
A licensed native C library with a .NET wrapper for secure communication with Siemens S7-1200 and S7-1500 controllers—including optimized data blocks.
